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.

    After a Few Months the Results Are REAL

    This was my first time trying a scalp serum and I purchased my first bottle in Nov 2023. It's now been about 4 months and I couldn't be happier with the results. All of the baby hairs near my hair line have completely grown out to the point it looks like I got curtain bangs cut, and I did no such thing! The results of using this serum every day are truly incredible, even my hair stylist commented how the baby hairs have grown out and I actually got her using the serum as well :)

    LIFE CHANGING

    I’m on my 3rd bottle of this amazing serum. My hair has grown so fast in such little time. My middle part is a lot fuller and my hair looks so shiny. I always get asked what I’m doing and I let them know the serum I use! I recently got asked if I was wearing extensions lol. I will forever purchase this serum. No questions asked.

    Get this in your basket!

    I am in love with this growth serum, I have tried many but this one is different. It leaves your hair feeling clean and fresh still after using it, Zero greasy or heavy feeling film at the roots like many of the growth serums I have tried and I LOVE the line up of clean ingredients! Highly recommend!

    It really works!!

    I was noticing some thinning around my temple area and some shedding in the shower. I started using the Stem Cell serum every wash day, I been using the products about 6 weeks. I can see hair fuz where I was previously thinning, and very minimal shedding.
