Rated 5 out of 5 by from Dry hair no more Typically my hair was dry and would retain an extreme amount of water the first few washes after highlights. Since switching to this line my blond hair has never been more manageable.

Rated 5 out of 5 by from Love this conditioner! I'm so happy I tried this out. My hair is thick, curly and course. My hair is colored every month with highlights and I flat iron my hair after drying so it needs deep conditioning once in awhile. i've tried the other Kerastase conditioners and while they are ok, they are usually too heavy or too light. This conditioner is just right! It absorbs quickly into my freshly washed hair and rinses nicely. Leaves my hair soft but not fly-away. This conditioner is a new staple for me!

Rated 5 out of 5 by from Really happy customer I love this line. Introduced by my stylist and I use a number of other Kérastase products but this is now my go-to. Love the fragrance, how my hair is styling following use and how my hair feels overall. My hair is naturally curly and also processed and some thinning issues at crown. My hair has vibrancy with the line.

Rated 5 out of 5 by from Best Product Line I've Ever Used for Fragile Hair Finally a conditioner that doesn't contain alcohol and protein which are terrible ingredients for baby fine, fragile hair, highlghted hair. So impressed. Hopefully this Aura Botanica product line is the end of my bad hair days! After using all the products in the Aura Botanica line, my hair is now healthy looking with great bounce and shine.

Rated 5 out of 5 by from Best conditioner I have ever used I love this conditioner, it moisturizes the hair without weighing it down and has no silicone to cause build-up. I have been using it for approximately one month and my hair gets better each time I use.

Rated 5 out of 5 by from Misunderstood A must to follow the shampoo from this line. After I shampooed my hair with the Bain Micellaire my hair was stiff and felt matted. But, once I applied the Soin Fondamental my hair felt fine again. The conditioner didn't add slip. It does however still detangle the hair well. I left it on for 10 minutes without adding any additonal Concentre Essentiel added to the conditioner. After I rinsed the conditoner I sprayed my hair with the Essence D'Eclat. I have salon finished hair. I can't wait to use it on my family so they can be amazed too. I found it to be very moisturizing for a conditioner.

Rated 5 out of 5 by from Super Shiny Hair & no frizz AURA BOTANICA Soin Fondamental is awesome! It hydrates my my natural, long, uncolored thick, coarse, wavy, thick dull hair. It leaves it extremely shiny. My hair loves to frizz and this tames it wonderful. My hair feels much lighter too. I highly recommend
