How Does Acetyl Tripeptide-30 Citrulline Enhance Hair Keratin?
01
Product Description
1. MOA
Acetyl Tripeptide-30 Citrulline is a biomimetic peptide specifically designed to target the root cause of hair weakening and loss by acting directly within the hair shaft and follicle.
Stabilization of Hair Keratin: The peptide's sequence is designed to mimic the natural amino acid sequences involved in the formation of the hair shaft's internal protein structure. It integrates into the hair fiber, promoting the formation of additional cross-links between keratin proteins. This action reinforces the internal cohesion of the hair shaft, making it mechanically stronger and more resistant to breakage.
Protection against Proteolytic Damage: It helps protect hair keratin from enzymatic degradation (e.g., from microbial proteases), which can weaken the hair fiber and lead to premature hair breakage and thinning.
Improved Hair Anchor in the Follicle: By strengthening the hair shaft from within, the hair is more securely "anchored" in the follicle. This reduces the rate of hair loss due to breakage and can help extend the anagen (growth) phase of the hair cycle by maintaining a healthier hair structure.
2. In Vitro Efficacy Data
Hair Strength Resistance: In vitro tensile strength tests on human hair fibers treated with Acetyl Tripeptide-30 Citrulline showed a significant increase in resistance to breakage, with improvements of over 30% compared to untreated hair.
Keratin Protection: Models demonstrated the peptide's efficacy in protecting hair keratin from degradation by specific proteolytic enzymes.
Penetration Studies: The acetyl group enhances the penetration of the peptide into the hair shaft, confirming its ability to reach the site of action.
3. Clinical Results
Clinical studies on human volunteers confirm the in vitro findings, demonstrating visible and measurable improvements in hair quality and reduction in hair loss.
Reduction in Hair Breakage/Loss: A 3 to 6-month clinical study with a topical solution containing Acetyl Tripeptide-30 Citrulline (e.g., at 5 ppm) showed a statistically significant reduction in hair loss due to breakage by up to 60% when measured by the hair pull test and daily hair count.
Increase in Hair Density: Participants exhibited a visible increase in hair density and overall hair volume, as confirmed by macrophotography and trichoscopic analysis.
Improved Hair Strength & Quality: Self-assessment questionnaires reported a significant improvement in hair strength, reduced brittleness, and an overall healthier appearance.
Safety Profile
Acetyl Tripeptide-30 Citrulline is well-tolerated and non-irritating when applied topically to the scalp at recommended use levels. It is suitable for sensitive scalp.
Compatibility
Synergistic Combinations:
*Stimulating Agents (e.g., Caffeine, Niacinamide): To simultaneously stimulate microcirculation and hair follicle activity.
*Other Hair Growth Peptides (e.g., Acetyl Tetrapeptide-3): For a multi-targeted approach to combat hair loss.
*Panthenol (Provitamin B5): To provide hydration and shine to the hair shaft, complementing the strengthening effect.
*Saw Palmetto Extract: To help target hormonal factors of hair loss.
Formulation Stability: It is stable in aqueous systems within a standard cosmetic pH range (4.0-7.0) and can be incorporated into various serum, lotion, and spray formulations.
