Clinically proven two-step scalp system. One daily routine for thicker, fuller-looking hair.

Mornings, your scalp needs protection. Evenings, it needs to repair. The Stem Cell Scalp Serum fortifies the follicle environment to lessen the first signs of visible shedding. The 3% Stem Cell Peptide Treatment targets the look of active thinning overnight, when your scalp's renewal cycle peaks.

+ 56% less visible hair fall-out in 12 weeks + 46% improvement in the appearance of fuller, denser hair
+ Targets thinning in two phases — prevention + active treatment
+ Supports scalp hydration + follicle environment
+ Trichologist-formulated, Cold Processed® below 40°C
+ Vegan, no rinse, leave-on — both products

How to Use:

Stem Cell Scalp Serum:
On clean damp or dry hair, apply 1—2 pipettes along the hairline and part. Massage into the scalp. Do not rinse.

3% Stem Cell Peptide Treatment:
On clean, damp scalp, spray 1—2 pumps per section. Massage into the scalp. Do not rinse. Use daily for best results.

Both products can be used post-wash on wet, damp, or dry hair at any time of day — we recommend the Stem Cell Scalp Serum in the morning and the 3% Stem Cell Peptide Treatment in the evening, or layer them together (Peptide Treatment first, then Serum) at the same time of day for maximum benefit.

    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.

    I can NOT believe how well this works. I have an insane amount of new growth. I’m at the weird stage right now where I look a little crazy after almost three months, but there is no denying this stuff works!

    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!
