Losing your hair may cause you to feel embarrassed and self conscious about your appearance, especially if it happens suddenly. Hair loss can occur anywhere on your body that hair normally grows, although it may be more noticeable on your scalp and face. According to the Mayo Clinic and the National Library of Medicine, causes of hair loss behind your ears include lifestyle factors and infections.
Androgenetic Alopecia
Women may experience androgenetic alopecia (female pattern baldness) along the sides and crown of the head, which can cause hair loss behind the ears.
Chemicals
Using chemical treatments on your hair such as hair dyes or relaxers may result in thinning of your hair or hair loss, including behind your ears.
Pulling
If you habitually pull or twist your hair, you may experience hair loss behind your ears without realizing you are doing any damage.
Ringworm
Hair loss behind your ears may be caused by ringworm, which is a fungus that can grow on your skin and scalp in the form of a circular rash.
Scalp Disorders
Disorders of your scalp, such as eczema, psoriasis or lichen planus may cause temporary hair loss anywhere on your scalp and behind your ears.
Styling
Wearing your hair in styles that results in significant traction, such as braids or pig tails may cause hair loss behind your ears.
