Keratin is a protein particularly used in hairdressing thanks to its many benefits. We are going to explain to you what keratin really is, what are its advantages and why its use is so frequent in the world of hairdressing.
WHAT IS KERATIN?
The raw material of the hair is composed of 85% Keratin. This natural protein is made up of amino acids that help build skin appendages: hair, hair, and nails. Keratin is formed thanks to the storage of dead cells which constantly rise towards the hair follicle. It does not regenerate during the life of the hair. Its role is to protect the hair from external aggressions, however, the more the hair is subjected to aggression, the less it naturally contains keratin.
The hair is largely composed of keratin, and each of the layers that make up the structure of the hair has a very specific function:
The cuticle , which constitutes the first layer, protects the hair by sealing all the scales of the hair between them. , giving it a smooth appearance. The cuticle stores water inside the hair to hydrate it naturally
The cortex , the second layer of the hair, is made up of fibers that define the elasticity and strength of the hair
The medulla , the third layer of the hair, serves from spine to hair
Keratin acts to strengthen and glue the scales of the hair, it comes to smooth the first layer of the hair, the cuticle. It protects, smoothes and gradually transforms the structure of the hair. It serves as a protective film and restores strength and shine to the hair.
KERATIN AND BRAZILIAN STRAIGHTENING
Keratin is a star active ingredient in Brazilian straightening , it allows you to modify the structure of the hair in depth. Brazilian straightening is used to relax the hair fiber of curly, frizzy or unruly hair towards a more supple and disciplined material. Keratin provides deep care for damaged hair, subjected to many coloring and/or bleaching techniques. Indeed, its formulation is richer in keratin than shampoos and conditioners containing this protein. The hair is repaired from the inside thanks to the preparatory action of the Step 1 shampoo.
Brazilian smoothing consists of 3 steps:
Step 1: Purifying shampoo – It cleanses the hair in depth, removing cosmetic residues and thus preparing the hair to receive the keratin treatment.
Step 2: Keratin treatment – It has a restorative action and helps relax the curl. It also brings softness and shine to the hair and facilitates styling.
Step 3: Seal the scales – Finally, some Brazilian straightenings consist of a last step in the form of a mask or spray which will seal the scales of the hair in order to trap the keratin and improve the final result.
Pro recommendation : Hairdressing pros recommend using a keratin maintenance range to maintain the effect over time. It is also best to avoid sulfate-based shampoos.
KERATIN FOR EXTREME PROTECTION
With keratin, the hair is protected. Thanks to its direct action on the cuticle, it fills and strengthens the scales of the hair. Keratin is a great ally to use with the Steampod 3.0 or other steam straighteners since products that contain keratin tame frizz and relax curly or unruly hair. It is also possible to integrate keratin-based hair care products into your usual hair routine. These products will act on the surface to strengthen the hair fiber, bring shine and vigor to the hair.
For example, the Brazilian Secrets Hair or Urban Keratin brands offer professional maintenance products (shampoo, mask, oil, cream, serum) based on keratin in order to continue the effects of smoothing at home. The K-19 restructuring treatment from NIKA ‘s K-Perfection range is very effective. Its powerful pure Keratin complex deeply rebuilds the hair fiber, reduces breakage and improves shine.
Keratin is a protein naturally present in the hair structure. Over time and following many techniques, it disintegrates and is no longer renewed. Using Keratin treatments can deeply treat the hair, giving it shine and softness. It is a powerful active ingredient used in Brazilian smoothing to deeply relax the hair fiber and limit breakage. If you have damaged or unruly hair, opt for deep keratin treatments to bring your hair back to life.
