Best Ever!

12 years ago
I bought both shampoo & conditioner about a month ago, along with my usual brand. I absolutely LOVE this conditioner (it smells great too)!! I live in Florida where it gets very humid during the summer months, which means my hair tends to become coarse, brittle, frizzy and basically hard to manage. My hair is very thick and below my shoulders. When I use Matrix Total Results Sleek Conditioner my hair is soft and manageable. It feels awesome! I've experimented to know for sure whether it was the product or something else. Every time I've used something other than this conditioner, after a day my hair becomes hard to manage and just doesn't feel that great. Please....Please....Please DON'T ever change the formula!!! #Imsoldforlife!

Where is the silk and wheat protein?

11 years ago
Even I know as a true former Matrix user that this product definately needs the silk amino acids and wheat protein put back in this product. I can't say that it's totally bad, but it does moisturize to a point that my hair just pops when I run my hand or a brush through it. That usually means something is off balance. I have to combat it with the Redken Cat or Chi Keratin Mist. It helps somewhat. And then I have the issue with the residue it leaves behind as well. Not the cleanest feeling.

I would buy this product again and again! Smells amazing

2 days ago
my favorite thing about the matrix smoothing conditioner is the fact that it smells absolutely amazing and it is lightweight and it doesn’t leave your hair feeling greasy or way down. The packaging is easy to use. Obviously it speaks for itself and it absorbs so well that a little bit of product who is a long way and I use this every few days and have been using it for a month and my hair has never felt healthier and looked better. It’s got a smooth soft shine to it that isn’t greasy. It doesn’t leave my hair with flakes or dandruff. I’m obsessed with this entire line.

Thank you so much for your decade of loyalty to Matrix, and we are deeply sorry that the renovated formula has let you down. Finding a true holy grail conditioner for thick, long, and curly hair is rare and precious, and hearing that our updated formula has turned into a dry, unmanageable experience with an overpowering scent is truly heartbreaking.

Terrible new formula

5 days ago
It would have been nice to know the formula changed. I finished my last liter and opened the new one I had ready in the shower. I thought it had expired!! My original conditioner was white in color and the new one came out yellow!! It definitely did not perform or smell as great as the original. Extremely frustrated to research and find out the formula changed. Now I have to figure out how to return everything and spend more time and money finding a decent replacement product. I have been buying the Sleek line for well over 10 years! The hassle of refunds/returns and replacements is going to be a nightmare.

No, I do not recommend this product.

  • No warning about NEW formula.  Black lettered Matrix is new formula.
  • Originally white with a great smell. Now yellow and smell is not fresh.

Thank you so much for your 10+ years of loyalty to our Sleek line, and we are deeply sorry for the shock, frustration, and disruption this has caused to your routine. We completely understand why you thought your new liter had expired—going from a pure white, creamy conditioner with a clean scent to a yellow formula with an unfamiliar fragrance and runny performance is alarming, and you deserved clear communication on the packaging before opening it in the shower. We hear you loud and clear on how exhausting and frustrating it is to research, start from scratch, and deal with the "nightmare" hassle of returns. We want to remove that stress for you entirely.

We are deeply sorry to hear that the updated Mega Sleek conditioner has let you down so completely. The original Shea Butter formula was beloved specifically for its rich slip, effortless detangling, and deep softening power, and hearing that our new Jojoba Oil formulation performs worse than everyday drugstore alternatives while carrying an unpleasant scent is heartbreaking. While our intention was to transition to a 100% vegan formula, we hear your frustration loud and clear: removing Shea Butter stripped away the exact benefits that made this product a salon staple.

New Formula Is absolutely horrible!’

The new formula is absolutely horrendous. It is no longer shiny, smooth and bouncy. I have used the old formula ever since it came out and I cannot believe that matrix changed it. After reading so many reviews online on Reddit on Facebook on Instagram it is a huge miss for matrix! Please bring the old formula back! I have 2 L bottles that are just garbage at this point. My hair has looked so horrible since moving to the new formula. I have no shine. I have breakage. I have frizz instantly absolutely frustrating. This is for both the shampoo and conditioner.

We are deeply sorry to hear that the updated Mega Sleek conditioner let you down with its runny consistency, overpowering scent, and lack of detangling power.

Conditioner Formula Change Horrible!

The new conditioner formula is horrible! I’ve been using this for decades and I’m so sad. Please change it back. It’s now yellow, chunky, weighs the hair down, and the scent is strong and unpleasant.

This conditioner has been an absolute god send this summer. Like most cult headed people, my girls get extremely dry during the summer month due to the heat, chlorine in pools, and salt water.

New formulation is terrible and ineffective!

a month ago
I have used both the Matrix Mega Sleek shampoo and conditioner for over a decade but the new formula is not at all comparable. I'm so disappointed! The conditioner does not have any smoothing or sleek effect. Comparing the results I'm used to with old formulation to now using the new reformulation, my hair now looks frizzy, dull, and not at all smooth. Once styled, my hair definitely does not have the same shine or finish that the old formula left it with. It also does not feel moisturized or nourished after using the reformulation and is markedly more tangled. Additionally, the conditioner itself and the scent it leaves in the hair is *extremely* vanilla-y and kinda cheap/off-putting, a huge departure from the old formula. I had stocked up at a liter sale without realizing Matrix had reformulated (an indication/label would have been nice). I will definitely be returning and looking for something significantly more effective and that doesn't have an artificial baked good scent.

No, I do not recommend this product.

Thank you so much for being a loyal user of Matrix Mega Sleek for over a decade, and we are deeply sorry for the disappointment and frustration this reformulation has caused you—especially after stocking up during a liter sale. You raise a very fair point regarding packaging transparency: when a product undergoes a major overhaul in both performance and fragrance, our customers deserve clear labeling so they know what to expect before buying in bulk. In our shift to a 100% vegan formula, replacing Shea Butter with Jojoba Oil and introducing a warm gourmand fragrance (which carries strong vanilla, caramel, and sweet notes), we recognize that the rich moisture, effortless slip, and subtle salon finish you relied on for ten years were lost. Seeing your hair left frizzy, dull, tangled, and smelling like a sweet baked good is far from the professional quality you expect from us. We completely support your decision to return your liter bottles. If you experience any issues or pushback returning them to your retailer, please contact our Matrix Consumer Care team directly at 1-888-777-6396 (Monday–Friday, 9:00 AM – 5:30 PM EST). We will make sure your return is handled smoothly, issue a direct refund voucher if needed, and share your feedback on packaging transparency and fragrance directly with our brand leadership.

Thank you for sharing your experience, and we are so truly sorry to hear about the unpleasant reaction you had to our new formula. Experiencing a lingering scent that causes headaches—and having to use a second conditioner just to get basic results—is completely unacceptable, especially for a loyal customer who purchased our large 33.8-ounce liter bottles. When we renovated the Mega Sleek line to be 100% vegan, we replaced the original rich Shea Butter with Jojoba Oil and introduced a new, warm fragrance profile. However, we recognize that this updated scent can be overwhelming and that the lighter formula lacks the deep conditioning performance you relied on for years.

Matrix Mega Sleek Made Me Love My Hair Again

a month ago
Matrix Mega Sleek Made Me Love My Hair Again I received the Matrix Mega Sleek Smoothie Supreme Mask, Smoothing Conditioner, and Smoothing Shampoo complimentary from Influenster, and I am genuinely blown away by how well they worked for my hair. I have a mix of 2C, 3A, 3B, and 3C curls that are high‑porosity, often dry, and now more than 50 percent white. The new coarse texture has made my curls feel unruly and harder to manage, and it’s been tough to feel like myself as the gray has come in. These products changed that for me. My curls were soft, shiny, and bouncy, and they popped in a way I haven’t seen in a long time. I was worried the line might leave buildup, but it didn’t at all. Everything rinsed clean, and my hair felt hydrated instead of coated. On the rare days I wear my hair straight, this line impressed me even more. Nothing has kept my frizz under control the way Mega Sleek has. The smoothness lasted, the shine stayed, and my hair didn’t puff out by midday. I loved these products so much that I immediately purchased the Mega Sleek Anti‑Frizz Topcoat Serum. It was the perfect finishing touch. Matrix Mega Sleek didn’t just make my hair look better. It made me feel like me again. Highly recommend for anyone with curls, high porosity, or coarse grays who wants softness, shine, and real frizz control.

Severely disappointed

I absolutely loved this conditioner for YEARS. I have very fine and long hair but it’s naturally curly/wavy, and this was the only thing that would keep my hair from looking like a frizzy half curly half straight mess. I am SO disappointed they changed the formula so drastically as the results I got from my latest bottle has me turning away from this line forever. I was skeptical but optmistic after reading some reviews of others who used to love this conditioner before the formula change. Some said the smell was awful - I don’t mind the smell so much, but I do prefer the more subtle scent of the old formula. Surely this new formula couldn’t be THAT bad, right? Unfortunately I was wrong. My hair felt so incredibly dry after showing with this and the texture was just awful. My hair felt like hay when it used to feel so silky and smooth. Now starts the frustrating journey of trying to find a different conditioner that actually works for me, but one thing is for sure - I will never be purchasing this conditioner again, and it breaks my heart.

No, I do not recommend this product.

Thank you so much for sharing your heartfelt story with us. As someone with fine, long, and naturally wavy/curly hair, finding that one "holy grail" product to tame frizz and define your curl pattern is rare, and we are so truly sorry that our new formula broke your heart and left your hair feeling dry and like hay instead of silky smooth. When we renovated the Mega Sleek line to be 100% vegan, we replaced the original rich Shea Butter with a lighter Jojoba Oil base. While this was intended to provide weightless smoothing, fine curly and wavy hair often relies on the deep, protective lipid barrier that Shea Butter provided to lock in moisture and align natural wave patterns. Without it, the new formula can leave delicate, porous strands feeling stripped and straw-like rather than hydrated. We hear your frustration completely and want to take care of you. Please contact our Matrix Consumer Care team directly at 1-888-777-6396 (Monday–Friday, 9:00 AM – 5:30 PM EST) so we can issue a full refund voucher. If you are open to recommendations for your fine, wavy texture, our team would also love to help you transition to a formula that brings back that silky softness—such as our A Curl Can Dream line for curl definition or our Food For Soft line for deep, weightless hydration.

Thank you so much for sharing your feedback with us! We are absolutely thrilled to hear that you love the packaging, enjoyed the scent, and that the conditioner left your hair feeling soft and free of any heavy residue. It is also wonderful to hear that even when you accidentally applied it to your roots, you didn't experience any issues with heaviness or buildup, which is a great testament to the weightless slip of our new Jojoba Oil-infused formula. While we generally recommend focusing conditioner on the mid-lengths to ends to keep your roots as voluminous and fresh as possible, you can absolutely rest easy knowing that the lightweight formula is forgiving if a little bit makes its way to the top. If you ever have any questions or need styling tips to get the absolute most out of your Mega Sleek routine, please don't hesitate to reach out to our Matrix Consumer Care team at 1-888-777-6396 (Monday–Friday, 9:00 AM – 5:30 PM EST)—we are always here to help!

Thank you so much for being an incredibly loyal, 20-year user of Matrix Sleek, and we are deeply sorry that the renovated formula has let you down. We completely understand your disappointment, especially since the previous formula was a staple for you for two decades. In our recent transition to a 100% vegan formula, we replaced the original Shea Butter with a lighter Jojoba Oil base; however, we recognize that on certain hair types, this new blend can sit heavily on the hair shaft, leaving it feeling greasy and weighed down rather than clean and smooth. Since this experience is far from the professional salon results you deserve, we want to make this right. Please contact our Matrix Consumer Care team directly at 1-888-777-6396 (Monday–Friday, 9:00 AM – 5:30 PM EST) so we can personally help you find a lighter, more suitable smoothing alternative from our collections.

Terrible update to the formula

I’ve been an avid Mega Sleek user for over 20 years. I have long, thick hair and this product has been amazing until recently. It is obvious that the formula has changed, and now there are dyes in it (not sure why that would be necessary for hair product). I now dread brushing my hair after using the conditioner. My hair doesn’t feel soft, feels super dry and tangled. Please change back to the original formula. Unfortunately with the new formula, I can no longer use your product.

Hydrating Conditioner — Highly recommend!

2 months ago
My hair has been so much softer since I started using this conditioner in my routine. I love the packaging too, it’s easy to dispense the perfect amount. My hair feel lightweight, soft, and healthy. I highly recommend if you have been looking to try a new hydrating conditioner.

We hear you, and we are so incredibly sorry. Having a favorite product you've trusted for 20 years change on you is so disappointing, especially when it leaves your hair feeling dry and tangled instead of soft and manageable. We take your feedback very seriously. We are sharing your experience directly with our Product Development team so they know how much the original shea butter formula, scent, and detangling slip are missed. In the meantime, to help get that effortless slip back, we highly recommend misting our Color Fanatic Multi-Tasking Leave-In Spray onto your damp hair post-shower to melt away knots and restore silkiness. Thank you for being such a loyal part of our Pureology family for two decades. Your honesty means the world to us! 💜

Terrible!

I am so disappointed in this new formula. I don’t like the strong smell- .like I’ve got coconut scent sunscreen in my hair.. I’ve used this product for over 15 years. I feel like I’ve been bamboozled. Why did you make this change? The results of using the new conditioner is not the same. My hair is now flat without body, unlike the previous formula. Can I get a refund? Or can you send me the old formula?

No, I do not recommend this product.

Dear valued customer, thank you so much for your fifteen years of loyalty, and we are deeply sorry that our updated Mega Sleek formula has let you down. To transition to a 100% vegan formula, we replaced the original Shea Butter with Jojoba Oil and introduced a new warm caramel-pistachio fragrance, which can carry a tropical, coconut-like scent that we understand is overwhelming for some. While we no longer manufacture or stock the original formula, we want to make this right for you. Please feel free to return the bottle to your original retailer for a full refund, or contact our Matrix Consumer Care team directly at 1-888-777-6396 (Monday–Friday, 9:00 AM – 5:30 PM EST) so we can help you find a better alternative, such as our lightweight Food For Soft hydrating line.

Hydrating and less frizz

2 months ago
I’ve been using this conditioner along with the smoothing shampoo. I have wavy hair, and typically after I wash my hair, it gets frizzy almost immediately. After using this the last month, I’ve definitely noticed a reduction in frizz after washing and especially the next day. I’ve also found that the longer you use this line, the better it works. It looks shinier and feels more hydrated. The shampoo and conditioner bottles are almost identical, and I’ve definitely confused them a couple times in shower, so I’d recommend differentiating them a little more.

What did you do?! Why would you change the formula on the shampoo and conditioner when it was wonderful from the start? The new formula is not nearly as good as the original and we are highly disappointed. The price went up and the results went down. Bring back the old formulas!

No, I do not recommend this product.

We are so incredibly sorry for the disappointment and frustration! We know how upsetting it is when a routine you’ve loved and relied on for years changes, especially when you feel the price has gone up while the results have gone down. Our formula updates are typically made to meet new global clean-beauty regulations and to upgrade our active ingredients, but we clearly missed the mark for you. There is nothing worse than losing the beautiful results you used to get, and we hear your call to bring back the original formulas loud and clear. We are sharing your feedback directly with our executive and product teams today. Thank you for your honest and passionate feedback—our long-term customers are the heart of , and we truly appreciate you speaking up. 💜

If it’s ain’t broke, DON’T CHANGE IT & CHARGE MOR

I LOVED the original formula and have used it for years… the new formulas leaves my hair stringy, limp, and lifeless. The old formula was thicker and more moisturizing, and it always left my hair shiny and soft. If you want to make a new product and charge more, then leave the old one alone and sell BOTH.

No, I do not recommend this product.

We hear your frustration completely, and you make an incredibly smart point. Having a formula that used to make your hair feel thick, shiny, and soft suddenly leave it feeling limp and lifeless is so disappointing—especially when you've been a loyal fan for years. Your suggestion to keep the classic formula available alongside new innovations makes total sense, and we are sharing this feedback directly with our brand leadership and product teams. We want to hear what our long-term community thinks, and your voice is so important to us. Thank you for your honesty and for sticking with us over the years. We truly hope we can win back your trust! 💜

Smells amazing

The conditioner has a nice fragrance and spreads easily though my hair. It made my hair feel smoother and more manageable, though it needed to use it regularly for the best results

If you’re looking for frizz control…

2 months ago
Before I even put this in my hair the smell took me to the beach with a hint of “62”. I’ve used this and the shampoo until there wasn’t hardly any left. This conditioner is creamy and somewhat of a thick texture. I start about midway down my hair and work the conditioner down and then rinse. This conditioner combined with the matching shampoo leaves my hair freeze free every time.

Inferior to the old formula

2 months ago
What a disappointment and an inferior product. I have been using Mega Sleek conditioner (with Shea Butter) since back when it was called Sleek Look, so at least over a decade. I was thrilled when I finally found the Shea butter formula because it was the only conditioner that gave my hair enough moisture, slip, and sleekness without making it feel filmy or dried out like hay. Back before I found the old Mega Sleek with Shea butter conditioner, I had probably spent thousands of dollars trying to find just the right conditioner for my mixed hair type that I straighten regularly. This new formula with jojoba oil makes my hair feel filmy, limp, and (ironically) dry simultaneously. It’s yellow and runny, has an overpowering unnatural scent, and doesn’t absorb into my locks like the old formula. Worst of all, it doesn’t leave my hair bouncy, shiny, or flowing like the old shea butter formula. Why change a good thing? Why not split this line into two options to keep offering the old formula alongside the new? I now fear I’ll need to spend thousands more dollars in wasted conditioners searching for something else to replace the Mega Sleek conditioner I used to love. Bye Matrix; You lost my loyalty.

No, I do not recommend this product.

We are so incredibly sorry to have let you down. Being a loyal part of our Matrix family for over a decade means the world to us, and it breaks our hearts that the new jojoba formula doesn't provide the deep moisture, slip, and bounce your hair loved. We hear you loud and clear, and we are sharing your feedback about keeping both options directly with our team.

Not too heavy and leaves hair smooth

3 months ago
Very light conditioner but great at keeping my hair smooth. My hair feels so soft even after just rinsing it. Smells just like the hair mask and it lingers post-shower as well. The only downside for me is that I have very long hair so I basically used up half the bottle in one week. Unfortunately because of how much conditioner I would use I wouldn’t have this product in my budget for repurchasing but I still recommend it since it performs really well even at day 2 hair.

Smooths frizz, adds shine, and leaves hair soft without weighing it down.

This conditioner leaves my hair feeling soft, smooth, and easy to manage. It rinses out clean without leaving any heavy residue and helps reduce frizz while adding noticeable shine. My hair feels hydrated and looks healthier after each use.

Frizz fighter

Wow! This Matrix smoothie mask is amazing! The smell was wonderful but not overpowering. The formula was easy to apply to my hair and rinsed easily. It helped with the frizz of my hair, and made my long hair easy to brush after my shower. My hair feels clean and soft, and I'm able to use less products in my hair for frizzyness.

This conditioner is a smoothing conditioner and good for frizzy hair. With the same ingredients like jojoba oil and oleic acid to balance fiber moisture in both high and low humidity.
