Keratin is a complex protein that is found in the skin, teeth, nails, and hair, as well as in the horns and hoofs of animals. But most of it is in the hair because the hair consists of keratin by over 85%. It might be a reason why professional hair care products with keratin are so effective, especially hair masks.
If your body is unable to synthesize the necessary amount of keratin by itself (and not only for the healthy hair), then it is important to boost it. First of all, you should fill in the shortage of keratin from the inside, meaning, that you need to eat food enriched with proteins on daily basis. In your diet, add meat, fish, liver, dairy and other products that contain animal protein. Vitamins of group B (and especially B6) are involved in the production of keratin which you can read more about simply by doing a bit of research online.
In addition to this, keratin is also produced when there is a sufficient supply of sulfur, nitrogen, silicon and other important elements in our body.
But, remember to nourish keratin from outside!

HOW BENEFICIAL IS KERATIN FOR HAIR?
Keratin is a natural protein that is found in the hair in a large percentage. If your hair is dry, brittle, fragile and especially damaged, then keratin is what you need. Keratin contains an amino acid responsible for the elasticity, smoothness, and health of the hair. It gives shape to the hair, determining whether our hair is curly or straight. In straight hair, there is much more keratin than in curly hair. At the same time, dark hair strands contain more keratin than blonde hair since blonde hair easily reflects the sunbeams, while dark hair needs more thorough protection.
The reason why keratin is so beneficial for your hair is that its molecule is able to penetrate and fill the hair, thereby improving its structure from inside. Not every substance for a hair remedy contains such useful feature. Basically, all the active substances work on the top of your hair and create only the illusion of hair recovery.
Professional cosmetic brands produce liquid keratin as it acts directly on the weakened sections of your hair. As a result, structural damage is recovered. It is also able to rejuvenate the intercellular space of the hair structure and create molecular structures to protect hair from the damage.
Keratin amino acids usually consist of the 19 most important amino acids that are responsible for restoring the normal level of moisture in the hair, resulting in hair strengthening, shine, and elasticity.

Today, hair straightening procedures based on keratin are also quite popular, and we will discuss them in the future blog posts.
WHAT DOES KERATIN BREAK DOWN?
The lack of keratin makes the structure of the cuticle more porous and fragile. As a result, the protective layer of the hair ceases to retain moisture, and the hair becomes dry, brittle and lifeless. If the amount of keratin reduces in the stratum corneum, scales of the hair cuticle loosely connect each other and bristle up like a pine cone.
Much depends on our nutrition: poor-quality and harmful foods, strict diets, irrational nutrition lead to a deficiency of natural keratin in our hair.
Keratin degrades at high temperatures. Therefore, it is necessary to use the hair dryer carefully, especially hair straightener and curling iron. More importantly, always use thermal protection. Too high temperature damages the cuticle and leads to a loss of moisture in the hair, which, in its turn, leads to dryness and fragility of the hair.
Hair structure also breaks down when dying as the coloring pigments penetrate the cuticle, the protein bond is broken and the hair eventually becomes dry and brittle, including all other chemical procedures that destroy the moisture of your hair, and therefore, should be avoided or reduced at least. The constant use of foam, gel, spray, and wax for hair also contributes to the damage of your hair.
Summing up, we can say that, first of all, you need to take care of the abundance of natural keratin in order not to buy remedies based on keratin. Therefore, make sure to eat smart for better hair and body health.
