Kerastase claims hair shed is reduced after 6 weeks of use and for me hitting the 5th week was amazing, my hair shed literally HALVED.
And during the 3-month treatment, my hair grew a lot, I was very surprised that it wasn't \"just\" [marketing].
I stopped the serum almost 2 weeks ago and less panicked about going bald now. After it made me lose half of [my hair].
I've bought it several times (the French version with aminexil) and it is very effective on me. I lose much less hair!
