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 a little over 2 months, and I've noticed increased strength, volume and length in my hair as well as an impressive amount of new growth. I recommend this serum to anyone experiencing hair loss/thinning.

This is positively the best serum I have ever used for my thinning hair! When I ran out I re-ordered with expedited shipping. My order got lost by FedEx and I was almost in daily contact with customer service because I wanted to resume my applications asap. I received a replacement order and now I can return to using this awesome product. I am an African American woman and this serum has grown back my hair better than any of the oils I have used in the past that were described to be formulated for my hair type. I will not run out of this product again.

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 extremely fried to the point where I was considering getting a keratin treatment. I just noticed recently that my hair lays so much better and all the little flyaways around my part are laying down now. After massaging the serum into my scalp I brush the area where I apply it, so I think some of the serum works its way down my strands and is making all of my hair stronger. That alone is priceless for me, so I'll definitely be continuing.

I have gotten quicker and better results with PowerCycle than any other products I have tried for my thinning hair. I am so pleased with what I'm seeing and ordering my second bottle before I run out.
