Men's Hair Tonic

Traditional barbershop hair tonics from brands like Clubman Pinaud or Vitalis typically contain alcohol, witch hazel, fragrance, and botanical extracts for sensory experience and styling. Modern peptide-based hair serums like our Hair Tonic use amino acid complexes studied in clinical research. The NIH describes GHK-Cu copper peptides as compounds examined for tissue processes and collagen production, providing scientific backing for appearance benefits. Our formulation focuses on peptide technology rather than fragrance or styling effects.

Witch hazel, essential oils like rosemary or citrus, and botanical extracts like nettle leaf or horsetail root are common in traditional men's grooming products for fragrance and sensory effects. However, these ingredients weren't studied for their role in supporting hair follicle appearance or scalp health in the same way copper peptides were examined in research. We exclude botanical ingredients to maintain the peptide concentrations studied in clinical literature. The NIH research examined GHK-Cu as a specific amino acid sequence, and diluting with botanicals would reduce the peptide concentrations referenced in published studies.

PLU Laboratories sells cosmetic products, not FDA-approved drugs, so we cannot make claims about growing hair or treating hair loss. However, the NIH research describes copper peptides as compounds studied for tissue processes and collagen production pathways. Clinical research on Acetyl Tetrapeptide-3 examined hair follicle activity appearance. Our Hair Tonic uses these peptide concentrations for cosmetic use to support the appearance of hair density and scalp health. Traditional hair tonics with alcohol and botanicals were not studied for these mechanisms.

The NIH literature describes copper peptides as compounds studied in tissue processes that may involve circulation-related pathways. However, as a cosmetic product, our Hair Tonic is designed to support the appearance of scalp health rather than make medical claims about improving blood circulation. Traditional hair tonics used alcohol and menthol for a tingling sensation, which created the feeling of improved circulation without clinical backing. Our peptide-based approach focuses on amino acid signaling pathways studied in research on tissue remodeling and scalp health appearance.

Our Hair Tonic is formulated as a peptide-based hair serum for scalp health appearance and hair density support, not as a styling product. Traditional barbershop hair tonics often contained styling agents, alcohol, and oils that provided hold, texture, or shine for styling purposes. If you're looking for hair styling products with hold or texture, traditional grooming tonics or hair styling serums may be more appropriate. Our focus is exclusively on the peptide technology studied in clinical research for hair follicle appearance, applied to clean scalp once daily.

Many hair care products include vitamin E, argan oil, or other natural oils for moisturizing benefits. However, the clinical research on copper peptides examined GHK-Cu and Acetyl Tetrapeptide-3 as focused amino acid complexes, not mixed with oils or antioxidants in the same formulation. Adding vitamin E or oils would dilute the peptide concentrations studied in research. Our Hair Tonic maintains the peptide concentrations examined in NIH literature and clinical studies. If you want additional moisturizing ingredients for dry hair, apply those products separately after the peptides absorb.

After washing, gently towel-dry your hair until damp but not dripping. Apply 2-3 drops of Hair Tonic directly to your scalp, focusing on areas where you want to support hair density appearance. Massage gently with fingertips in a circular motion to distribute the peptide-based serum across the scalp. The dual-peptide system (GHK-Cu + Acetyl Tetrapeptide-3) absorbs quickly without greasy residue, unlike alcohol-based traditional hair tonics. Apply once daily to clean scalp for optimal results. The entire application takes under 30 seconds as part of your men's grooming routine.

Yes. Apply our Hair Tonic to clean, towel-dried scalp first, before any styling products or other hair care products. The peptide-based serum absorbs quickly, allowing you to layer hair oils, styling products, or other grooming products afterward. For comprehensive peptide support across hair and skin, combine with our Face Tonic containing GHK-Cu and Matrixyl 3000 peptides. This creates a complete men's grooming routine using science-backed peptide technology rather than traditional botanical-based products.

Traditional barbershop hair tonics were formulated for fragrance, styling, and sensory experience rather than hair follicle appearance. The NIH research on copper peptides describes specific amino acid sequences studied for tissue processes and collagen production pathways. Clinical research on Acetyl Tetrapeptide-3 examined hair follicle activity appearance. Our peptide-based Hair Tonic uses concentrations studied in published literature for supporting scalp health appearance and hair density, representing modern men's grooming backed by clinical research rather than legacy formulations focused on fragrance and alcohol content.

Our Hair Tonic comes in a 1 fl oz (30 mL) bottle. With the recommended application of 2-3 drops to clean scalp once daily, one bottle typically lasts 8-12 weeks depending on usage. The peptide-based formulation is highly concentrated compared to traditional hair tonics, so a little goes a long way. Unlike alcohol-based grooming products that evaporate quickly, the dual-peptide system (GHK-Cu + Acetyl Tetrapeptide-3) is designed for efficient absorption without product buildup or waste.
