Hair loss in women
Hair is a very important structure cosmetically. Ironically it does not serve much useful function for the body. However, it in a way serves as our passport to the society- how we look is largely decided by the appearance of the hair. - it contributes to the self-image of an individual, thus affecting the personality of a person. This explains the society’s obsession with hair. More money is spent on hair cosmetics and hair treatments than any other ailment!. Advertisements of all types abound in the lay press, often giving false and incomplete information. Hence it is very important to understand the causes of hairloss, and their treatments.

Hair loss is very common in women, more common than one would imagine. Most women feel they are losing hair. Hence , it is important to understand the importance of the hair cycle, and the difference between natural daily shedding, temporary hair loss and permanent pattern baldness.

The normal hair growth cycle and Natural shedding

At full maturity, the human scalp maintains an average of 100,000 hair follicles. Hair is made up of proteins called keratins. Human hair grows in a continuous cyclic pattern of growth and rest known as the "hair growth cycle." Normal hair goes through 3 stages:

Growth cycle of Hair

1. growing phase or anagen: 3-5 years

2. resting phase or catagen: 2-4 weeks

3. falling phase or telogen: 2-4 months

90% of hairs are in growing phase

Hair grows at 1cm per month

50-100 hairs are lost daily during bathing

Hormonal, nutritional factors, stress, deficiency of vitamins, internal diseases affect hair growth

Male hormones are the most important factor for hair growth
Of the 100,000 hairs in the adult scalp, 90% are in growing stage (called anagen ) .The average duration of anagen is 1000 days( 3 years) and scalp hair grows at 1 m every month-which explains why scalp hair can grow to a such a long length! The average daily loss of telogen hairs is 100, which is considered normal.

When does hair loss become abnormal?

Your hair loss may be abnormal if you are losing more than 100 hairs a day. This may result in a general thinning of hair or in a patchy loss of hair over the scalp and other areas-beard or eyebrows.
