Great for hair loss prevention

[This review was collected as part of a promotion.] [I received this product in exchange for my honest review] I always love the scent of kerastase. The liquid consistency makes the product easily to be absorbed by the hair and doesn’t leave any residue behind. Not sticky and my hair always look healthy and strong afterwards.

Great for hair loss and breakage

[This review was collected as part of a promotion.] [I received this product in exchange for my honest review] I have always had pretty thick hair, until my late 30’s, I started noticing more hair on the brush and in the drain in the shower. When I turned 40, it just increased. I have been using Keratase Fortifiant hair serum nightly for a few weeks now and already see some improvement in my hair’s strength and shine, plus less shedding. The serum is lightweight, absorbs easily into my scalp, is non greasy and doesn’t weigh my hair down. The scent is quite strong, but I really like it. I am very excited and optimistic to see the results with longer, continued use.
