Available to order now - ships end of June
Protocol 3 is not where you start. It's where you go once the foundation is built.
The Peptide Regeneration Serum is a Copper Tripeptide-1 based serum formulated to support scalp repair and help prolong the hair growth cycle — the advanced optimisation layer of The Protocol system, introduced once daily consistency through Protocol 1 has been established. It's not a shortcut and it's not a standalone solution. It is, however, the most complete expression of what long-term scalp support looks like.
Copper Tripeptide-1 is recognised for its role in supporting tissue repair and the skin's natural regeneration process. Applied to the scalp as part of a structured routine, Protocol 3 is designed to support the scalp environment at the level where long-term change is possible.
Precision over hype. Education over exaggeration. This is the BT45 approach — and Protocol 3 is where it reaches its furthest point.
• Copper Tripeptide-1 formulated to support scalp repair

• Supports long-term scalp optimisation — not short-term fixes
• Introduced after Protocol 1 consistency is firmly established
• The advanced layer of the full three-step Protocol system
• Results develop over time — consistency and commitment required

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, promotions, or pre-order periods, 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.
I think this is worth adding as it is one of the most common questions people ask when considering any hair loss routine and should help reduce customer enquiries.
