KÉRASTASEResistance, Strengthening & Healing Serum with Heat Protection, For Over-stressed & Very Damaged Hair, With Fibra-Kap, Sérum Thérapiste, 2x15ml

Good price and I always use it for my hair. Only thing that stops if frizzing.

This serum is really good you don’t need very much product which is a good thing as the only down side is the product comes as 30ml so it is quite expensive for the amount of product you get however the extra expense is worth it if your looking for a product to treat damaged and split mid lengths and ends as this product works wonders on dehydrated hair, the hair feels silky and smooth after using the product and if your growing your hair but cannot get past that awkward length where the hair breaks this product helps with elasticity of the hair that is noticeable after a few weeks .I would purchase this product again definitely as now part of my daily hair routine. Highly recommended. Best serum I have used.

I have thin and undefined wavy hair. Sometimes I would like to use my hair with its natural waves however it is difficult to style it. i have been using resumes, moose and other styling products but most of them were too heavy on my hair and creating this sticky look. i have read the reviews about this product and i have ordered it from Amazon. I have been using this product first time and its been few weeks now.I already have fluffy soft hair and i was looking for a product with protection and volume.1st i have used it while my hair was damp and the result was incredible. I have blow-dry my hair and my hair was smooth and had a great move.(please ensure you pump the head few times to ensure both white & clear serum comes out)Second time I have used the product on dry hair it did created slightly fuzzy look but it wasn't putting me off and i have realised that i didn't pump the product correctly. After second attempt my wavy hair tun into a nicely defined curly hair.Incredible styling and protection product for light weight-thin hair.

I was introduced to this serum at my hairdressers and love it. I have blonde, fine hair (coloured), which drys out quickly, becomes brittle, and is prone to breakage- but this product helps to strengthen it. It's not cheap, but a little goes a long way- I usually use two pumps, which spread onto my medium-length hair well after hair washing (while still wet). It makes it feel silky and smells amazing!

Very nice smell, hair smells lovely after using it.

The product is great, people comment on how shiny my hair is, ive never seen my hair so silky.BUT the pump broke after a week and only the clear serum would come out. I had to dismantle the bottle and pour the clear serum into my hand and scrap the white serum out.I've seen a few other reviews say the same. It's an expensive product so the shoddy pump is disappointing.

Happy 😊

I absolutely love this product! It's a shame it's expensive but it is worth every penny! I use it after straightening my hair and you see the immediate effects of it smoothing the hair in such a beautiful way, it leaves the hair looking amazing
