The hair root is encased in a follicle that is nourished by blood vessels. A youthful scalp contains approximately 100,000 to 200,000 hairs. Normally, an average person loses about 50 – 100 strands daily and the average hair grows only half an inch per month. Excessive loss or absence of hair is called as ‘alopecia or balding’. Common causes of hairfall and early graying are – inadequate nutrition, heredity, stress, high fever, hormonal imbalance, side effect of some medication (cytotoxic agents, anticoagulants, antithyroid, drugs and oral contraceptives) and certain illnesses (like anemia, thyroid disorders, autoimmune disorders, etc.) alopecia areata appears as sharply defined non – inflamed bald patches in the scalp. Alopecia totalis is a condition where there is total or complete loss of the scalp hair and alopecia universalis signifies a complete loss of hair all over the body.
Avoid massaging the scalp vigorously. Massage the scalp gently with the fingertips. This increases the circulation and thus helps provide proper nutrition (through a blood circulation) to the hair follicle. Comb or brush the hair when it is dry since grooming it when wet can lead to breaking of the hair. Do not blow – dry the hair on a high setting
