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 would buy again
It has stopped hair fall out and it is easy to use. I just can't afford it his continuously will wait for another coupon from Ulta. Good product I see growth around my edges.
Didn´t work :(
After finishing one bottle of PowerCycle Scalp Treatment Serum, I found it did absolutely nothing for me. No new hair growth, not even a change in texture — no improvement at all.
It stopped my fallout!
Definitely surprised at how fast I'm seeing results. I'll update on my final results.
Yay, Powercycle is in Ulta now!
I started using this a few months ago when I saw it on the Today show. As I'm aging, my hair is getting much thinner to the point I was wearing hats. I started using this and after a few months, see a REAL difference. Highly recommend

I am a mature menopausal woman using Nutrafol for almost 2 months now. I am still waiting for results to happen and am hopeful. My cousin has used this and her hair is amazing.
