Causes of Male Pattern Hair Loss
DHT may contribute to the shortening of growth phase of hair follicles, causing them to shrink until there are fewer visible hairs left on the scalp.
The Anagen Phase
This is also called the active growth phase. This phase continues anywhere from 2 to 6 years with the average hair growing for 1,000 days – about 3 years. The longer the hair stays in this phase, the longer it grows. Anything short of 2 years results in balding. Approximately 80-85% of all hairs are in the Anagen Phase at any given time.
The Catagen Phase
This is the regressive or transitional phase. It lasts for a period of 2 to 3 weeks, during which the hair stops growing but is not yet shed. Between 3 and 4% of our hair is in this phase at any given time.
The Telogen Phase
This resting phase continues for approximately 100 days (3-4 months), at the end of which the hair falls out and a new hair begins to take shape. About 10-13% of our hair is in this phase at any given time. When more hair than that enters and remains in this phase, the result is extensive hair loss.If, over a long period of time, hair cannot regrow as fast as it is being lost, it’s time to consider hair growth remedies.
The Stages of Male Pattern Baldness
The first sign of the onset of Male Pattern Hair Loss is when frontal recession begins to appear in the hairline.
Over time, these recessions become larger and much more noticeable, and the hairline moves further back.
Independently or at the same time frontal recession is occurring, a thinning area may appear on the crown which gradually increases in size.
The final stage of Male Pattern Hair Loss is when the hair is lost completely from the crown and frontal region, and leaving a familiar horseshoe shape.
