MALE PATTERN BALDNESS
- The most common type of hair loss in men.
- It includes either:
> a receding hairline
> hair loss at the crown
> or both
CAUSES
- Here hair follicles are genetically sensitive to dihydrotestosterone (DHT).
- DHT is a by-product of Testosterone.
- Hair follicles sensitive to DHT begin to miniaturize
- shortening the lifespan of each hair follicle affected
- Eventually, these affected follicles stop producing hair.
FEMALE PATTERN BALDNESS
- Uniform thinning across the scalp
- With a preserved hairline.
- The crown may be affected
- But hair loss rarely proceeds to baldness as in men.
CAUSES
- Aging
- Changes in the levels of androgens (hormones that can stimulate male features)
- Family history of male or female pattern baldness
- Heavy loss of blood during menstrual periods
- Certain medicines, such as estrogenic oral contraceptive
