The timing and pattern of pattern baldness is also different in men and women. While men tend to start losing hair in the 30s and 40s, hair loss begins in the 40s or 50s in women, though it can occur as early as the 20s. And while men first lose hair in the front and at the top of the head, women's hair thins diffusely throughout the scalp.
Until recently, women have been reluctant to seek treatment, but hair restoration surgeons say that women make up more and more of their practices.
Myth: Poor Blood Flow Causes Pattern Baldness
This myth has been used to sell hair loss products as bizarre as a device that allows you hang upside down in your closet overnight in order to restore blood flow. But as Paul McAndrews, MD, a board-certified dermatologist and hair restoration surgeon and a clinical professor at the University of California School of Medicine, explains, "Blood supply is excellent in the balding region, which is why hair transplant works so well."
Myth: Pattern Baldness is Caused By Hair Mites, Plugged Follicles, Vitamin Deficiencies
Other manufacturers claim that pattern hair loss is due to a hair mite called the demodex mite that can be removed with certain shampoos, or to plugged hair follicles, which can be unplugged with a shampoo or laser comb.
Dr. McAndrews says there's no evidence to support either of those theories. "The dermodex mite has been seen for centuries on hair follicles on face and scalp. If the mite contributed to hair loss, my beard hair would be gone."
