The three stages of the hair development cycle are anagen, catagen, and telogen. Hair can grow to be several years long during the anagen phase, when hair cells proliferate in the hair bulb. The resting period, known as the telogen phase, can extend for several months, while the catagen phase is a transitional phase that lasts a few weeks. The hormones Hair development is regulated by male hormones like testosterone and dihydrotestosterone. Male hormone levels are modest in women, but they can occasionally become unbalanced and lead to excessive hair growth. Diet: Hair development may be impacted by a lack of certain nutrients, including folic acid, iron, zinc, fatty acids, selenium, and vitamins D, E, and A. It’s crucial to eat a healthy diet high in protein. ‘Systemic’ refers to the fact that hair growth may be triggered by a hormonal imbalance or a physiological factor. Male hormones, which are produced in the ovaries as a precursor to female hormones, are present in trace amounts in all women. Excessive hair growth can occasionally be a sign of an imbalance in the levels. About 5 million hair follicles are present in humans at birth. These are tiny skin pockets from which hair emerges. The scalp has about 100,000 of these follicles. Individuals with round follicles have straight hair, while those with oval follicles have extremely curly hair.
Hair roots, which are composed of protein cells, are found inside each follicle.
