    good stuff

    I think this has helped my shedding slow down--but I have trouble with the pipette as I have arthritis in my hands. I'm getting the 3% which might be easier to be consistent. It has helped calm down my scalp itchiness though some of that may have been the medicines I have had to take. My stylist has noticed more new growth though that is hard for me to feel. Most of my thinning is crown and sides in a semicircular pattern, from medical issues and stress. Looking forward to the new stuff.

    Thicker, fuller hair achieved

    I'd previously tried Stem Cell Scalp Serum, but was not consistent in my use of it. This time I have been very consistent at applying it almost every day for approximately 9 weeks, and the difference is noticeable. My wife has even commented that an area that was thinning at the crown of my head and the mid-frontal point / Widow’s Peak is noticeably fuller. I can also feel that my normally fine hair feels thicker with more body. I use the entire Act + Acre system including the shampoo and conditioner.

    Highly recommended

    I’ve been really happy with this serum! I’m noticing lots of new hairs growing, and it doesn’t make my scalp oily at all. If anything, my scalp feels less oily, so I can go longer between washes. My hair looks amazing!

    This stuff works!

    My entire life, I’ve had full thick hair, but was so distraught when my hair started falling out after a 90 lb weight loss (not on glp-1). I decided to try this product and loved the formula. Not oily or sticky at all. I was extremely consistent and used it every single night and also washed my hair 1 extra time during the week because I heard that helps. Those were the only 2 things I did and it helped so much! After 3 months of use my hair is noticeably more dense and my hair stopped falling out in clumps. Super happy and thankful for this product!

    I really liked the product, but it’s out of my budget for now. I wasn’t able to use it long enough to see results so i can’t give a real review.
