Resistance Length Boosting Shampoo

Sooo good. My hair feels so soft and long. Smells good too

Wont buy again

Did not work for me. Pureology shampoo is waaay better than this product.

Not good for fine hair prone to grease

I bought this product but it was too heavy for my fine hair, I noticed my scalp got oily a lot quicker than usual. It made my scalp and ends imbalanced because the ends of my hair remained dry, so even though it may have grown, my hair looked terrible at the ends.

Unfortunately this product didn’t work for me at all. I was excited about it and had high hopes as I have fine long hair, but this shampoo caused even more breakage and split ends! Unbelievable!!!! :C

So good

One of my favourite kerastase products. Always repurchasing.

Gave me dandruff

Absolutely destroyed my scalp health and gave me dandruff, when i didnt have any previously. It also lathers poorly and doesnt cover the scalp well, even when i shampooed 2x

Breaking into Strength

My hair breaks on one side. the price tag almost deterred me. But I figured out if I use a cheaper shampoo then a small amount of this shampoo. It goes a long way and my heart is so much stronger.

Weekly Staple!

I love this shampoo. I only wash once a week (usually apply and rise 2x on wash day) and this keeps me cleaner for longer than any other shampoo I’ve used. I have thick, mid-length hair, and as long as I use enough product, this shampoo works wonders on me.

Yes yes yes

Definitely does what it's described to do. Definitely 10/10

Holy grail

This line of products is my holy grail. I’ve tried to find another cheaper dupe but I haven’t found it over the last 7 years. I tried 2 another lines of kerastase and was disappointed. Bye bye money

Great

My hair has oily roots but dry mids and ends, and is wavy, long, thick/coarse, frizzy and unruly. I prefer to wear it blow dried straight with the additional use of a hair straightener. My hair loves sulphates and silicones (which are both included in this shampoo). I wanted a shampoo which would effectively clean my scalp, but not strip the rest of my hair. This shampoo manages to do this, and has also stopped my hair falling out as much when I wash it. It additionally gives me an extra day between hair washes, as it seems to control the grease on my scalp. My scalp is somewhat sensitive, but this shampoo doesn't seem to irritate it. I use it with the Kerastase Discipline conditioner, and this combination (along with additional styling products) has given me smooth, shiny and manageable hair which resists frizz well. However, if I know I need my hair to be more frizz-resistant, I would use the Kerastase Discipline shampoo instead of this (although that makes my hair go greasier a lot quicker). I haven't tried the matching conditioner to this shampoo as I don't believe it would be enough to tame my hair. The shampoo is expensive, but you don't need to use as much as it's so concentrated. Overall I'm really happy with my purchase, and will most likely buy it again.

Good if used correctly!

Protein and hydration all in one. It can cause protein overload which is why you should switch between this and a cheaper shampoo or detox shampoo once in awhile. Did help with hair fallout and breakage.
