Absolutely cannot live without this product! I have curly hair and straighten it all the time and this is the only product that keeps my hair looking silky and smooth!
I put about a quarter size in before i straighten as i have long hair and it turns our perfect! Careful to not use too much as can look greasy.

Ma coiffeuse m'a fait découvrir ce produit il y a quelques années et je l'utilise encore. Parfait pour contrôler les frisottis, j'en applique chaque fois qu'il y a beaucoup d'humidité à l'extérieur et ça sent trop bon!!!

Makes my hair sooo soft, and not overly greasy. You only need a small dime sized dallop so it asts forever too! And I just realised you can use on skin as Well! Helps blend my hair into my extensions perfectly.

Excellent shampooing pour les cheveux frisés il a fait des merveilles pour réparer les pointes cassées de mes cheveux j'utilise aussi le revitalisant et l'huile à cheveux, merveilleux produit!

I use this serum every time I get out of the shower. I dye my hair a lot, and this serum leaves my hair feeling silky smooth and with a ton of shine! Plus it smells amazing. Cannot live without it.

Great quality and nice smelling. It is not my go to all of the time but I always have some kicking around. It keeps my hair super smooth and keeps it from getting frizzy. A little expensive but you can sometimes find it on sale.

This product leaves my hair smelling amazing and so so soft. I love the fact that it doesn't leave your hair greasy after, also you don't need a lot, just a pea size drop and your good to go (hair hair is pretty long). 110% addicted to this product!

I like this product and always feel like i just left the salon when I use it. I love how smooth and shiny it makes my hair. I find it a bit tricky to use the right amount though, as it is very easy to use too much. I do find the product lasts long and will continue to repurchase in the future.

Biosilk smells really good and leaves your hair feeling soft and silky as promised. But I have really long hair and I like using a lot of product, and as much as I want when I shampoo and condition my hair. I find this to be a bit too expensive for the small bottles, I go through them too quickly.

I have been using this product for more than a decade! You don't need a lot to make your hair look silky smooth. A little goes a long way for the product! I love the smell and this product is singlehandedly my magic hair serum.
