Hair loss is surprisingly very common. It affects up to at least 50% of women in their lifetime, with an estimated 30+ million women affected by hair loss in the United States alone. While there are many reasons for female hair loss, the most common type of hair loss in women is androgenic alopecia and this tendency can be inherited from either parent.

For men, by the age of thirty-five, two-thirds will experience some degree of appreciable hair loss, and by the age of 50 approximately 85% of men have significantly thinning hair. 95% of male pattern hair loss is due to androgenic alopecia.

Trauma, stress, pollution, genetics, diet, hormones, skin disorders, aging, trichotillomania, major surgery, medication, endocrine conditions that affect thyroid function, iron deficiency, systemic diseases like lupus, scarring, chemical processing, and even wearing certain hairstyles can all contribute to hair loss.
