Most people normally shed 50 to 100 hairs a day. But with about 100,000 hairs in the scalp, this amount of hair loss shouldn't cause noticeable thinning of the scalp hair. As people age, hair tends to gradually thin. Other causes of hair loss include hormonal factors, medical conditions and medications.
Hormonal factors:
The most common cause of hair loss is a hereditary condition called male-pattern baldness or female-pattern baldness. In genetically susceptible people, certain sex hormones trigger a particular pattern of permanent hair loss. Most common in men, this type of hair thinning can begin as early as puberty.
Hormonal changes and imbalances can also cause temporary hair loss. This could be due to pregnancy, childbirth, discontinuation of birth control pills or the onset of menopause.

Medical conditions:
A variety of medical conditions can cause hair loss, including:
1. Thyroid problems: The thyroid gland helps regulate hormone levels in your body. If the gland isn't working properly, hair loss may result.

2. Alopecia aerate: This disease occurs when the body's immune system attacks hair follicles — causing smooth, roundish patches of hair loss.
3.Scalp infections: Infections, such as ringworm, can invade the hair and skin of your scalp, leading to hair loss. Once infections are treated, hair generally grows back.
4. Other skin disorders: Diseases that can cause scarring, such as lichen planus and some types of lupus, can result in permanent hair loss where the scars occur.
5. Menopause: Many women suffer from hair loss when going through the menopause. Every person naturally loses between 50 and 100 hairs a day. If you begin to lose more than this, you may notice areas of baldness on your scalp, clumps of hair coming out when you wash or brush your hair, or thinning of hair around the front and sides of your scalp.
Hair is made from keratin, the same material as nails. This is produced by cell structures known as hair follicles lying beneath the scalp and the hair that people wash, brush and style is actually the dead secretions from these follicles. Individual strands of hair can stay on the head for up to six years before falling out.

6. Telogen Effluvium: Telogen Effluvium (TE) is probably the second most common form of hair loss dermatologists see. It is a poorly defined condition; very little research has been done to understand TE. In essence though, TE happens when there is a change in the number of hair follicles growing hair. If the number of hair follicles producing hair drops significantly for any reason during the resting, or telogen phase, there will be a significant increase in dormant, telogen stage hair follicles. The result is shedding, or TE hair loss.
