Description
Shedding often picks up in your late thirties and forties, and rarely for a single reason. This is the full five-product protocol — internal and topical — delivered on the same day every month so the routine never lapses.
Benefits
Five products, no gaps
FoliGROWTH®, DermaIron® and EFA Complete cover the nutritional, iron and fatty-acid side. The Peptide Spray works at the scalp, and Liquid Vitamin D3 sits underneath all of it.
Internal and topical, together
Supplements rebuild what's missing inside. The topical works where the follicle is. Running both is what makes this a protocol rather than a product.
One delivery, every month
Everything arrives on the same day, at the same price — so staying consistent never depends on remembering to reorder.
Trichologist-developed
Created by certified trichologist William Gaunitz, WTS. Supported by 20 years of expertise in hair growth solutions.
How to use
Take FoliGROWTH®, DermaIron® and EFA Complete daily with a meal, plus Liquid Vitamin D3 as directed. Apply HairStem™ Peptide Spray to the scalp daily. Give it at least 90 days of consistent use.

The foundation Everything starts together on day one. Shedding begins to slow.
The shift Shedding reduces significantly, and the routine starts to feel automatic.
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
Hair loss has three drivers.
Hair loss has three drivers.
This bundle covers them.
Hair loss is not random — it maps to specific zones on the scalp, each with a distinct root cause. This protocol is built to work across them rather than treating one in isolation.
Zone 1TM
Hormonal Hair Loss
DHT is quietly shrinking your follicles.
Zone 2TM
Nutritional Hair Loss
Your follicles are starving for nutrients.
Zone 3TM
Inflammatory Hair Loss
Scalp irritation blocks the growth cycle.
Zone 1™ · Hormonal
Your follicles are
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
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
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.

I've used this product for getting my hair back in shape and keeping it that way! Great product..
It works!
I have been trying and trying to get this product stopped I cannot afford them and I will get an attorney
I didn’t receive this order, please tell Advance Trichology to just credit my account, thank you
I live the product but 2 of the capsules were broken in shipment.
Decent product. Been using after wash from nizoral because it can be pretty drying to the scalp. Adds almost to much moisture even with less sprays as instructed. Makes it look more oily and flat rather then “fuller” as product describes.
I never leave reviews but, I had to come back after 2 months of using this product and let me tell you. My hair has thickened so much since I started using these supplements. I see a 95% reduction in hair shedding and my hair has grown a lot. Thanks to this company. I recommend anyone to try this product out...
Hair accelerator! Love it!
Just stared 30 days ago.
Once a day formula. As with any product like this it takes a long time to show whether it will help with hair growth. Im into my second month.
I like my hair is thicker
Good product for hair growth supplements
It works
Dirty specks floating inside. Use to be clear and golden
2 of the pills had golden liquid in the casing its stored in
Dirty liquid. Not clear and golden like it usually is
Received product today
I really like the spray for I between shampoo and conditioner
Satisfied
Love this product. Definitely seeing the results!
Recommend by my trichology being taking for 6 months and we can see progress. Very happy
I think the DHT Blocker works but I see a slowig of any new growth on top of my head in the "male pattern" area, i.e. the area of hormonally influenced thinnness. I stopped using the topical Nutra M serum- could it be that I need to continue that? Also perhaps some element in my diet missing, or stress? Anyway, still haven't seen the number of new hairs in that area.
This has really decreased the shedding and loss of hair since I started this product! I am on my second box and I am losing less and less hair. I’m excited to see the growth start soon, for I am very optimistic in this products ability to deliver exactly what my hair needed.
As a result of using a special DHT shampoo plus this DHT supplement, I have seen quite a big difference in several months of use on my hair resulting more thickness, longer and softer feel. I am very satisfied so far with this product and only continued use will definitely be rewarding....
I have seen how the DHT Blocker has filled in my scalp where previously there was no hair! This complex really works!! Thank you!! A. Utley
Love it!!! This spray gives so much volume and makes my hair so soft!!
Very happy with the product
Inconsistent liquid color lowers my confidence of quality control
It has made a huge difference in my hair’s growth and overall look and feel. Thank you for a great product!
Works great so far
Arrived on time 🙂
Hair feels different after 30 days of use. better quality of hair after 60 days. But no visual difference in the thinning hair areas.
This is much more about the shampoo vise the extra strength supplement. I use both but the dramatic increase in volume happened very shortly after I started using the shampoo. Everyone asks me what I’m using and then ask me for the company information.
Dark color and odd odor. I think it arrived rancid.
Working great to reduce shedding
Easy to take, so far been on ot 3 months, seeing some improvement, will do another 3 months.
I’ve been using this product for a couple months now and I can see some improvement in my receding hairlines.
It is very helpful.
I've experienced less loose hairs on my pillow and in the shower. It seems to me that the product is working well
