The foundation
Buildup clears and the scalp feels clean. Shedding in the shower starts to slow.
The shift
Shedding reduces significantly. Hair feels thicker between washes and holds volume longer.
The result
Less shedding and the first signs of new growth. 83% noticed hair regrowth at six months.¹
Individual results will vary based on multiple factors, including but not limited individual biology, consistency and duration of use, and the severity and cause of hair loss.
Understanding The Science
Every wash is a reset. HairStem Shampoo makes it count.
Hair loss isn't random — it maps to specific zones on the scalp, each with a distinct root cause. HairStem 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.

looks and feels good, as far as what it does - who knows
This shampoo is AWESOME! So saturated with all the good nutrients that our hair and scalp needs. After 6 months of use on their program, I am very pleased with the fullness and texture of my "new hair!" Thank you.
The DHT Blocking shampoo has really improved my hair fall. It cleanses my scalp thoroughly without causing any dryness or flaking. It conditions my hair, leaving it soft and hydrated. It does exactly what it says it does! I would recommend it to anyone experiencing hair loss.
The shampoo makes my hair feel very clean (with the two recommended applications). My hair doesn’t tangle at all with this shampoo which means I barely need to comb it out before drying it. The scent is very pleasant.

I have been using the shampoo for a month and a half. It is too harsh for me. After washing out the shampoo, the hair is like tow. It has to be softened with other means.
I have not seen any results yet - everything is still the same as before. But I hope
I’ve been using this shampoo for a couple years and while I believe it works, my biggest issue is the inconsistency in quality. Multiple times, I’ve received bottles that are "coagulated"—thick, clumpy, like hair gel and nearly impossible to work with. I get that the brand avoids preservatives, which I respect, but the end result is frustrating.
When it's coagulated, the shampoo won’t stay in my hand—it just slides off and ends up wasted on the shower floor. Shaking the bottle or adding water doesn’t help. The texture feels off, like the oils are overly concentrated, and when I use it in that state, it actually messes up my hair—making it feel dry or unbalanced a lot more breakage feeling like straw and never continually holding moisture. That leads me to wear a hat more often, which defeats the whole purpose of using a hair growth product.
Now, every time I order a new bottle, I stress about whether it’ll arrive usable. The 'last two bottles' I got were both coagulated, which makes me question the value for the price. I wish I could say this shampoo has helped my hair overall, but with so many bad batches, it’s hard to tell. It feels like half the time I order, I get a ruined bottle'. I really hope the company improves its 'quality control', because customers shouldn’t have to gamble every time they restock or ship.
Scalp conditions were seborrheic dermatitis and mild alopecia of some sort. THIS PRODUCT HAS ELIMINATED BOTH. First use there was slight redness and tingling in the crown where my hair had thinned the most but I could tell it was a good thing given that there was little to no shedding(tingling lasted less than a minute or two) Second use there was no redness or tingling. 3 months in with weekly washes and the overall health of my hair is amazing!! It has completely eliminated my lifelong battle with dermatitis/eczema(severe dryness/sores/itchyness) and in turn allowed my hair to grow in much more supple and healthy. Ive always been able to retain length despite the scalp condition but this definitely helped my hair grow back in even healthier and fuller. Favorite thing is how clean and calm my scalp feels between washes now. Sweet relief!!!
First two pics are of thinning and redness last 3 pics show difference in thickness near part and scalp recovery.

At first I was skeptical, but for 6 weeks, along with other vitamins I have seen less hair loss! I’m very thankful my Trichologist recommended this product.
