Recombinant Humanized Keratin: Hair care is advancing from “surface modification” to “structural repair”

In today’s era of increasingly frequent hair coloring and perming, hair care products face a pressing challenge:

Hair is no longer simply “dry,”

But rather hair “The structure has been destroyed” 。

Oxidizing agents, reducing agents, and high‑temperature styling continuously degrade the keratin structure within the hair. If a product lacks genuine “structural repair,” no amount of smoothing agents will deliver lasting results—only superficial effects.

About 90% of hair is composed of keratin, and its structure is like… Reinforced concrete building ：

Cuticle = exterior wall , protects the internal structure and reflects luster;

Cortical layer = load-bearing wall , keratin fiber bundles are tightly interconnected by disulfide bonds and hydrogen bonds;

Keratin fibers = reinforcing steel, disulfide bonds = critical welds 。

Healthy hair has tightly packed keratin fibers, strong bonds at the cuticle level, and a smooth outer surface. Meanwhile, perming, coloring, bleaching, and sun exposure are all steadily undermining this structure.

Many people assume that hair damage simply means the cuticle scales are lifted, but in fact, that’s only the beginning of the damage. 

The true damage chain is: Damaged cuticle → exposure, breakage, and loss of internal keratin → hair becomes hollow and brittle. , ultimately resulting in split and broken hair.

Therefore, the root cause of hair damage is the loss of keratin. Replenishing oil and moisture can only improve the feel; it cannot repair structural damage. 。

Most “keratin” hair‑care products on the market actually contain Hydrolyzed keratin — Animal-derived small-molecule fragments obtained through strong alkaline or high-temperature hydrolysis of wool and feathers cannot achieve genuine repair, as they suffer from two fundamental problems: 
 

This is also the fundamental reason why it feels smooth when washed and returns to its original shape after blow-drying.

Recombinant Keratin is not “extracted” from animals; rather, it is produced through genetic engineering by isolating the core functional segments of the human keratin gene and obtaining a novel biomaterial with high activity, high stability, and high purity via microbial fermentation, expression, and purification. This represents a milestone breakthrough in global keratin preparation technology.

▶ Fill the hair core

It precisely penetrates the cuticle layer, filling in the gaps caused by heat styling, sun exposure, or chemical treatments, and rebuilds the hair’s natural protective barrier from within, restoring fullness to each strand.

▶ Reformation of disulfide bonds

Replenishes cysteine lost from the hair, re‑forms disulfide bonds with damaged keratin molecules, repairs broken fiber structures, and restores strength and elasticity to the hair.

▶ Repair the hair cuticle

It adheres to the hair’s surface, filling in damaged, lifted cuticles and realigning them for a tighter, more compact structure, effectively reducing frizz and restoring smoothness and shine to the hair.

▶ Moisture-locking protection

It forms a uniform, dense protective film on the hair’s surface, locking in moisture and nutrients to maintain hydration and deliver long-lasting improvements to hair quality.

 

Truly effective hair care doesn’t just mask problems—it solves them.

From “surface modification” to “structural repair,” Recombinant Keratin is redefining the paradigm of hair health through biotechnology.

In the future, we will continue to deepen our expertise in the field of Recombinant Keratin and expand Hair color fixation and hair loss prevention Enabling more application scenarios and delivering more precise, efficient hair‑care solutions for the personal care industry.
