After washing and blow-drying your hair, it turns dry, frizzy and unruly like straw. It snaps easily when combed, and split ends keep appearing no matter how often you trim them. Shortly after dyeing and perming, your hair color fades and turns brassy, while strands become fragile and brittle. Even with piles of hair care products, you only get temporary relief with no long-term improvement. In fact, the root cause of all these issues is the continuous loss of hair keratin. Hydrolyzed keratin targets and resolves these problems precisely.
Healthkintai® offers hydrolyzed keratin powder with specifications ranging from 80% to 99% to meet all formulation requirements for your hair care products. Please feel free to contact us at health@kintaibio.com if you are interested.
What Is Hydrolyzed Keratin Made of?
Hydrolyzed Keratin is a compound active ingredient produced by hydrolyzing hard animal keratin sourced from wool, hair, feathers and other materials. It is mainly composed of high-content free amino acids, small-molecule polypeptides and trace minerals, and is rich in characteristic amino acids such as cystine, serine and glycine. Retaining unique disulfide bond structural fragments of keratin, it features small molecular weight, excellent water solubility and strong permeability.
It replenishes lost protein nutrients for skin and hair, repairs barriers, strengthens tissue texture and locks in moisture, serving as a widely used repairing and moisturizing ingredient in skincare and hair care products.
Does Hydrolyzed Keratin Straighten Hair?
Hydrolyzed keratin can penetrate and repair hair strands, mend cuticle damage, and form a moisturizing protective film. It effectively calms frizz, softens coarse hair, tames dry and unruly locks for a smoother, sleeker finish, and reduces the mess of mild natural waves to deliver a visually straighter appearance. However, it cannot alter inherent hair follicle shapes or break and rearrange hair disulfide bonds.
So it fails to permanently straighten tight natural curls and ringlets. It only provides gentle physical repair and temporary smoothing effects, which gradually fade after shampooing.
Hydrolyzed Keratin Benefits for Hair
Deep Repair of Hair Structure
After hydrolysis, hydrolyzed keratin features a reduced molecular weight, enabling it to penetrate raised and damaged hair cuticles and reach the hair cortex. Chemical perming, dyeing and high-temperature heat damage the native hair keratin, resulting in broken disulfide bonds, protein loss and microstructural cavities. The small-molecule polypeptides and amino acids in hydrolyzed keratin can precisely deposit inside these cavities. Containing cysteine sulfhydryl groups, it reconstructs disulfide bonds at broken sites, internally reinforcing hair structure, restoring hair density and mechanical strength, and reducing split ends and hair breakage.
Strengthen Hair Toughness and Elasticity, Reduce Hair Breakage
The tensile strength and elasticity of hair are determined by the helical structure of keratin fibers in the cortex and the crosslinking degree of disulfide bonds. When damaged, hair fibers become loose with reduced crosslinking, making hair brittle and prone to breakage. Hydrolyzed keratin replenishes lost structural proteins and amino acids (glycine, proline and cysteine), strengthens the keratin fiber network, and increases the crosslinking density of disulfide bonds. It enhances the hair's resistance to stretching and bending, lowers the hair breakage rate, and improves overall elasticity and toughness.
Cuticle Sealing & Smoothness and Shine Enhancement
Healthy hair cuticles fit closely together, while damaged cuticles lift and turn outward, causing frizzy, dull and easily tangled hair. Hydrolyzed keratin forms an even, breathable bionic protective film on the hair surface. It adheres to the edges of cuticles through intermolecular forces to help seal cuticles tightly and smooth raised scales. This reduces the friction coefficient between hair strands, greatly improving smoothness, luster and combability, as well as alleviating static electricity and hair tangling.
Resist External Damage
Anti-UV Damage: Hydrolyzed keratin forms a UV filtering film on the hair surface. Its polypeptide chains and amino acids absorb UV-B rays and reduce the degradation of cortical keratin caused by ultraviolet radiation. Meanwhile, small peptides produced by photodegradation can further penetrate and strengthen the hair structure, delaying photoaging.
Anti-Heat Damage: High temperatures break disulfide bonds and deplete hair moisture. The film-forming property of hydrolyzed keratin provides thermal insulation, lessening direct damage from heat styling tools, while replenishing proteins and moisture lost due to thermal stress.
Anti-Chemical Damage: Cysteine residues neutralize oxidizing agents from perming and hair dyeing, reducing the erosion of chemical reagents on hair cuticles and the hair cortex, and slowing down color fading and structural deterioration.
Hair Products with Hydrolyzed Keratin
Hydrolyzed keratin is a widely used natural repairing active ingredient in the hair care field. Hair care products containing this ingredient include shampoo, conditioner, hair mask, hair serum and more. With hydrolyzed keratin as the core ingredient, they are often compounded with nourishing components such as plant essential oils, panthenol and amino acids. Suitable for daily hair repair, perm and dye damage first aid and intensive care, these products are mild and low-irritating. With long-term use, hair can restore a healthy state of being soft, strong, smooth, shiny and full-bodied, making them a mainstream choice for the care of damaged hair.
Shampoo with hydrolyzed keratin Hydrolyzed keratin conditioner
Rosemary Hydrolyzed Keratin Shampoo
Rosemary extract gently conditions the scalp, boosts scalp blood circulation, relieves inflammation and balances sebum secretion. It alleviates scalp itching and dandruff, repairs the scalp barrier, strengthens hair roots and reduces excessive hair loss, creating a healthy environment for hair growth.
Hydrolyzed keratin is inherently compatible with natural hair components. Its small-molecule structure penetrates deep into the hair cuticles, fills internal hair cavities caused by perming, dyeing and heat damage, and seals the hair scales, effectively improving dryness, frizz, split ends and brittle hair.
The combination of the two ingredients delivers synergistic benefits. It nourishes the scalp and reinforces hair roots from the source while deeply repairing and moisturizing hair strands. It locks in long-lasting hydration, leaves hair soft, supple and glossy, and comprehensively enhances overall hair health and resilience.
How to Use Hydrolyzed Keratin on Hair?
Leave-in daily care
After shampooing and towel-drying damp hair, apply a small amount of hydrolyzed keratin serum or spray evenly from mid-length to ends. No rinsing needed. It seals cuticles, replenishes protein, and instantly smooths frizz and dry split ends.
In-shower deep treatment
Mix hydrolyzed keratin liquid with your conditioner or hair mask, leave on hair for 5–10 minutes, then rinse thoroughly. It penetrates damaged hair strands to fill protein gaps caused by heat styling, dyeing and perming, strengthening brittle hair.
Pre-heat protection
Spray hydrolyzed keratin on dry or damp hair before using hair dryers, straighteners or curlers. It forms a protective film on the hair surface, reducing high-temperature damage and locking in moisture.
Overnight intensive repair
For severely damaged hair, apply a thin layer of concentrated hydrolyzed keratin on ends before bedtime. Wash hair the next morning to achieve long-term hydration and restoration.
