The head completely covered with hair has an average of 100,000 to 150.00 hairs. The average lifespan of a hair follicle is between 2-7 years. At the end of this period, a new hair starts to grow from the hair root and the previous one falls out. Human hair is made up of a protein called keratin. Keratin is a durable substance found in skin and skin appendages, such as nails and hair. The color of the hair is completely inherited from the parents. Hair color depends on the thickness of the hair and the quality and quantity of the color material. Hair greying shows hereditary characteristics. The growth rate of the scalp is about 1 mm in 3 days. An average of 100-150 hairs are fall out per day in a normal person, and a new one begins to grow in its place. The number of hair follicles is less in redheads and more in blondes. While a baby has 1000 hair follicles per square centimeter at birth, this number drops to 600 in a 25-year-old person. It is considered normal if 100-150 hair fall out a day. A new strand of hair comes out in 6-10 weeks. New hair can grow from each hair follicle 20 times in a lifetime. The growth rate of hair is higher in men until puberty, and in women in adulthood. 15 – 30 years are the ages when the growth rate is the highest. New hair grows faster than old hair. A strand of hair grows approximately 0.3 mm per day, 1 cm per month, and 12 cm per year. Although the diameter of a single strand of hair differs from person to person, it is between 0.05 and 0.09 millimeters.
A hair has three phases throughout its life:
- Growing and maturity phase (anagen phase): Lasts for three years or sometimes more.
- Regressing phase (catagen phase).
- Resting phase (telogen phase).
