Description

Hormonal thinning needs pressure from two directions at once — internal DHT support, and a scalp kept clear and fed. This pack pairs DHT Blocker Maximum Strength with the Peptide Shampoo and Peptide Spray, delivered together every month so the routine never lapses.

Benefits

Hormonal, from both sides

DHT Blocker Maximum Strength works from the inside while the Peptide Shampoo and Peptide Spray keep the scalp clear and fed — the two halves of a hormonal protocol.

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 DHT Blocker Maximum Strength daily with a meal. Wash with HairStem™ Peptide Shampoo, then apply HairStem™ Peptide Spray to the scalp daily. Give it at least 90 days of consistent use.

What to expect

Your growth timeline.
Here's what happens.

Day 1–30
Day 31–60
Day 61–90

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

Hormonal hair loss has two fronts.
This pack works both.

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
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
Hormonal hair loss: thinning at the crown and hairline
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
Nutritional hair loss: diffuse thinning throughout
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.

89% Recommended to family and friends.¹
Inflammatory hair loss: patchy shedding across the scalp
