    I’m on my 4th bottle now and I can honestly say it’s working. I had a spot of alopecia areata that really stressed me out, but after using this consistently it started filling in and now it’s barely noticeable. I’ve also been getting a bunch of baby hairs along my hairline which I didn’t expect at all. Definitely helped with regrowth and way less shedding, so I keep repurchasing.

    I’ve been using the Foin Hair Growth Serum for a few weeks and I’m honestly impressed. The built-in brush makes it super easy and mess-free to apply, and it spreads the serum really nicely across my scalp. It’s lightweight, absorbs fast, and doesn’t leave my hair greasy at all.

    My hair looks healthier and shinier, feels stronger, and I’ve definitely noticed less shedding too. Honestly a really nice addition to my routine.
