Physiological hair loss is a natural cyclical phenomenon. A new hair grows in place of the hair that falls out. This is called the hair cycle, which on average repeats 20 to 40 times throughout a person’s life. There are approximately 100,000 hairs on the scalp and a hair has an average life span of 4 to 7 years. Up to 80 hair loss, a day was assumed to be the norm. The above data shows that a statistical person should have full head hair until old age.

However, in practice, at different ages, we encounter excessive hair loss and alopecia. It is influenced by endogenous and exogenous factors. The main problem is hair loss caused by exogenous factors, about 70% of people are affected. Endogenous factors are mainly genetically determined hormonal and metabolic disorders. We encounter exogenous factors in our everyday life, including drugs, chemicals, inadequate diet, cosmetics, atmospheric pollution, solar radiation, and emotional stress. They damage the hair follicles to varying degrees, which leads to excessive hair loss and alopecia. In people with a genetic predisposition to baldness, the action of exogenous factors contributes to the aggravation of the disease.

The toxic effect of the above-mentioned factors is based on the release of an excessive amount of free oxygen radicals in the body. This leads to what is known as oxidative stress.

We can divide hair growth measures as follows:

1) substances that improve blood circulation,

2) nutrients,

3) biochemical substances e.g. 5 alpha-reductase inhibitors,

4) Plant bio-stimulants such as KAMIWAZA.

When we use the first three measures, works well if the specific substance matches the cause of baldness. While KAMIWAZA works by regenerating cells damaged by free oxygen radicals and therefore is effective regardless of the cause of the damage to the hair follicle cells.

The effects of using hair care products always depend on the condition of the hair follicles, which, after hair loss, undergoes miniaturization and disappears with time. In the case of young people who have recently lost their hair and whose hair follicles are still active, the first shoots should be visible after 3 – 4 weeks. People who lost their hair 10-15 years ago need to be more patient. Noticeable changes will probably take place after a year. Regardless of hair regrowth, the condition of the scalp improves.
