Well I definitely approve of this shampoo! Any product with keratin is usually good, and this one is for sure. My hair was left clean, smooth and looking a lot healthier than it did prior to use. I followed it up with a leave in conditioner and voila! Great overall

I didn't find that this shampoo worked any different than any other shampoo I've tried before. I have curly hair so I thought it might tame it and take out the frizz but it didn't do anything more than any other shampoo i've tried before.

I found that the price was quite expensive for how much you get. But the product itself is very good. I have extremely frizzy hair and it helped me get through a hot day

Definitely one of my favourite shampoos! I had really damaged and fried hair, but this shampoo followed by the conditioner, helped A LOT. I've always liked TRESemme shampoos, but this one is the best. I definitely think it's salon quality, and I will continue to use it!

My brother uses this product and it was in the shower so I gave it a try. It smells good and I had a lot of lather, which I find hard to find in a lot of shampoos lately. My hair felt smooth and bouncy afterwards. So I had a positive experience.

Absolutely amazing! I have tried other products with TRESemmé and have yet to be let down. Comparable to salon quality in every way, and at a less intense shock to your pocket book. My hair is noticably smoother, and feels fresh after every wash with a very gentle and pleasing scent to your hair.
With having thick, long hair, this shampoo gives me the ability to manipulate and tame the "beast" that is my head, with ease and virtually painlessly. Will have to add this one to my regular rotation for sure!

I still use this product presently! About 3 times a week I put it on my hair after shampooing and leave it on for atleast 2 minutes before I wash it off it leaves my hair smooth and hydrated! I had really coarse hair with dry sculpt this product helped my hair look and feel alive again and it's affordable!

Worked pretty good in my hair when I used it. It definitely did its job in leaving my hair smooth and fresh. I like to use twice during my shower for extra smotthness

I eagerly tried out the 7 Day Keratin Smooth Shampoo as part of the complete system (Shampoo, Conditioner, and Heat-Activated Treatment) when it first came on the market a couple of years ago. I cannot attest to the fact that my hair stayed smooth for 7 days as I am a daily washer (I know, I know...) However, I can attest to the fact that my hair indeed felt very smooth and silky after using the products - and it smelled fantastic! Also, the price was a pretty good value for the amount of shampoo considering how long it would probably last under ideal conditions. I would recommend this product and line in general.

TreSemme is one of the only drug store shampoo brands I will purchase often. I find it works well and you get a good value for your money. I really enjoy the keratin line as I find it really makes my hair soft and smooth. My hair is thin but I have a lot of hair so it can get really frizzy so I need a shampoo that can tame that and I find this with the conditioner work great!
