Amazing

my scalp is very dry and this helped me so much! and my hair smells really good

Awful, awful scent

I'm so terribly sad that the scent of this shampoo is so horrendous because it is a phenomenal product. However, I will not ever be able to use it with this scent. My hair is very thick and whatever scent I put on it will stay. The scent of this made me ill. It smells like an extremely potent men's cologne. I washed my hair 3 times after using it and I can still smell it. I wish they would make this hydrating shampoo in the Jourd'automne scent or the Fleur de Temps scent. I use the hair products that have the Jour d'automne scent and it's very light and clean and I love it. I have also used the Fleur de Temps body wash and it smells divine. I noticed the volumizing shampoo has the Fleur de Temps scent but I can't use volumizing products because of my hair type. Very very sad!

The texture, scent & cleansing w/out stripping my purple color off is sensational. I thought I'd never find a pro product (I am licensed managing cosmetologist) that would meet or exceed all my requirements. It's luxurious feel & color of the shampoo to begin with is a zen-like experience. Once you get that nectar on your hair & start to shampoo? Heavenly scent of patchouli fills your shower. It leaves hair hydrated & moist. It actually does what it professes to do, unlike so many other products. I adore Number 4! Psst- your man will always want to smell you, wondering what that new scent is that you are wearing!
