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

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.

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.

I love this Kerastase product. It does dry my scalp a bit but overall I can feel my hair getting more thick.

UPDATE: started in 2024 and now in 2025 my hair is really fuller, tons of new growth in the thinner areas. I only use it every two days after shampooing. It takes time but don’t give up.I love how much body it gives my hair. I don’t follow the directions although I do try to get some of it on my scalp. I bit pricey as all Kerastase products are but they are worth it.

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!

I have been purchasing this for years. A bottle lasts me for a long time because I don’t use it frequently since it is pricey. If you want to pamper your hair, and decrease hair shedding, go for it. It smells like heaven too. It’s not heavy on your hair and I think it’s a great addition to any hair regimen.

Very little product and hard to get out of bottle. Little bit at a time. Didn't notice any difference at all. To spend for little bit product
