KÉRASTASE Initialiste Hair Serum, Hair & Scalp Treatment, Thickens, Strengthens & Prevents Damage, Adds Softness & Shine for Thin & Weakened Hair, 2.2 Fl Oz

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.

Love this serum. Really helped with hair loss. Worth of money and smells amazing. If you experience hair loss you’d better try this product!

This product has really made a difference for my thinning hair. Hair feels fuller, and is healthierI also bought the shampoo and conditioner, but not sure they make as much difference as this does

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

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!

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 lost over 100 lbs and in doing so my weight loss affected my hair and it got thin. I use to have thick hair. I heard this stuff works so I tried it about 6 months ago. I waited to give my review. It definitely improved my hair. It is getting thicker. I put it on my roots, back of head along the sides as well. You need to massage it for about 20 seconds . I use it twice a week. Not sure if I stop using the product if my hair would return to being thin again. I’m not going to chance it. I highly recommend. Just bought another bottle.

I've been using this for a few months (3 months) and I've seen no notable difference in hair growth. Smells good but waste of money, would not purchase again and would not recommend.
