It works
I've only been using PowerCycle for 28 days but I've already seen some regrowth coming in. However, the thing I'm most blown away by is that the texture of my hair is changing! I have thin, brittle, porous hair that frizzes profusely and breaks easily. The last year especially, it has looked extreme...

Changed my hair texture
I have fine/thin hair and wanted to help build fullness by my crown and sides. I started using this for about 2 days but had to stop because I had Carpal Tunnel surgery. I thought I would be able to use it within the 1st week of recovery (per my doctor), but my initial recovery took longer than expe...

Not worth the $$

I honestly can't even say if this stuff would work or not because I'd have to buy numerous bottles to have enough to apply it every day for weeks! The eye dropper applicator is ridiculous! It's impossible to apply it only to your scalp without a lot of it absorbing into your hair & getting wasted. If you just have a small spot or two on your head that needs it, it might be fine, but forget it if you plan to use it on your entire scalp!
Effective but difficult consistency

Have been using the serum for a couple of months now and can definitely see results, however the consistency is goopy, and difficult to work through the scalp.

I've been using PowerCycle for about 3 months now & am noticing remarkably thicker hair especially in the crown area of my head. I just had my hair cut, my hair dresser said I've got new growth all over my head. I'm 75 years old & my hair is looking better than it has in 10 years. I will keep using this product & highly recommend to anyone with fine thinning hair.
Miracle!

Postpartum hair loss was so tough—I felt like I was losing more hair than I had left. PowerCycle completely changed that! Within weeks, my hair fall slowed, and by month three, I saw baby hairs growing back. It's safe, science-backed, and gave me my confidence back. Highly recommend it to fellow moms.
