What makes our hair look healthy and lustrous? What do its natural growth and lifecycle depend on? To find the answers to these questions we first need to know what our hair is made of and how it is formed. There are many different biological processes going on in human bodies. One of them is the so called keratinization. In course of this process the insoluble protein keratin (a.k.a horn matter) is being deposited in the epidermal cells. Keratinization is the main reason for natural hair growth. It occurs constantly making the cells transform into horny plates. Hence, our hair is basically composed of keratin and its growth and condition wholly depend upon this substance.
Keratin is formed in hair follicles. The new keratin is very gentle, especially at the hair root, making hair soft and silky. With the growth of keratin hair becomes firmer and stronger. Due to it our hair has the proper structure and integrity. There are no such problems as hair loss, split ends, tousled hair if there is 100% of keratin in hair. In this case hair has no weaknesses and is least susceptible to various disorders. Keratin prevents hair from dehydration what is significant for its healthy growth. If the process of keratinization goes on as it should without interruption, our hair will always have healthy shine and strength.
Keratin can not appear by itself out of nothing. For its formation and density it needs proteins which contain sulfur atoms. Therefore, it is of vital importance to include proper foods in your diet plan. Light meat (poultry and fish) and plant products composed of amino acids are very useful for keratinization and formation of healthy hair structure. Once proteins are ingested with food, they split into thin amino acids which are transferred with blood to all vital organs, including hair follicles.
Natural hair growth and its thickness depend on the amount of proteins that we consume. It is advised to eat sour fruits together with protein rich foods as it helps proteins be digested properly. In this case the stomach produces a sufficient amount of gastric juice containing pepsin, which helps to split molecules of food. If that doesn’t happen, keratin can’t be produced or it is produced in low amounts. Vitamin B6 is also very important as it accelerates protein metabolism. Such foods as nuts, a variety of embryonic germ, soybeans and liver are excellent suppliers of vitamin B6. Cystine, an amino acid saturated with sulfur, gives keratin molecules their brilliance. It is contained in almost all foods rich in protein such as meat, soybeans, cheese and some vegetables. Production of keratin is hindered by stress, harmful chemicals and alcohol abuse, which slow down protein metabolism.
You will also want to use special cosmetics with keratin for additional hair care. Nowadays there are many shampoos and conditioners which formulations are base on keratin. Harmonious combination of natural ingredients in these products can help you reach positive results. They supply hair follicles with keratin and additional nutrients “from the outside” recovering the proper structure of hair and improving the condition of the scalp. Shampoos and other hair care products are particularly useful for weak and damaged hair.
