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've been using PowerCycle for 2 months. I have not noticed any difference yet. I am on my second bottle and willing to see if anything happens after a few more months. The jury is still out. If no improvement after this bottle, I won't purchase again. I was really hoping this worked.
Awesome scalp serum

My hair is super thin and fine and I have been using "hair loss" shampoos and scalp treatments for years, and this PowerCycle might be the best! What I love about it the most, is how easy it is to apply! It is not runny and watery like most scalp serums; it actually feels like more like a luxurious facial serum. PowerCycle is kind of slippery and makes application to the scalp so easy and really fast, and you do not need to use much (which is good, since the serum is pricey). This serum leave my hair full, shiny and best of all....never greasy! Even if I go 2 days between washings, I am not dealing with greasy or oily scalp. I really hope SickScience does not ever discontinue this scalp serum!
