KerastaseInitialiste Advanced Scalp and Hair Concentrate - Adds Shine and Softness, Strengthens and Reduces Breakage, Adds Shine

I have a really dry scalp with psoriasis that can flake and itch a lot but this product does wonders for me. It gives some moisture and a little body to my hair and scalp. The scent is nice. I’m allergic to a lot of hair products due to preservatives or fragrances.

Really happy so far. Thick so it feels like it stays. Scent is pleasant and underwhelming

I have been using this for over six months along with the Densifique shampoo and conditioner. My hair fallout has SIGNIFICANTLY reduced. While it’s normal for hair to fall during the day, I used to lose more than your average bear. Perimenopause/menopause really keeps a gal on her toes. So. Much. Fun! Anyhoops, I also created a vitamin dupe blend of the most popular one marketed towards women during this stage of life. The price is pretty ridiculous so I broke down the label and sourced my own from this platform. I can get a three month supply of vitamins for the price of one of the brand name. This combo of items has helped my hair situation a lot. I lose maybe 3-5 hairs in the shower whereas before I was losing 20+. I also shed way less throughout the day. Before I would find my hair everywhere. Now that isn’t the case. The Densifique shampoo is also one of the best smelling shampoos I’ve ever encountered. I will never use anything else. It’s all expensive but sometimes a girl’s gotta do what a girl’s gotta do.

UPDATE: What I thought was new growth turned out to be breakage, i.e. little hairs that were broken off. So no growth effect...!I've been using this product for just over 3 months, every second day - on my hairline around the face and also on the sides towards the back of my head as I felt that my hair (butt length) was getting thinner.I now checked and yes, there is new growth, I saw lots of hairs about 2-4 cm long. But is it the effect of this serum, or would have new growth happened anyway? There is no way to know for sure!The bottle is empty now and I'm considering buying another one...(has anybody noticed that it has a negative effect on nail varnish? I feel that my top layer which is shiny is getting dull quicker than usual, maybe I'll use plastic gloves when using it again to avoid this)

Great product!

I love this and the smell and how full it makes my hair look! So much volume! May forever go to! I am defiantly getting the shampoo and conditioner from this brand since this product is so good!

This is pricey but worth every penny! It only takes four little drops and I can’t believe the difference it’s made in the texture of my hair!

Very expensive for what you get and you don’t know what to do with it needs to have better instructions. It’s just sitting on my shelf. The bottle is pretty
