I lost a lot of hair and had to cut half of my hair to try to maybe improve the situation and even then it kept falling out, so much so that currently my head has a lot of flaws and my hair is super thin. What saved me and stopped my hair from falling out more was the Vichy Dercos shampoo, otherwise I would go bald. Nowadays, when I comb, an average of 5 to 10 hairs fall out (I make a point of counting the hairs on the brush). Another detail of this shampoo is that with very little you get a lot of foam to clean your hair (some shampoos have to use 1 liter to get a little foam). Compliment from my partner recently: "Congratulations to the brand of this shampoo"! You know why? Because he's the one who cleans the shower trap. Before he took off kilos of hairs and nowadays few hairs. Excellent shampoo!
