How is androgenetic alopecia diagnosed in women?

What causes androgenic alopecia in females?
Androgenetic alopecia (AGA), also known in women as female pattern hair loss, is caused by androgens in genetically susceptible women and men. The thinning begins between ages 12 and 40 years, the inheritance pattern is polygenic, and the incidence is the same as in men.
What is androgenic alopecia female?
It’s called androgenetic alopecia, or female (or male) pattern hair loss. In women, androgenetic alopecia begins with gradual thinning at the part line, followed by increasing diffuse hair loss radiating from the top of the head. A woman’s hairline rarely recedes, and women rarely become bald.
Can androgenic alopecia be diagnosed?
Diagnosis is clinical and is based on recognizing the pattern of hair loss. Possible treatments are oral finasteride and/or topical minoxidil solution or foam for men, and topical minoxidil solution or foam for women.
What causes high DHT levels in females?
Luteinising hormone in the blood then travels to the Leydig cells in the testes in men (or ovaries in women) and stimulates them to produce more testosterone. As testosterone in the blood increases, more of it is also converted to dihydrotestosterone, resulting in higher levels of dihydrotestosterone as well.
How do they diagnose androgenetic alopecia?
The diagnosis is usually based on a thorough history and a focused physical examination. In some patients, selected laboratory tests or punch biopsy may be necessary. Topically administered minoxidil is labeled for the treatment of androgenetic alopecia in women.

In men, this condition is also known as male-pattern baldness. Hair is lost in a well-defined pattern, beginning above both temples.

How is alopecia diagnosed?
A doctor may be able to diagnose alopecia areata simply by looking at the extent of your hair loss and by examining a few hair samples under a microscope. Your doctor may also perform a scalp biopsy to rule out other conditions that cause hair loss, including fungal infections like tinea capitis.
