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...

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 expected. I started using it again and after 1 week, I noticed the texture of my hair changed and I didn't like it. It became brittle, not smooth, tangled, and dry. I didn't change my shampoo or conditioner. I stopped using for 1 week and my texture returned prior to using this. I contacted customer service (concierge) and was out of the 30 day window. Note: the 30 day window is based on your purchase date not when you receive the product. I understand this but when you use a health product, many times you need those 30 days. I asked if I could provide a doctor's note/surgery statement and have never heard back.
Seeing results!

I have been thinning and receding lately and looking for a solution. I wanted something scientific and with no scary side effects that I have heard from others using minoxidil. I have been using this every night for a few weeks now and I def feel fuller. I'm excited to see with more time what this stuff can do! Would recommend trying

This product is easy to use. It has a Pleasant feel and aroma. Even though I have not seen any real results, I will continue to use for a longer stretch before I reevaluate.
