Normal hair growth

About 90% of the hair grows all the time, and the period required for hair growth may range from two to six years, while the remaining 10% of the hair is in the resting phase for a period that may extend from two to three months, and then this hair falls out with the end of the rest period.

When the hair falls out, new hair grows from the hair follicles to start a new growth cycle from the beginning, where the head hair grows between 10 - 15 millimeters every month, however, as the person gets older, the pace of hair growth begins to slow down.

Most often, the phenomenon of hair loss is the result of the natural growth cycle of hair, falling at a rate of 50-100 hairs per day is quite normal.

2. Hair loss and hereditary baldness

This phenomenon is known by its scientific name (androgenetic alopecia / Calvities), which is the most common cause of hair loss, as it is transmitted genetically from the mother or father.
