Liquid Keratin Repairing Pure Keratin Serum (20 mL) - Natural Hair Keratin for Severely Damaged, Burned, and Split-Ended Hair

This pure liquid keratin serum is formulated to repair hair damaged by chemical treatments, high heat, and external factors. It quickly penetrates deep into the hair shaft to fill in damaged areas, strengthen split ends, and restore your hair to a vibrant, strong, and smooth appearance.

Highlights

With its pure liquid keratin, it strengthens and restores the hair shaft.

Helps to repair the damage quickly occured after chemical and heat treatment.__t7__

Restores broken hair ends, reduces breakage and loss of elasticity.__t8__

Deeply nourishes hair, leaving it soft and supple.

Does not contain formaldehyde, is not a smoothing product, only for restoration.__t10__

Helps protect hair from heat styling and chemical damage.

Suitable for pregnant women, nursing mothers and all hair types.__t12__

How to Use

Clean your hair thoroughly with a keratin shampoo.

Apply the serum evenly to dry or damp hair. a slight tackiness is normal upon initial application.

Wait 10–15 minutes and rinse.__t17__

Then, apply a keratin mask or treatment cream for extra softness.__t18__

For severely damaged hair, we recommend a total of 3 treatments, spaced 3 days apart.

Contrary to popular belief, keratin is not just an ordinary chemical substance. It is a fibrous bioprotein naturally found in hair, nails, and skin tissue that possesses high strength. It is the fundamental building block that provides the hair strand with its mechanical strength, elasticity, and integrity. Approximately 70 to 75 percent of human hair consists of keratin proteins. This percentage clearly demonstrates just how critical a role liquid keratin plays in hair health.

Molecular structure of keratin

Keratin is a complex protein chain composed of numerous amino acids linked together. Its structure includes amino acids such as cysteine—in particular—as well as methionine, glycine, alanine, and serine. Thanks to its cysteine content, disulfide bonds form between liquid keratin molecules. These bonds are the primary factor determining the hair strand’s mechanical strength, elasticity, and resistance to breakage. The amino acids form long keratin chains by bonding to one another. These chains are arranged in a fiber-like structure and form the hair’s internal skeleton.

Everyday hair treatments directly target the hair’s keratin structure. Hair dyes, powder bleaches, high heat, and chemical styling treatments weaken or break the disulfide bonds in the keratin chains. As a result, protein gaps form within the hair shaft’s internal structure. This condition manifests in the hair as symptoms such as rubbery, stretchy texture, dullness, stiffness, breakage during growth, split ends, static, and frizz.

What is liquid keratin?

Liquid Keratin is a liquid form of pure keratin protein that has been hydrolyzed and broken down into micro- and molecular-sized particles. Thanks to this process, the keratin can penetrate all the way to the cortex layer without remaining on the surface of the hair shaft. In other words, Liquid Keratin is not just a hair care product that coats the hair, but a biotechnological repair agent that works on the hair’s internal structure.

Mechanism of action of liquid keratin

Hydrolyzed liquid keratin molecules target protein gaps in damaged areas of the hair shaft. By filling these gaps, they complete the keratin chains, restore the hair shaft’s internal integrity, and restore lost elasticity. For this reason, the Liquid Keratin treatment provides structural improvement rather than just superficial softness.

Liquid keratin effect on burned and damaged hair

Liquid keratin for hair that's been exposed to lightening, dye, and intense heat thickens the hair shaft from within, repairs the structure damaged by breakage and growth, and reduces split ends. it smooths the hair's surface. the stiffness and loss of elasticity observed in burnt hair gradually improves with keratin supplementation.

Difference between keratin protein and liquid keratin

Keratin protein is a raw material found in the natural structure of hair.liquid keratin, on the other hand, is a bioavailable form of this protein that can be applied to the hair.in this way, keratin can directly reach the inside of the hair strand and initiate a faster, more permanent repair process.__t38__

Why is regular use important?

Keratin repair isn't a one-time fix. liquid keratin gradually enhances its effect with each application, building up protein in the hair strand. with consistent use, hair becomes more resilient, thicker, more flexible, and better protected against future damage.

Liquid keratin treatment at home: a quick guide

Hair is washed with a sulfate-free clarifying shampoo. liquid keratin is then evenly applied to damp hair and left on for 5-6 hours. after rinsing, a mask is applied, and the hair is blow-dried. this treatment helps replenish the protein lost by the hair.
