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.

2 stars, because I feel like the hair I have is slightly nicer? I'm I'm giving this product one more round and that's it. What sound too good to be true… often is.

Bad breakage, hair loss and some issues w/follicles. Googled a photo of my scalp with the black dots I thought were dead follicles - exosomes were suggested. SickScience/Power Cycle was one of the products in the results. For skepticism's sake I used lesser amount, inconsistently; just enough to spread the stuff around. And I think it's working. I'll be ordering a 2nd bottle to continue my experiment. Photos are LESS than 30 days apart.

The serum is not sticky, oily or smelly. I have noticed less shedding. Makes my scalp feel soothed. I hope to see further results in a month or so. I have only been using for several weeks.
Too Thick

I tried to use this product every day but the consistency is just too thick for my hair. Even when I used very little it seemed to be a lot on my scalp and weighed down my hair.
