HairStem™ Peptide Shampoo contains bioidentical peptides – the same ones that are naturally present in the scalp – to optimize and support nutrient uptake, oxygenation, and cell renewal, creating the ideal environment for thicker, fuller looking hair. Additional nutrient-rich botanicals and herbal ingredients help reduce sebum buildup, improve follicle resilience, and promote a healthy scalp microbiome.
Copper tripeptide-1, biotinoyl tripeptide-3, and acetyl tripeptide-3 work together to support scalp renewal and follicle resilience, reinforcing the look of stronger hair at the root and supporting healthier density appearance.
Aloe vera extract, jojoba oil, and arnica flower extract help soothe scalp discomfort, support hydration, and nourish the skin at the root—creating a calm, balanced foundation for healthier-looking hair.
Tea tree oil, grapefruit seed oil, and rosemary oil refresh the scalp, reduce buildup sensation, and support a cleaner, more balanced scalp microbiome for follicle comfort and optimization.
Pro-vitamin B5 (panthenol) and hydrolyzed wheat protein condition, smooth, and reinforce hair fiber to improve resilience—supporting fuller-looking hair by minimizing breakage and fragility appearance.

Hair loss isn't random — it maps to specific zones on the scalp, each with a distinct root cause. HairStem™ Peptide Shampoo is an accelerator — it supports all three zones rather than targeting one, helping maintain the scalp environment hair needs to grow.
Testosterone can convert into DHT, which can bind to susceptible hair follicles and gradually shorten the growth cycle — leading to finer, weaker strands and visible thinning, especially at the temples and crown.
Deficiencies in key vitamins, minerals, and nutrients can disrupt the hair growth cycle, leading to increased shedding, diffuse thinning, and weaker growth. Correcting these nutritional gaps helps create the foundation follicles need to grow normally.
When the scalp becomes irritated — from stress, immune responses, or product buildup — blood flow to follicles is restricted and the growth cycle breaks down. Calming botanicals and targeted nutrients help restore a healthy scalp environment where hair can grow.

I absolutely love this shampoo. Noticed a difference in shedding after first wash
Fast shipping. I need to use it. I will know more later.
Feels very nice makes my hair feel fuller
It does nothing
Great
order arrived quickly
Great
It lathers well, but my hair is not as soft afterwards.
Tingles but haven’t noticed any changes
It’s great
Love the scent and the texture, and it makes my hair look so healthy and shiny!
The shampoo smells like Pine-Sol. You need to use a lot more shampoo to get a lather. I have gone through the is bottle in two weeks because of this. I have to shampoo everyday due to my scalp producing an excessive amount of oil. Plus the bottle of shampoo is expensive for the amount you get.
A great shampoo and the only issue I have with it is that it is too watery so you tend to go through it quicker. Besides that I like the results I'm getting.
excellent product - will buy again.
Very clean , will see as time goes on !!!
Only 1 month into the shampoo so still too early to say :)
Thank you Like it
I know the ingredients that are in the shampoo are better than any other shampoo. I have checked out others. My head feels minty fresh and very clean. The volume has doubled and makes the hair looks twice as dense. I’m off to a good start. I love that it is strong and effective yet gentle and not drying. No sulphates.
A little early to say.
Have just started using this product so it is way too soon to tell anything.
too early to tell how helpful it realy is. But I believe that it has reduced shedding
I believe the shampoo is helping me cover up my receiving hair line.
Great shampoo but probably too expensive to use on a regular basis.
Superb shampoo. Lathers very well . Highly recommend. Will purchase again.
Dandruff and hair fall has reduced. I am also using the serum and conditioner
