    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.

    Scalp Relief Cooling Serum

    I have been using the Scalp Cooling Serum with a while now and generally find it good. Sometimes I pair it with Moogoo Scalp Cream for a more effective relief. I have psoriasis on my scalp.

    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.

    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.
