DIFFERENT TYPES OF THINNING HAIR
Thinning hair in women is surprisingly common. More than 1 in 4 women will experience it at one time or another. While certain lifestyle factors can have an impact on your hair’s thickness, over 90% of all hair loss is the result of genetic factors. So before you start blaming your diet or blow dryer, get to know the science behind hereditary thinning hair in women.
Hereditary hair loss, known as androgenetic alopecia (AGA),is a genetic condition that shortens the time that hair spends actively growing. AGA causes the hair follicles to become smaller. Gradually, thinner, light-coloured hairs, called “vellus” hairs, will replace your large, darker hairs. Women with hereditary hair loss experience a general thinning of the hair, with the most extensive hair loss occurring on the top of the head and along the part.
Temporary hair loss, known as telogen effluvium, happens when stress, diet, a hormonal imbalance, or a traumatic event causes hair follicles to remain in the resting state; this results in increased hair shedding and a temporary thinning of hair across the whole scalp. While the amount of time someone stays in telogen effluvium varies, once the root cause has been corrected, hair should return to its previous thickness.
Alopecia areata, an autoimmune disorder, is recognizable by well-defined patches of hair loss that may happen quickly and lead to complete hair loss. If you have no history of hair loss in your family and are experiencing this kind of hair loss, consult your doctor.
Who’s to blame?
It’s a commonly held myth that genetic hair loss is only inherited from one side of the family. In reality, women can inherit the thinning hair gene from their mother, their father, or from both parents. That being said, if a number of her close relatives have thinning hair, a woman’s chances of experiencing hair loss increase, although it is by no means inevitable that she will experience it.
Not just for men
Incorrectly thought of as only a male concern, both men and women experience thinning hair, but in varying patterns and severity. Men’s hair tends to recede at the hairline and/or they experience hair loss around the crown of the head, whereas a woman’s hair loss usually involves a more dispersed thinning on the top of the head, often noticeable as a widening part.
