Peak Girl Kératine hair protection capsule

To fully restore hair’s health and shine after the daily damage it is exposed to (like cold, dry, polluted air; hair styling equipment, hair dying), you’ll have to get down to the root of the problem.

Over 90% of hair is made of keratin, so it contributes largely to your hair’s strength and density.

The Peak Girl Kératine hair protection capsule contains all the essential amino acids and vitamins needed to build keratin and support growing a beautiful, healthy hair and nails. Keratin is also found in your skin, making it an essential component of your daily beauty routine.

What is Keratin Exactly?

More than 90% of the hair is made up of a protein called keratin. Keratin is a water-insoluble fibrillar protein that contains high levels of cysteine and sulfur. Keratin gives the hair structure strength and elasticity that can be weakened by external influences.

Examples of such external effects are:

- curling

- hair straightening

- hair dying

- hair spray and other chemicals

The human body is not able to digest keratin, therefore this supplement does not contain keratin itself, but contains the building blocks of it, like sulfur and cysteine.
