Hair Growth Cycle And Hair Loss
The normal hair growth cycle lasts 2 to 3 years. During this phase, each hair grows about 1 centimeter per month. About 90% of the hair on your scalp is growing at any given time. About 10% of the hair on your scalp is, at any time, in the resting phase. After 3 to 4 months, the resting hair falls out and replaces new hair. As part of this cycle it is normal to shed some hair each day. However, some people may experience an illness that causes hair loss.
In the era of a growing list of issues and concerns, hair loss can create additional stress and anxiety. For most people, excessive hair loss is gradual, meaning it occurs over a long period of time. This is specifically true for male-pattern baldness. Hair loss is considered excessive when it results in bald spots or hair that is quite thin. In some cases, hair may fall out suddenly. It is usually caused by a sudden shock – either a physical or emotional shock – to your body.
