HELP - Smoothing color-treated hair
11 years ago
I love the smoothing effect of this product. HOWEVER..... it removes the color (from hair dye) after washing my hair a few times. I wish that the company created a product which smoothed hair for those of us who colored our hair.

Absolutely the worst shampoo and conditioner I have ever used. My hair is dry and feels sticky. I honestly think drug store shampoos and conditioners are better. Wasted $100 on buying 2 liters. Will never buy anything Matrix again!!!

We are very sorry to hear about your experience. It is incredibly frustrating to invest in professional products only to have them leave your hair feeling dry and sticky.
We recommend checking the return policy of your retailer, as many authorized sellers offer satisfaction guarantees even for opened products. Additionally, try a clarifying wash to help remove the sticky residue. Your feedback is valuable to us, and we apologize that these products did not meet your expectations.

Absolutely LOVE!

So glad I found this shampoo. With the conditioner and mask as well, it’s even more effective, but even on its own, I love it. It can be hard to find moisturizing/smoothing shampoo that doesn’t weigh my hair down, and I don’t have that problem with this. Smells great, lathers nicely, and rinses easily.

One of my favorite shampoo

I love this Matrix smoothing shampoo. It has one of the most pleasant scent. The texture is creamy and make hair, my scalp feels so clean and fresh. Combing is so easy and quick since my hair becomes so soft and smooth after using this shampoo. I highly recommend this to everyone.

Sad and disappointed.
7 days ago
I used Matrix sleek and smooth down shampoo and conditioner for over 10 years and I loved it until you all decided to change the formula for the shampoo and conditioner. Recently I bought both shampoo and conditioner at Ulta and noticed that it was a different color but two it left my hair very stringy and dirty. I'm very sad and upset because now I have to find another shampoo and conditioner. I will never use these two products again. You just lost a customer.
No, I do not recommend this product.

The goat for a curly girl
9 days ago
OK, the suds alone screams luxury. As a hairstylist, I’m huge on the cleansing factors of a shampoo. This checks every box for me. You can feel the moisture and the frizz reduction/sleek start to your styling at your first shampoo. If you check out my photo, you can see how shiny my hair is after air drying with zero product put into it. Even if you don’t have curly hair, you know this is bananas.

After using it past few weeks, I love this shampoo. It cleans well without stripping too much moisture. My hair feels soft, slightly smoother after wash. Good basic shampoo but I highly recommend use with combo conditioner/ mask for best result.

Smoothing anti frizz shampoo!
9 days ago
I received this product in exchange for my honest review. This product is meant to be the first step before the mask and conditioner. 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!!!

Finally a good moisturizing shampoo with no residu
9 days ago
This shampoo is also tied for second out of the three products I got in my package from Matrix. It helps my hair feel frizz free and soft after using it with the conditioner and/or smoothie mask :)
Often, shampoos can leave my hair feeling dry even even if they don’t claim to be clarifying or for oily hair, (etc). I’ve especially been dealing with dry hair after lots of recent trips to the beach and swims in the ocean. This shampoo makes me feel better about keeping my hair healthy after doing these fun things, I don’t want to have to worry about drying my hair out when I’m having fun at the beach. Love the jojoba in it, it makes my hair feel rejuvenated and full of nutrients. Love the smell, love how well it cleans my hair without drying it, and just love the results. No problems with residue. Matrix has a new customer in me!

Great Shampoo 🧡
10 days ago
I received this shampoo 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 shampoo claims to be a smoothing shampoo 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 and makes your hair feel clean and looks shiny! I would recommend if you have frizzy hair! ✨

I love all Matrix products so I was super excited to try out the Mega Sleek Smoothing Shampoo! This shampoo for sure has become a new favorite for so many reasons! I love how good this shampoo lathers, rinses out, smells and it leaves my hair looking/feeling amazing! Just after shampooing I can notice a difference in my hair already.. less tangled, more smooth and soft plus leaves my hair smelling good all day long! Love this shampoo paired with the conditioner and mask!

Keeps my hair looking polished
11 days ago
The first thing I noticed was the lather. It foams quickly without needing a ton of product. It definitely is a good cleanse before using conditioner. My hair feels noticeably softer and when I rinse it out, it doesn’t leave my hair tangled. The scent is clean and not overwhelming. Where it stands out the most is the shine. My hair looks so polished after I dry it. It does a great job of taming my frizz and I don’t have to work as hard with my heat tools to get my hair to do what I want it to do.

We are sorry the Matrix Mega Sleek range didn't work for you. While great for smoothing, its specific formula may not have matched your hair's needs, or long-term use may have caused build-up that blocked moisture.

It's going to depend on your hair
13 days ago
So there is a lot to like about this shampoo for like 3/4 of my hair. That would be the top layer and first texture that I have. It does a fantastic job of dealing with flyaways and new growth. The challenge I'm having is the other 1/4 of my hair that is a different (more coarse and wavy bit of hair that likes to hang on to oil). That part is a challenge. Since I prefer to wash my hair every other day, this batch of hair that wants to cling to the oil in this shampoo for dear life, is driving me mad.
Great product, great scent, easy to use bottle and perfect for 3/4 of my hair... It's that other 1/4 that makes me sad to sad it's not the right product for me. The product rinses great - but if your hair loves oil? May not be the right option for you either.

Leaves hair manageable, sleek, fragrant, and frizz
14 days ago
Matrix Mega Sleek Smoothing Shampoo really went far above my expectations for shampoo. I have unruly, frizzy hair that easily tangles, so it's been hard to find anything that works. My first impression when I opened the cap was that it had the most captivating, delicious scent, and I was so excited for my hair to smell that way. It has a fresh and slightly fruity scent with notes of shea butter and light citrus, like a sweet, tropical aroma, but it isn't overpowering; it's just right.
This shampoo has really great slip to it, which helps detangle my wavy hair, as well as keep it hydrated and manageable while washing. It lathers up like a dream and makes my hair look so clean and fresh. It has Jojoba Oil, which locks humidity out, and Oleic Acid, which restores essential moisture...and my hair desperately needs both of those things to keep my hair from being unruly and dry.
My hair feels manageable, looks sleek, smells good, and is less frizzy. Highly recommend.

It’s the ideal first step for frizz free hair especially if you have fine hair that easily loses its volume. It cleanses really well to remove residue and buildup, yet it’s gentle enough for the strands to feel nourished. I love using the conditioner after for extra hydration and smooth finish for styling.

The Sleek Smoothing Shampoo has been amazing for taming my hair. It gently cleanses without drying it out, and from the first wash, I noticed my hair felt smoother and more controlled. It really helps reduce frizz and leaves my hair looking sleek, shiny, and healthy. My hair feels soft and silky even before I style it, which is a huge plus.

A good shampoo for soft hair
14 days ago
I received Matrix Mega Sleek Smoothing Shampoo for free from Influenster and Matrix in exchange for my honest review.
This shampoo bottle uses a snap lid to dispense but at least the bottle is skinny for an easier grip to squeeze the shampoo out. The shampoo smells sweet which I assume is the jojoba oil and it has a light yellowish orange tint to it. The consistency is a bit more liquid and it foamed well enough to wash my curly hair with a little bit of scent left after rinsing. It did leave my hair soft but not much difference on the frizz part.

I’ve been using the Matrix Mega Sleek Smoothing Shampoo and I like how it cleans my hair without making it feel dry or stripped. It does a good job removing buildup while still keeping my hair soft, which is key for me when dealing with frizz.
After washing, my hair already feels smoother and more manageable, especially in humid weather.
Also, the scent is really nice — it has a warm, slightly sweet salted caramel and pistachio vibe that makes the whole experience feel more elevated.

My new daily favorite shampoo

This shampoo is a great every day option for taming frizz and leave hair feeling clean, soft, and hydrated. Its formula, with enriched shea butter and oils, help smooth my hair and protect against humidity while adding shine. It clean my hair well without weighing hair down, though it might feel slightly moisturizing for very oily hair. Overall, its a solid choice for anyone who looking to control frizz and maintain a shining look for their hair.

Fine hair, prevents frizz in PNW
15 days ago
I’ve tried a lot of anti frizz shampoos and this one stands out to me for several reasons.
I love that it cleans my hair and scalp well without drying it out and giving me a squeaky clean feeling.
I have fine hair and this shampoo doesn’t leave my hair weighed down. In fact, I love how my hair looks whether I air dry or blow dry my hair. My frizz is definitely controlled. Used with the full product line, I’ve found that my hair can stand up to rainy humid PNW weather.
The formula itself has a nice thicker texture for a shampoo. It lathers really well and smells fantastic. It’s kind of a warm and sweet caramel scent.
