Best Ever!

11 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.

Not the end all be all of conditioners. It performs well above drugstore brands, but for a salon conditioner, it’s a bit lackluster. I think there are better salon options out there, at the same price point.

Love this conditioner. A little goes a long way! It's a thick formula and rubs into your hair so nice. Rinses out so clean, leaving the hair so soft. It smells great too! Worked great on my wavy hair and also on my girls curly hair.

This is my new favorite conditioner! It left my hair insanely shiny and smooth immediately. I just wish the bottle was larger because I will go through this fast. I love how you see the effects literally as soon as you apply it. It brushes easily and just feels oh so hydrated. Highly recommend and will be purchasing again and again!

I absolutely love this line from matrix! The scent is amazing and so are the results. My hair is always so soft since using this. I am prone to tangles so this really keeps keep my hair soft and non frizzy after washing. The only downside is the bottles are pretty flimsy so the caps break easily. Other than that I am obsessed!

Smells so good, a citrusy smell that leaves your hair feeling smooth. I used it after the shampoo and left it in for a min or two and rinsed well. Left hair to air dry and it was smooth, frizz tamed, and smelling amazing. Didn’t dry out my scalp, no weird residue, and consistency is nice and thick. Not much is required for shoulder length hair.

This conditioner was a welcome part of the three-step system. Without the mask, I feel my results are less noticeable, but this still certainly makes my hair feel softer, even if it doesn’t do as much for frizz once dry. It also smells great!

Leaves my hair super soft & hydrated!

I received this product in exchange for my honest review. This product is meant to be applied after shampoo for up to one minute before rinsing off. The product comes out thick, but lathers well into hair. Once rinsed out, my hair feels super soft and hydrated! Once dry, my hair appears less frizzy. I can’t wait to continue weekly use of this product and see if it helps long term with hair breakage! I would definitely recommend!!!

Luscious, frizz free results!

This is tied for second with the shampoo out of the package I received from Matrix. My first favorite product was the smoothie hair mask!! This conditioner is lovely and supports the same results as the deep conditioning mask aims for, especially when used in the same routine ;). The product really does help manage my frizz and leaves my hair silky and soft, and I just moved to Georgia where the humidity is much higher! The smell is delicious and the product just feels rich overall. Thank you, Matrix! I will purchase more of this after I finish the bottle — I’ve found my new brand for conditioner. Photos show the product and my hair after using it along with the shampoo and deep mask.

Great Conditioner 🧡

I received this conditioner from Influenster in exchange for my honest review. First, I love the packaging! The colors are beautiful and the container itself is super cute and durable. The conditioner claims to be a smoothing conditioner for frizzy hair. I love the ingredients of oleic acid (which restores essential moisture) and jojoba oil (which locks humidity out). It has a fresh and slightly fruity scent with notes of shea butter and light citrus but nothing overpowering. It lathers nicely, makes your hair feel clean and makes your hair shiny. I would definitely recommend if you have frizzy hair! ✨

There is a lot to like here

18 days ago
There is a lot to like about this conditioner! And it's honestly great for about 3/4 of my hair. It's the last 1/4 that is a bit wavy/loves to collect oil that is causing an issue. This does a great job of adding shine to the hair. It doesn't dry you out and it assists with detangling (I only use this on the bottom 1/3 of my hair) but that part of my hair that has a different texture holds on to the oils in the product and it forces me to wash my hair more than I want. So if you have a single type of hair where you are dealing with flyaways and are looking for some frizz taming, this is a great option for you that smells good, has a good package and is easy to use.

Goodbye Frizz, Hello Mega Sleek.

18 days ago
Matrix Mega Sleek Smoothing conditioner isn't just a gimmicky name; it's the reality of the results of this conditioner. When I saw the bottle's packaging, I was instantly drawn to it with its bold, unique font and colors you can't miss when you walk down the hair aisle. I knew I was in for a treat when I cracked open the bottle and out came a heavenly tropical scent with a touch of vanilla, with the Jojoba Oil coming through as well. I knew my hair was going to smell amazing, and it does, and the scent lasts all day. The consistency is creamy and thick but still easy to spread. It soaks in and easily coats every strand. It says to wait a few minutes before you wash it out, but if you want it to be a little bit more of a treatment, I like to leave it for a full ten minutes. It leaves my hair smooth, shiny, and tangle-free. The oleic acid and Jojoba humidity-proof my hair, leaving it frizz-free no matter the weather. For someone like myself with coarse, wavy hair, this conditioner is a lifesaver, and I absolutely love it. I highly recommend it, and it will be a staple in my shower permanently.

Silky smooth conditioner

19 days ago
As someone with thick frizzy hair, I love this conditioner. The consistency is thick and creamy but not hard to work through. As soon as I apply it, it creates a silky slip making detangling much easier. It makes my hair softer without feeling waxy. Shine-wise, I did notice a slight improvement but nothing crazy. It made my hair look natural looking and less dull. Rinsing was super easy. My hair feels hydrated and not weighed down. Overall, it’s a well balanced conditioner.

A good conditioner that leaves your hair soft.

22 days ago
I recieved Matrix Mega Sleek Smoothing Conditioner for free from Influenster and Matrix in exchange for my honest review. This conditioner comes in a snap lid dispense bottle which you squeeze out although it being skinny helps with your grip. The conditioner is a thick consistency with a light yellow orangish tint to it. It smells sweet which I assume is the jojoba oil and very little scent is left on my hair after rinsing off. I leave the conditioner on my curly for a few minutes before washing off. So far my hair is left soft but I haven't noticed much of a difference with my frizz though.

The Matrix Mega Sleek Smoothing Conditioner is honestly one of my favorite steps. It makes detangling so much easier and leaves my hair feeling instantly softer and smoother. It helps control frizz without making my hair feel heavy, and I’ve noticed my hair looks more polished after styling. The scent is also a plus — it’s warm, slightly sweet, and makes the routine feel more luxurious.

Hair holds up to humidity

22 days ago
Rich and creamy texture, feels instantly hydrating without being too heavy. This is probably the best anti frizz conditioner I’ve used for my fine hair in a humid environment. I notice immediately how much easier to manage my hair becomes after using it. It detangles easily after the shower and it looks more polished and smoother when dry. It keeps frizz under control and makes styling easier and helps blowouts last longer in the humid PNW. I love that it doesn’t weigh my hair down or leave any residue. It washes out easily in the shower and leaves me with smooth manageable hair. The packaging is convenient and easy to use. It also smells great! A warm sweet caramel scent. I love using this with the complete line of products to help prevent frizz better.
