Keratin: what it is, what it is for and cruelty free alternatives in hair treatments

Hair Treatments

Keratin is a substance often found in hair treatments. Few, however, know that it is a product of animal origin. Let’s find out what it is for and the equally good cruelty free alternatives to take care of our beauty.

Keratin is among the most used and advertised ingredients in hair care products. But what is hidden behind this substance?

Keratin, what is it?

It is a fibrous protein consisting of long chains of amino acids in which mineral salts and vitamins are also interspersed. Keratin is of animal origin and is found in the feathers, mane, hooves and horns of different animals. We humans also produce and use keratin primarily in hair, hair and nails.

Known primarily as an addition to some shampoos, conditioners or hair treatments, in reality this substance is also often used by the pharmaceutical industry to cover the gastro-resistant capsules.

Keratin, what is it for?

In treatments and hair products, keratin is often inserted with the function of making them more smooth and silky. This happens because this protein is rich in cysteine, an amino acid composed of various sulfur atoms that allows you to create very tight chains ensuring health and solidity to the hair. Basically, the keratin chains adhere to the hair and they recompose the fibers that compose them, helping to volumize them and make them stronger and more fit from the inside.

This substance is also often used in treatments for frizzy hair as it has a marked smoothing and softening capacity.

But why is the use of keratin necessary? The problem is that often the health of our hair is severely tested by the use of aggressive products (for example dyes and bleaches) but also by pollution, chlorine pools, sun, etc. There may also be internal factors that make our hair more fragile, such as taking certain medications, the consequences of severe stress, hormonal problems and more.

In reality, even if the products loudly advertise the presence of keratin inside, they do not always contain large quantities and even in some cases they are keratinosimile proteins. If you do not want to risk, however, we present cruelty free alternatives to keratin, of sure natural and vegetal origin.
