Je suis ravie je peux enfin faire mes baby haïr. Je n'avais plus du tout de cheveux aux rampes et je suis juste conquise . Merci monat

Works like a charm!!

I am always sceptical when I try any product that says it will help thinning hair because they usually do not work. I have been a Monat customer for a while now and decided to give this a try. IT WORKS!! I am in my 50"s and started getting hair loss after menopause. I have tons of new growth!!! I use this with IR Clinical shampoo and conditioner. Best decision I have made for my hair.


Nigdy nie miałam tylu włosów ❤️❤️❤️wogole nie obciąża starcza na bardzo długo 🔥🔥

Still can’t believe it!

Cut my hair short for a refresh, takes forever to grow and have hair loss from medication. Have extremely fine hair that looked so good with my new cut. From 3+ years, Monat has given me the hairline I had at 18 and has helped my hair grow healthier (just ask my stylist). Enter the IR Clinical Hair Thinning Defense. In less than a month my hair grew too much (am I really saying this?). Baby hairs everywhere, length, and beauty. I can’t say enough. I absolutely love my hair and continue to be amazed at Monat’s line up of effective, responsible and healthy products! Thank you for my gorgeous hair.

My hair has needed this

Does what it says. My hair is not greasy or oily after using, feels great on my scalp, and I’m already noticing less hair loss after one week.
