In this section we explore the complex topic of genetic hair loss (androgenetic alopecia). We will examine its causes, classification, diagnosis, and treatment for both men and women. If you have concerns about your hair loss, this information will help, but it is always best to be examined by a board certified hair loss specialist. You can set up an in-person consultation with one of our board-certified physicians or you may submit a photo consultation if you cannot visit our NYC facility.

Hair Loss in Men

Male pattern baldness (androgenetic alopecia) is determined by three interdependent factors: genes, hormones, and age.

The genetics for hair loss can be inherited from either the mother’s or father’s side of the family. It is caused by the effects of androgens on susceptible hair follicles. Most men will experience some degree of hair loss as they age, with more than half displaying signs of genetic baldness by the time they’re in their 50s. View this chart to see how the incidence of male pattern baldness increases with a person’s age.

Read further into the section on Hair Loss in Men, where we explore the causes of genetic hair loss, the classification of male pattern baldness, how it is diagnosed, and what treatments are available.

Hair Loss in Women

Genetic hair loss affects about 30% of women in their lifetime. Because it tends to present as diffuse thinning over the entire scalp, and because women generally do not lose their frontal hairline (as men do), the hair loss may not be as noticeable, particularly in its early stages. Women generally lose hair gradually, with the rate accelerating during pregnancy and at menopause.

Women’s hair loss can also show seasonal variations and is more easily affected by hormonal changes, medical conditions, and external factors compared to hair loss in men.

Read further into the section on Hair Loss in Women, where we explore the causes of female genetic hair loss, classification using the Ludwig Classification system, how a physician diagnoses women’s hair loss, and how it can be treated.
