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.

New Formula Is absolutely horrible!’

9 days ago
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.

No, I do not recommend this product.

We are deeply sorry that the new Mega Sleek formula has caused instant frizz, dullness, and breakage on your hair, especially after using the original from day one and investing in two full liter bottles. We hear you and the community feedback across Reddit, Instagram, and Facebook loud and clear—this renovation missed the mark for our most devoted customers, and we are escalating your comments directly to executive leadership. We refuse to let your two liter bottles go to waste, so please contact our Matrix Consumer Care team at 1-888-777-6396 (Monday–Friday, 9:00 AM – 5:30 PM EST) so we can help you find a bond-strengthening alternative to restore your hair's health and shine.

New formula is awful.

Dedicated Matrix Mega-Sleek Conditioner user here - been buying this for YEARS. New formula is awful - doesn’t have the ‘slip’ or moisturizing quality of the old formula. Terrible.

No, I do not recommend this product.

Hey there, hair bestie! 💙 First off, thank you for being a loyal Matrix family member for years—we truly appreciate you. I hear you loud and clear about the new Mega-Sleek formula. That signature "slip" and deep moisture are everything when you're fighting frizz, so I completely understand your frustration. While I can't change the formula directly, I'd love to help you find a new routine or styling cocktail that gives you that exact smooth, sleek finish you miss. Reach out to our team directly so we can make this right for you! ✨

Disappointing

12 days ago
Like others my family and my wife’s salon have been using this product for years. This new formula is a completely different product and should be marketed as such. We miss the old formula and likely will stop using this new product. If you do decide to change back, or sell an additional product closer to the old formula we may never know. Disappointing.

No, I do not recommend this product.

New Formula is BAD - Don't waste your $

The new formula is terrible. It smells bad, the consistency is runny, and it does NOT detangle. Bring the old formula back.

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. When we transitioned to a 100% vegan formula, we replaced our rich Shea Butter base with lighter Jojoba Oil and introduced a new fragrance, but we recognize that this shift stripped away the thick slip and effortless detangling our customers loved. While the original formula has been officially discontinued, we hear your demand loud and clear and are passing your direct feedback to our product team. We want to make things right for you, so please reach out to our Matrix Consumer Care team at 1-888-777-6396 (Monday–Friday, 9:00 AM – 5:30 PM EST) so we can process a full refund voucher and help guide you to a rich, easy-detangling alternative, such as our deeply moisturizing Food For Soft line.

New Formula is Awful - Please Go Back to the Old!

27 days ago
I am so disappointed they changed this conditioner. I've been consistently using it for years, and loved everything about the old formula. It smoothed and moisturized my hair so nicely, got rid of my tangles, and I loved the scent. The new formula does NOT smooth or detangle, and the scent is horrible. PLEASE PLEASE PLEASE go back to the old formula, or I'll unfortunately have to search for a new conditioner.

No, I do not recommend this product.

Thank you for being such a loyal, consistent user of Matrix for years, and we are so truly sorry to hear how disappointed you are with the updated Mega Sleek conditioner. When we renovated the line to be 100% vegan, we replaced the original Shea Butter base with Jojoba Oil and introduced a new, warmer fragrance profile. However, we recognize that this shift stripped away the effortless slip, deep moisture, and subtle scent you relied on, leaving your hair tangled and unmanaged. While the original formula has been officially discontinued, we hear your plea loud and clear and are passing your feedback directly to our brand leadership team.

Conditioner Formula Change Horrible!

28 days ago
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. Go to Amazon and read the reviews after the change. A perfect product is now trash. Why on earth would you change something that worked so well?

These are by far my daughter’s favorite shampoo and conditioner to use. They make her hair so smooth and she said they smell heavenly!! If you are looking for a new conditioner this is definitely worth it!

No More Dry & Damaged Curls

a month ago
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. However, this conditioner gives my curls slip and moisture needed in between wash days and after shampooing. Detangling my curls this summer has been much easier!!
