II. Core Efficacy and Mechanism of Action
SH-Oligopeptide-78 is a bioinspired active peptide capable of penetrating deep into hair follicles and fundamentally reshaping hair structure, with its core advantage lying in the unique "disulfide bond binding mechanism".
Bionic reconstruction and hair core reinforcement: This component is rich in sulfur-containing amino acids (particularly cysteine), enabling precise replication of the structural proteins found in hair.It does not rely on hydrophobic binding domains but directly interacts with sulfhydryl groups in hair to form stable disulfide bonds, rejoining the damaged keratin peptide segments and fundamentally restoring the integrity of hair keratin.
Durable repair and long-lasting resistance to damage: Thanks to its exceptional bonding capacity, this ingredient ensures persistent fixation in hair even after multiple rinses.It effectively repairs keratin fiber damage caused by frequent hair washing, coloring, perming, and high-temperature styling, significantly enhancing the hair's resistance, elasticity, and toughness.
Hair scale closure and texture restoration: Under wet hair conditions, this ingredient penetrates thoroughly into the deepest layers of the hair shaft and repairs the squamous surface layer, preventing hair surface degradation.Long-term use imparts soft, smooth, dark-black, and glossy hair texture without damage, effectively improving dryness and frizz.
III. Recommended Addition Ratios and Application Scenarios
The SH-oligopeptide-78 formulation exhibits excellent compatibility and can be formulated into various dosage forms including shampoos, conditioners, hair masks, sprays, serums, perming agents, and hair dyes.
Daily hair care products (shampoo/conditioner): The recommended addition concentration is 0.05%–0.1% (based on powder purity ≥95%).Ideal for maintaining and conditioning daily-damaged hair, enhancing its softness and smoothness.
Deep repair care (hair mask/wash-free essence): Recommended concentration is 0.1%–0.5%.Designed for hair frequently exposed to heat styling and thermal damage, it provides comprehensive repair to enhance hair strength and resilience.
Professional salon chemical treatment (for use with hair dye or perming agents): Recommended concentration range is 0.5%–2%.Added in real time during bleaching or perming processes as a hair strengthening agent, it minimizes molecular-level damage to hair strands caused by chemical agents.
IV. Safety Compliance and Formulation Advantages
Mild, safe, and free from side effects: This ingredient is derived directly from keratin itself and synthesized through biotechnological fermentation. It exhibits inherent safety properties, causes no irritation to the scalp or hair strands, and is suitable for all types of sensitive scalps and severely damaged hair conditions.
Broad formulation compatibility: It can be easily incorporated into aqueous or conventional hair care formulations and exhibits excellent compatibility with common hair care ingredients such as cationic surfactants and plant oils.
Professional Hair Care Standard: As a specialized active peptide ingredient for cosmetics, it is specifically designed to enhance hair appearance, texture, and resilience, making it the ideal core component for premium hair restoration products.
Do I need to combine these two ingredients into a promotional copy for a blended product?For example, combined formulations such as "Dipeptide Bond Repair Essence".
