Reviews

My 79 year old hair

"My 79 year old hair is "coming back to life"! It has been "blah" for a few years, looking thinner than usual, and growing very slowly. After 46 days, it has grown in length and doesn't appear quite as fine as it really is. I can't wait for my hair dresser to see it in 2 weeks."

— Helene/Kim C. (5/5)

STAPLE

"I’ve been using this spray since January and just purchased my second bottle in August, so it lasts quite a while with regular use. I use it after wash days along with a hair serum, and over time I’ve noticed my hair looking noticeably fuller and thicker. While I also take supplements and wouldn’t attribute all of my progress to one product, I appreciate that Agent Nateur creates products where I can genuinely see and feel a difference, which makes the higher price point feel worthwhile. I also love that this spray helps soothe my scalp when it feels itchy, and the scent is beautiful without being overwhelming."

— Olivia (5/5)
