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.
Never one to be uncomfortable with challenging traditional industry norms, Dr. Ziering recognized that women are an underserved community of hair loss sufferers. Female hair loss often goes ignored even by mainstream beauty publications, making it difficult for balding women to get the education and answers they deserve. And yet, hair loss in women is very common, with approximately 30% of women experiencing some amount of thinning hair throughout their lifetimes.
Causes Of Female Hair Loss
Like their male counterparts, inherited genetics is the primary reason, but there are other medical conditions that cause diffuse hair loss in women such as:
- Hormonal changes
- Discontinuation of birth control pills
- Obstetric and gynaecologic conditions such as post-partum and post-menopausal states or ovarian tumors
- Anemia or iron deficiency
- Thyroid disease and the medications used to treat it
- Stress or trauma – surgical procedures, general anesthesia, and severe emotional problems
- Poor nutrition caused by sudden changes in diet, crash dieting, bulimia, protein/calorie deficiency, essential fatty acid or zinc deficiency, malabsorbtion, hypervitaminosis A
- Lupus – a connective tissue disease
- Various medications
- Traction Alopecia or hair loss caused from trauma, excessive tension on hair from wearing hairstyles or braiding that is very tight
The Ludwig System
The central parting of a woman with no hair loss.
Ludwig I-2 I-3 I-4:
The width of the parting gets progressively wider indicating thinner hair along the center of the scalp.
Ludwig II-1 II-2:
Diffuse thinning of the hair over the top of the scalp.
A woman with extensive diffuse hair on the top of the scalp, but some hair does survive.
A woman with extensive hair loss and little to no surviving hair in the alopecia affected area. Very few women ever reach this stage and if they do, it is usually because they have a condition that causes significant, abnormally excessive androgen hormone production.
A woman with a pattern of hair loss that is described as “frontal accentuated”. That means there is more hair loss at the front and center of the hair parting instead of just in the top middle of the scalp.
