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.
"Most brands sell a product.
We sell a structure

We sell a process."
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 Products
What's Inside The System
Three products. Three distinct roles. Designed to work as a system - not as standalone solutions.
Protocol 01 — Daily Foundation
Daily Serum
The foundation of The Protocol. A barber-developed daily scalp serum formulated to support a healthy scalp environment as part of a consistent routine.
- Supports scalp health and a healthy follicle environment
- DHT-conscious formulation
- Lightweight, non-greasy texture - designed for daily life
- Requires consistency - results build with routine
£39.99
Protocol 02 — Weekly Intervention
Micro infusion Kit
This is not about aggressive stimulation. The Protocol 2 Microinfusion Kit is designed for controlled intervention, creating micro-channels in the scalp's skin barrier to support deeper penetration of Protocol 1, reinforcing the routine at a deeper level. Used once weekly alongside Protocol 1.
- Creates controlled micro-channels to support topical absorption
- Reinforces routine structure - weekly activation
- Elevates the system beyond single-product topical use
- Available in 6 Month and 12 Month kits
From £119.99
Protocol 03 — Advanced Optimisation
Peptide Regeneration Serum
A Copper Tripeptide-1 based serum designed to support scalp repair and help prolong the hair growth cycle. Introduced once the daily foundation is established through Protocol 1 and 2, this is the advanced optimisation layer — designed for long-term support of the scalp environment.
- Copper Tripeptide-1 formulation to support scalp repair
- Designed to support prolonging the hair growth cycle
- Introduced after consistency with Protocol 1 is established
- The long-term optimisation layer of the system

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.
Common Questions
Frequently Asked Questions
Consistency is key. Most customers should allow a minimum of 8–12 weeks of regular use before assessing progress.
Hair grows in cycles, and improvements in scalp condition often happen before visible changes in hair appearance. For best results, we recommend following the full BT45 Protocol as directed and staying consistent with your routine.
Each Protocol has a specific role, but they work best as a complete system.
Protocol 1 – Daily Foundation Serum
Supports the scalp environment and forms the foundation of your daily routine.
Protocol 2 – Micro-Infusion System
Helps improve the delivery of active ingredients through targeted scalp application.
Protocol 3 – Peptide Regeneration Serum
Contains advanced peptides and supporting ingredients designed to complement the overall system.
You can purchase individual products, but the complete Protocol provides the most comprehensive approach.
Most products focus on a single solution.
BT45 The Protocol uses a three-stage system that combines:
• Daily scalp support
• Targeted micro-infusion technology
• Advanced peptide-based scalp care
The system was developed to help men build a consistent routine rather than rely on a single product.
Protocol 1 focuses on daily scalp maintenance and support.
Protocol 2 helps improve ingredient delivery through micro-infusion technology.
Protocol 3 contains advanced peptides, hydration support, botanical extracts, and scalp-conditioning ingredients designed to complement the overall system.
Together, the three Protocols create a structured approach to scalp care, helping men take action early and stay consistent over time.
Orders are typically dispatched within 1–3 working days.
Once your order has been shipped, you will receive tracking information by email. During product launches or promotions, dispatch times may be slightly longer and will be clearly communicated on the website.
Yes. Many customers choose to use The Protocol alongside their existing haircare and hair loss routines.
The Protocol is designed to complement a wider scalp care routine and can generally be used alongside other treatments.
As with any new product, if you are currently under medical supervision, taking prescription medication, have an existing scalp condition, or have any concerns about suitability, we always recommend consulting your doctor or healthcare professional before use.
If in doubt, seek professional advice before introducing any new hair or scalp treatment into your routine.
The Protocol is designed for men who want to take a proactive approach to their hair and scalp health.
Whether you’re noticing early signs of thinning, changes around the hairline, reduced density through the crown, or simply want to support what you already have, The Protocol is designed to fit into a long-term maintenance routine.
As with any haircare product, individual results will vary.
Hair and scalp care is an ongoing process, not a one-time fix.
Just like going to the gym or maintaining your skin, consistency produces the best long-term results. Many customers choose to continue using The Protocol as part of their regular grooming routine to support their scalp and maintain their progress over time.
