Types of Hair Loss
Age-Related Hair LossAlso known as involutional alopecia, this type of hair loss is very common. Hair growth naturally slows down as we get older, so most people notice their hair thinning over time.
Male or female pattern baldness is a genetic form of hair loss often related to hormones called androgens. While men may start losing hair as early as their teens or 20s, women usually notice their hair thinning during their 40s.
There are a number of less common types of hair loss, including alopecia areata (patchy hair loss in children and young adults), alopecia universalis (hair loss all over the body), and scarring alopecias, which result from physical trauma.
