Description
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.
Promotes a Balanced, Nourished Scalp Environment
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.
Supports Scalp Clarity & Oil Control for Follicle Comfort
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.
How to use
Step 1: Apply to wet hair and lather. Cover scalp entirely. Wait 30 seconds to 1 minute before rinsing completely.
Step 2: Reapply to wet hair and lather. Massage scalp carefully. Focus on areas where you want to promote hair regrowth. Wait 3-5 minutes before rinsing completely.

Understanding The Science
A deeper clean, by design. HairStem™ Peptide Shampoo delivers.
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.
Zone 1TM
Hormonal Hair LossDHT is quietly shrinking your follicles.
Zone 2TM
Nutritional Hair LossYour follicles are starving for nutrients.
Zone 3TM
Inflammatory Hair LossScalp irritation blocks the growth cycle.
Zone 1™ · Hormonal
Your follicles are shrinking. And you don't know it.
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.
83%Reported and noticed hair regrowth.¹
Zone 2™ · Nutritional
Your follicles are starving. And you don't know it.
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.
85%Reported a reduction in shedding.¹
Zone 3™ · Inflammatory
Your follicles are irritated. And you don't know it.
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.

Customer Reviews
Overall rating: 4.4 / 5 from 25 reviews.
I absolutely love this shampoo. Noticed a difference in shedding after first wash
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.
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.

“I was losing confidence along with my hair, but after a few months on the Advanced Trichology routine, I
started seeing new growth. My before-and-after photos still surprise me.”
“My shedding slowed down first, then I noticed baby hairs coming in. It’s the first time in years I feel
hopeful about my hair.”
“I used to avoid bright lighting because my scalp showed so much. Now my hair looks fuller and healthier,
and friends keep asking what I changed.”
“I followed the plan exactly and the results were worth it. My hair feels stronger, my part looks smaller,
and I finally see real regrowth.”
“I bought the products out of desperation, but they exceeded my expectations. My hair is thicker, my scalp
feels better, and my confidence is up.”
“I could see my hair thinning in photos, which was heartbreaking. After sticking with Advanced Trichology
for a few months, the change has been dramatic.”
“My stylist noticed the improvement before I did. She said my hair looked fuller and healthier — and now I can see the difference in every picture.”
“I wasn’t expecting fast results, but consistency really paid off. My hair is growing again, and my scalp isn’t irritated anymore.”
“The transformation has been incredible. I went from visible thinning to a fuller head of hair, and I’m more confident going out without hats.”
“I was skeptical because I’d tried so many things, but this is the first routine that made a visible difference. My hair looks fuller and feels healthier than it has in years.”
“I used to dread washing my hair because of how much I’d lose. Now the shedding has slowed down, and I’m actually seeing new growth in the spots that worried me the most.”
“I didn’t expect my before-and-after photos to look this different. My hair feels thicker, my part has filled in, and I finally feel like myself again.”
“My confidence took a hit when my hair started thinning, but sticking with the plan changed everything. My scalp isn’t showing anymore, and my hair looks strong and full.”
“I had patchy thinning around my temples, and now those areas are filling back in. It feels amazing to finally see progress.”
“My thinning was getting worse every month, and it really scared me. After staying consistent, I started seeing small improvements that turned into big ones.”
“I kept seeing progress month after month — less shedding, healthier strands, and now actual regrowth. I’m honestly thrilled with the results.”
William Gaunitz, WTS, spent over two decades studying why hair falls out — and more importantly, how to stop it. NutraM Scalp Serum is the result of that research: a targeted topical formula designed to block DHT and restore scalp health naturally.
