a. Lack of Proper Nutrition:

Hair is made up of a protein called Keratin. For the hair to grow you need to have proteins and iron along with essential vitamins. Ninety Percent of the hair is always in a growing phase, it takes two to three years for the hair to grow and then it enters a resting phase of three months. After that hair sheds and new hair takes its place. So to allow the hair growth you need the right blend of protein and iron. A balanced diet will surely give you healthy hair.

c. Hormonal Changes:

Hair fall or alopecia happens due to high or low hormone levels. Hormones regulate all the organs in the body. Estrogen, progesterone, testosterone are the active hormones in a woman’s body. Female pattern of baldness occurs when the dihydrotestosterone (DHT) levels increase in the scalp.

The dihydrotestosterone (DHT) is a byproduct of testosterone and it is produced in the follicles where enzymes convert testosterone into DHT. Sometimes genes are responsible in converting testosterone into DHT readily leading to baldness. Also when levels of female hormones decrease the male hormones become active leading to hair fall.

Also progesterone that is secreted in the body during ovulation decreases during menopause. The body produces adrenal cortical steroid called androstenedione. This steroid has male hormonal qualities that cause hair fall.
