Information about hair
- The normal rate of hair loss is 50-100 hairs a day (having 100.000 hairs on the scalp on average, then almost 10.000 of them are in the Telogen Phase and 1% of those -100 hairs-can be daily released from hair follicles)
- The number of hair follicles on our scalp is genetically predefined and reduces during one΄s lifetime
- Hair follicles need almost 6 months to replace a released hair with a new one
- Each hair follicle produces approximately 20 hairs during its lifetime
- Each hair can have a lifetime up to 7 years
- Hair grows more than ½ inch per month on average, with a slightly faster rate for women and a slightly slower one for specific categories – old aged, chronic patients etc
- Many of our hairs may grow even more than 1m in their lifetime
- People with red hair have approximately 90.000 hairs on scalp, fair -haired 140.000 hairs and dark or brown haired fluctuate inbetween
- The most qualitative hair growth takes places from puberty to the age of 30. As man ages, hair growth rate decelerates
- The pigment Melanin defines hair colour. There are 2 types of melanin: Eumelanin pigments black and brown hair and Pheomelanin pigments blond and red hair
- Hair gets gray or white when cells that produce melanin decrease or stop its production
- During summer, hair growth rate accelerates and hair grows faster: high temperature increases the speed of reactions and operations in hair follicles
- During day, hair growth rate is more intense
- Healthy hair is characterized by increased flexibility: if streched, it can elongate by an additional 30% of its length without breaking
