Hair Loss Isn't A Product Problem.It's A Routine Problem.
The Protocol Fixes The Routine.
A structured, barber-built hair support system designed to support scalp health, manage early thinning, and build long-term consistency. Not a quick fix. Not a miracle product. A routine.

Understanding The Problem
Why Hair Thins. Why Routine Matters.
Most men don't lose their hair overnight. It's a gradual process, driven by DHT sensitivity, that begins long before it becomes visible. The problem isn't that people don't act — it's that they act too late, with the wrong products, without a system. That's what The Protocol is designed to change.
01 Testosterone is naturally present
Your body produces testosterone throughout your life. On its own, it doesn't cause hair loss.
02 5-Alpha Reductase Converts It to DHT
An enzyme in your scalp converts testosterone into dihydrotestosterone - DHT - a more potent androgen.
03 DHT Binds to Sensitive Follicles
In men with genetic sensitivity, DHT binds to hair follicle receptors and begins to miniaturise them over time.
04 Follicles Shrink. Growth Cycles Shorten.
As follicles miniaturise, hair grows back finer, shorter, and weaker - until the cycle stops entirely.
Identify Your Stage
Where Are You on the Norwood Scale?
The Norwood Scale classifies male hair loss in seven stages. Identifying your stage is the first step. The earlier you act, the more you have to protect.

How it works
The 3 Step Protocol System
Each protocol layer builds on the last - daily foundation, weekly intervention, and advanced optimisation.
01
Daily Foundation
Protocol 1 - Daily SerumThe non-negotiable daily step. Applied every morning to support a healthy scalp environment and maintain a DHT-conscious routine. Think of it as skincare for your scalp - consistent, lightweight, built for daily life.
02
Weekly Intervention
Protocol 2 - Micro Infusion KitOnce a week, used alongside Protocol 1. The micro infusion tool creates controlled micro-channels in the scalp's skin barrier to support deeper penetration of topical serums - reinforcing the daily routine at a deeper level.
03
Advanced Optimisation
Protocol 3 - Peptide Regeneration SerumCopper Tripeptide-1 based serum designed to support scalp repair and help prolong the hair growth cycle. Introduced once the daily foundation is established - the long-term optimisation layer for the most complete support possible.

The Barber Behind The Protocol
Built In A Barber's Chair. Not A Boardroom.
BT45 didn't start as a grooming brand. It started with Chris - a barber driven by curiosity and a need to understand not just how hair works, but why. Over 25 years ago, long before barbering became mainstream, every technique was learned through observation, experimentation, and refinement. After years specialising in Trichology and advanced education across barbering, hairdressing, and scalp health - working with global brands including L'Oréal and Alfaparf - The Protocol was built from a simple frustration: the men sitting in the chair were buying products that weren't working, because what they needed wasn't a better product. They needed a better routine.
“We don’t guess what people want. We hear it every day from the chair in front of us.”
This is not something you try.
This is something you commit to.
