Initialiste Advanced Scalp and Hair Concentrate | Adds shine and softness, strengthens, reduces breakage

I could not swear by this product more. For a long time I could tell my hair was getting thinner but I couldn’t find anything to stop it. I started applying this and while yes it took time - my hairline has visibly moved forward. I have baby hairs again peaking out at the edges. My hair is overall thicker and stronger. Truly incredible!

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 been having an on and off issue with hair thinning. I started looking for help and had read positive comments about this product. Although it is early on in the process, I do think my scalp is doing better. Plus I massage this in the front and top part of my hair before I go to bed. Comb through my hair and in morning, it is as though I did not put it in my hair. I am trying to say it does not disturb my hairstyle by using before bedtime. Good purchase for me.

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.

I wasn't sure what to expect as this was called a serum. I thought it would have some type of oil property to it but it does not. It does make my hair very soft but later in the day my hair becomes very static. I don't know if it helps with hair growth, I haven't used it long enough.

I love this concentrate. Been using it on and off for over 10 years. It regenerates and revitalizes hair. About 10 years ago I was losing a lot of hair and I started using this concentrate and it helped my hair regrow. Smells really good too.

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.

For me, it's doing the job. Black hair care, not greasy, great smell. I I remember years ago Oprah said she uses this brand.

Se nota más fuerte el cabello cuando terminas el tratamiento.

I finished one bottle and i dont see any changes. Not worth for the high money

Erst einmal vorab, ich hab mir das Produkt im November 2015 bestellt und schreib zum Glück erst jetzt (März 16) die Bewertung. Zum Glück deshalb: Nach 8 Wochen regelmäßigen Anwendungen hab ich noch nicht einmal eine minimale Verbesserung bemerkt, war schon drauf und dran mit der Anwendung aufzuhören (hilft ja sowieso nicht dachte ich mir) wiederum wollte ich meinen inneren Schweibehunde nicht gewinnen lassen und machte weiter bis jetzt. Und sie da, erster Erfolg, es wachsen ganz feine Haare am Ansatz. Es dauert wirklich seine Zeit aber es bringt was, allerdings muss ich dazu sagen das ich normal dichte Haare, und schulterlang hab und es einfach ausprobieren wollen.

E' un prodotto meraviglioso..lascia i capelli morbidi corposi e profumatissimi..lo applico la sera prima di andare a letto sulla lunghezza dei capelli e li rende davvero rigenerati ..la consegna è stata puntualissima .

Je viens modifier mon commentaire négatif laissé quelques semaines après avoir commencé à utiliser ce produit.. Il faut le reconnaître quand on a tort, et là, j'avoue que je me suis précipitée dans mon évaluation. Ce produit est vraiment top, j'ai des repousses assez importantes. Mes baby hair forment presque une frange après 3 mois et demi d'utilisation - sachant que j'en suis encore à mon premier flacon (oui je compte en racheter). Le conseil le plus important : il faut persévérer. Continuez à l'appliquer (à chaque fois que vous vous lavez les cheveux, juste après les avoir essorés) même si vous ne voyez toujours pas de résultats. Ça prend entre 3 et 4 mois pour voir sa masse capillaire se densifier.
