One of the main ingredients for healthy hair is keratin. But a lot is still discussed in relation to some myths and truths regarding this protein. Can the wires break? Will it harden or straighten your hair? Next, we’ll check out some important information about the protein, and what can be done – and avoided – to have a healthier hair.
What is keratin?
Is a protein made up of 15 amino acids, the most predominant in this case, known as cysteine, is responsible for protecting and giving resistance to some parts of our body, the main one is the hair. Cysteine represents 90% of the formation of follicles, being the main responsible for those who have life, strength and elasticity.
The places where most keratin is found in the body are hair and nails.
The role of this protein in hair
In the case of hair, keratin has the function of protecting and preserving the nutrients existing within the hair, that is, it prevents water loss in the capillary region, protects the hair and gives it a brighter visual appearance. The problem is that when aggressions occur in the hair region, such as the use of a hair dryer and flat iron, or proceedings, it can result in brittle hair.
How does hair keratin loss happen
Keratin loss is a process that occurs naturally, due to sunlight and other elements, but high temperatures such as a hair dryer and flat iron also influence the loss of proteins, due to the high temperature, another factor that can influence, are the proceedings performed on the hair.
Some examples are:
Flat iron, hair dryer, solar radiation, coloring, bleaching, progressive brush, and some others chemicals.
Replacing lost protein
The replacement of lost protein can be done with the application of synthetic products, applied to the hair to restructure the wires.
Nanokeratinization: Made with a brush, connected to a device with liquid keratin.
Cauterization: Performed with cleaning, hydration, and a load of keratin on the flat iron, finally, it is finished with silicone.
Hair reconstruction: Recommended for cases of extremely damaged hair, keratin and other proteins are deposited, as well as minerals, for hydration and protection.
Care to prevent protein loss
– Decrease the use of flat iron, hair dryer;
– If using, apply a thermal protector before;
– Space the retouching of your color further;
– Only bleach your hair with a professional.
Keratin can straighten hair
Here we have the case of the first “myth” in relation to keratin, people with wavy or curly hair do not need to worry about the use of keratin, it is just a reconstructive treatment that enriches the wires with protein.
Keratin can harden or cause hair breakage
Another myth that revolves around the use of keratin – as long as it is not overused – the use of keratin makes the hair wires stronger and more resistant, making the replacement of lost protein. In case of excessive use, the opposite can occur, the hairs will have a more rigid appearance, which can result in a more hardened and brittle appearance.
