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.

This product is even better than they claim. My hair has become thin from years of being on thyroid medication. Not only does this product make my hair thicker, it also makes it more manageable, doesn't make it heavy or dirty at all and allows me to go an extra day or two between washes. Love it!!!!
Dare I say it, this stuff works

Having tried so many products, imagine my surprise that this one actually works. It hasn't been a month, and yet I see new hair and fullness. Thank you and you have won a fan forever.

I def notice less hair loss every time I shampoo my hair. It has been two weeks since I started using the power cycle. I massage my scalp after applying it for better blood circulation and absorption. I will have to keep using it to see further results at the moment.
So far, so-so

I've been using this about 2 weeks; I know it's still too soon to tell if it's working. However, I like that the consistency is thick. Other serums I've used are thin and run off onto my face which seems wasteful. It's also easier to concentrate in certain areas. The downside is that I have dark hair, so sometimes it leaves a white residue. The packaging also doesn't seem eco friendly, so I hope they develop something more sustainable for refills.
