Hair loss can affect women of any age, and there are many potential causes. Below are the more common causes of hair loss in young women under 30.

Alopecia Areata

According to the National Alopecia Areata Association(NAAF), about 2% of the population is affected by this disease. Alopecia areata is an autoimmune condition which tends to cause hair loss in scattered circular areas on the scalp.

Alopecia tends to start with small, smooth, circular patches of hair loss on the scalp. From there, the course of hair loss is different for everyone.

Tinea Capitis

A fungal infection of the scalp that is also known as ringworm. This fungus can spread very easily, and it thrives in wet environments. Because of this, people who don’t bath often or remain sweaty for long periods of time are more susceptible.

Androgenetic Alopecia

Also known as female pattern baldness, this is one of the most common causes of hair loss in women. It can start in teenagers, but the chances of hair loss from it increase as women age.  This form of hair loss begins with thinning and shortening of the hair primarily around the forehead and near the temples. Family history of this condition, aging and increases in male hormones are the primary reasons behind this. The best way to find out if you are suffering from pattern baldness is through a blood test.

Telogen Effluvium

This is usually brought on by things like pregnancy, severe stress and other events that cause hormonal shifts in the body. While this condition is very common, researchers do not understand it very well. Hair loss brought on by telogen effluvium is from the hair follicles resting dormant so that they aren’t producing hair. Generally the condition only affects the top of the scalp. This is normally a temporary form of hair loss that corrects itself with time.


Trichotillomania is an impulse control disorder where a person continuously pulling on and playing with their hair, which will cause thinning and bald patches.  Some teenagers do this as a nervous habit, while others may be dealing with major stress or anxiety.

Some people have found success with antidepressants and/or behavior modification therapy.

Other Medical Conditions

There are many other medical conditions that your primary care physician can help with (such as thyroid disease or other conditions) that can be ruled out through basic tests.
