I love this brand and this line of hair products. My hair is soft, clean and dandruff free. I recommend this products

I think they’re over scented for sensitive products which is disappointing but they do smell very nice. I get on ok with them but they’re not a game changer for me (I have dermatitis on my scalp).

This is definitely and interesting product, the pre-shampoo scalp treatment definitely leaves my scalp feeling fresh and you don’t need a lot as it lathers up quite quickly. Using the duo together helps to keep my hair fresher for longer throughout the day but I have naturally oily skin / scalp and I find I have weightless clean hair after the shampoo - also my roots have a lot of volume than usual after a simple rough blow dry. I still felt the need to wash my hair the next day because I really dislike the tiniest bit of grease - however my hair is not as greasy as usual with this :) I used this shampoo for about two months to get a feel for it and that’s what I discovered. It has a masculin scent (in my opinion) like aftershave but nonetheless my bleached blonde hair felt good and not ever dried out, I’d say this is a great shampoo for those with oily roots and dry ends but isn’t an immediate fix for people with a lot of grease naturally occurring on your scalp. 

My hair feels so much cleaner since using these products.  I no longer have any product build up and I can go longer between washes. 

really love this, it’s really helped my dry flaky scalp. it doesn’t smell as nice as some of the other kerastase products but definitely works for the purpose and i will be repurchasing
