WHAT'S IN THE PROTOCOL
THREE PRODUCTS. ONE SIMPLE ROUTINE.
Use all three for the complete Protocol, or start with the level that's right for you.
Protocol 1 - Daily Scalp Serum
£24.99The 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.
Protocol 2 - Micro Infusion Kit
From £49.99Once a week, as part of your routine. 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.
Protocol 3 - Peptide Regeneration Serum

HOW IT WORKS
WHAT DO I ACTUALLY HAVE TO DO?
Morning
Protocol 1: Daily Scalp Serum
Use every morning, except on Protocol 2 treatment days. Apply directly to the scalp. Allow it to absorb, then dry and style your hair as normal. Think of this as skincare for your scalp.
ONCE A WEEK
Protocol 2: Micro-Infusion
Use once a week, in the evening. Protocol 2 uses tiny needles to create small channels in the scalp, helping the serum absorb more effectively. Use one full 5 mL vial per treatment. Once opened, use it all that day and don't store any leftover. Skip Protocol 1 and 3 on treatment day and wait 48 hours before restarting them. Choose the 6+6 Kit or the 12+12 Kit.
NIGHT
Protocol 3: Copper Peptide Serum
Use every night, except on Protocol 2 treatment days. Apply to the scalp and leave on overnight.

When will I see results?
Built for consistency, not an overnight fix.
Hair grows slowly and every person's starting point is different. That's why The Protocol is about building a routine and sticking with it, rather than looking for an overnight change. Think about going to the gym; it's showing up consistently that counts.
Take photos when you start, then compare your progress over the months using the same angle and lighting each time.
Why BT45?
The Protocol started with the conversations Chris was having with men in his chair every day about hair loss. After 25+ years in the industry and further study in Trichology and scalp health, he wanted to create something straightforward that men could actually fit into everyday life. No complicated 10-step routine. Just a system built around consistency.
“We don’t guess what people want. We hear it every day from the chair in front of us.”
Want to Know the Science behind The Protocol?
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.
01 What is DHT?
DHT is a hormone involved in male pattern hair loss. In people who are genetically sensitive to it, it can contribute to hair follicles gradually producing finer, shorter hairs.
02 What are Peptides?
Peptides are small chains of amino acids. They are used in many skin and haircare formulas. Protocol 3 contains Copper Tripeptide-1 as part of its scalp-care formula.
03 What's Micro-infusion?
Protocol 2 uses tiny needles to create micro-channels in the surface of the scalp and is used as part of your weekly routine. They are small needles that help aid absorption of serum. They shouldn’t be sore.
Frequently Asked Questions
It depends on where you are with your hair. Protocol 1 is the starting point for daily scalp care. Protocol 1 + 2 adds a weekly micro-infusion treatment if you're starting to notice thinning or changes to your hairline. The Full Protocol (1 + 2 + 3) is the complete routine, adding peptide-based scalp and hair support. Not sure? Take our quick quiz to find your Protocol.
We've designed The Protocol so you can choose a routine that suits where you are now. If you want the complete routine, use Protocols 1, 2 and 3 together.
That's a good time to start building a consistent routine. We recommend Protocol 1 daily scalp care with Protocol 2, a weekly micro infusion kit, choosing either the 6+6 Kit or the 12+12 Kit.
Yes. Protocol 1 can be used on its own as a simple daily scalp-care routine. It's also the starting point if you don’t need the full system yet.
Protocol 1: Every morning as part of your daily routine
Protocol 2: Once a week
Protocol 3: Every night
Yes, for Protocol 1 apply directly to your scalp, give it time to absorb (around 2-5 minutes), then dry and style your hair as normal. Protocol 2 and 3 are evening based routines, so you shouldn’t have to worry about hair wax before bed!
Yes, you can. Ideally, if you are serious about your hair loss journey, you should be using a specialist hair loss or caffeine based shampoo as this will only further support your results.
Yes. The Protocol looks after your scalp and hair as part of your routine; your BT45 styling products can still be used to create your finished style. Apply The Protocol as directed, allow it to absorb, then style as normal.
Peptides are small chains of amino acids. In simple terms, they're ingredients commonly used in skin and haircare products to support the condition of the skin and hair. Protocol 3 contains Copper Tripeptide-1 as part of its formula to aid regeneration.
DHT is a hormone naturally produced by the body. Some men are genetically more sensitive to it, and over time this can contribute to hair follicles becoming smaller and producing finer, shorter hairs.
Protocol 2 uses tiny needles to create small channels in the surface of the scalp, helping serum get where it needs to go more effectively. It's used just once a week as part of The Protocol routine.
No. The Protocol does not contain minoxidil or finasteride. If you're using either, always check with your doctor before combining products or changing your routine, as each person is unique.
Think months, not weeks. Hair takes time, so don’t expect overnight changes. Everyone’s hair is different, but the key is giving your routine time to work and staying consistent.
Same angle. Same lighting. Same areas. Take clear photos before you start, focusing on your hairline, crown or wherever you’ve noticed changes. Keep taking photos over the months using the same lighting and angles, it’s much easier to see changes this way than checking the mirror every day.
Consistency is key. The whole Protocol system is built around this ethos. It isn’t about using something for a few weeks and stopping, it’s about creating a simple hair and scalp routine you can stick to long term.
The world won’t end! Just get back into your routine as soon as you can, there’s no need to overthink it. The easiest way to stay consistent is to make The Protocol part of something you already do. Keep Protocol 1 beside your toothbrush as a reminder to use it every morning, or set a daily and weekly reminder on your phone if you need the extra nudge.
Yes, The Protocol can form part of your ongoing hair and scalp routine after a hair transplant.
Your transplant clinic knows your scalp and recovery best, so always follow their aftercare advice and make sure they're happy for you to introduce new products or treatments first.
We recommend waiting at least 6 weeks and checking with your transplant surgeon or clinic before starting. Everyone heals differently, so your clinic's advice should always come first, particularly before introducing Protocol 2 and its micro-infusion step.
The Protocol may be used as part of a routine by people who are already using minoxidil or finasteride, but everyone's treatment and circumstances are different. Don't stop, change or combine prescribed treatments without checking with your doctor first.
Potentially, but it depends on what you're already using. If you're using another scalp treatment, medicated product or prescription treatment, check with your doctor, pharmacist or hair-loss specialist before adding The Protocol. This helps avoid unnecessary irritation or combining products that may not be suitable for your scalp.
The difference is the amount of Protocol 2 you receive. You can start with the 6-month option, or choose the 12-month option for better long-term value. We encourage a longer-term approach because The Protocol is all about consistency and measuring progress over months, not weeks. Important: The 6 and 12-month options apply to Protocol 2 only. Protocols 1 and 3 are each supplied as one unit.
Based on recommended usage of 1 mL per day (about one full dropper), each 30 mL bottle of Protocol 1 and Protocol 3 lasts approximately 30 days / 4 weeks. This can vary slightly depending on individual use.
Yes. Protocols 1, 2 and 3 can all be purchased separately, so you can choose the products that best suit where you are with your hair and your routine. You can also choose the Full Protocol System if you want the complete routine.
