💇 A professional scalp-treatment vial built around a multi-peptide and hydrolyzed keratin complex — designed to nourish follicular tissue and support visibly thicker, stronger hair over a structured recovery arc.

The SP55 protocol gives practices something most category alternatives don't: a defined treatment timeline — one vial every 10 days across a 50-day standard cycle, transitioning to a monthly maintenance phase. That rhythm creates repeatable appointment anchors, keeps clients returning on a predictable schedule, and pairs naturally with in-salon microneedling services where scope of practice allows. The leave-on formula applies to a clean, dry scalp and absorbs within minutes, making it compatible with a focused scalp session without requiring additional rinse time.

The unisex positioning broadens your eligible client base — men and women experiencing thinning or reduced density are both candidates for this protocol.

• Scalp and Follicle Nourishment: The concentrated peptide, amino acid, and micronutrient complex delivers nutritional support directly to the scalp surface, helping to maintain a healthy environment around the hair follicle.
• Improved Appearance of Hair Thickness and Strength: Hydrolyzed keratin and the multi-peptide complex help reinforce the hair fiber, contributing to a visibly thicker, stronger appearance over the course of the treatment program.
• Scalp Rebalancing: The combination of botanical extracts and nutrient actives helps condition the scalp, supporting a balanced environment that is more receptive to hair recovery protocols.
• Structured Long-Term Protocol: Packaged as a 5-vial set designed for a 50-day standard treatment cycle (one vial every 10 days), with a maintenance phase of one vial every 30 days, providing a defined professional treatment arc.

Multi-Peptide Complex (>150 amino acids): A concentrated blend of peptides and amino acids that serve as the structural building blocks for keratin, the primary protein of the hair shaft. Delivered directly to the scalp, this complex helps nourish follicular tissue and supports the conditions for stronger hair fiber production.

Hydrolyzed Keratin: Protein fragments derived from keratin, sized to reach the scalp surface and hair follicle opening. Helps reinforce the structural integrity of weakened hair fibers, contributing to a thicker, stronger feel along the hair shaft.

Biotin, Vitamins & Trace Minerals: A micronutrient complex including biotin (vitamin B7) alongside additional vitamins and trace minerals. Biotin is recognized as a cofactor in keratin biosynthesis; the broader micronutrient profile helps support normal follicular metabolism and is commonly included in follicle-nourishing scalp formulations.

Botanical Extracts: A blend of plant-derived extracts included to complement the peptide and nutrient complex. Botanical extracts in scalp leave-on treatments are typically incorporated for their antioxidant and scalp-conditioning properties, helping to maintain a balanced scalp environment.

1. Confirm the client has no open wounds, active scalp infections, or contraindications before beginning the session.
2. If using microneedling enhancement, apply the derma roller or derma pen (0.5 mm) to each affected scalp section, rolling approximately 10–15 times per section to increase scalp permeability prior to product application.
3. Ensure the client's scalp is clean and completely dry before applying the vial contents.
4. Open one vial and dispense the contents directly onto the scalp, distributing evenly across the target areas.
5. Massage the product thoroughly into the scalp to aid absorption and support local circulation.
6. Allow a minimum of 5 minutes for complete absorption before the client touches or covers the area.
7. Instruct the client to avoid washing their hair for the 8 hours following the session.
8. Instruct the client to avoid direct sunlight on the treated scalp area for the 8 hours following the session.
9. For the standard SP55 treatment program, schedule one vial session every 10 days (5 vials over 50 days).
10. Following completion of the standard protocol, transition to a maintenance schedule of one vial every 30 days.

Protocol timing and microneedling scope of practice

Schedule vial sessions strategically around the client's calendar — the 8-hour no-wash and sun-avoidance window means late-afternoon or evening appointments work well for clients who cannot avoid daytime sun. Before incorporating a derma roller or derma pen into the protocol, verify that microneedling is within your license category in your state; scope-of-practice rules vary and some jurisdictions restrict even shallow mechanical needling to medical or advanced esthetic licenses. Documenting client consent and a pre-treatment scalp assessment for each session also supports professional liability protection.
