Hair Loss (cont.)

This is a small or localized hair loss area caused by repetitive or persistent pulling or force on hair roots. Tight braids and ponytails can pull hard enough on hairs to make them fall out. If this happens, it's best to choose hairstyles that put less pressure on hair roots. The sooner this is done the better to avoid permanent damage.

This refers to the habit of someone voluntarily pulling at their own hairs or twisting them, sometimes without realizing it. The scalp and eyelashes are often affected. Unlike alopecia areata patches, which are perfectly smooth, hair patches in trichotillomania show broken-off hairs. Treatment is often entirely behavioral: You have to notice that you're doing it and then consciously stop. Severe or resistant cases may require stress counseling with a therapist or psychologist or medical treatment with a psychiatrist. Several antidepressant or anxiety medications have been shown to potentially help with this condition.

Tinea is the medical word for fungal infection, and capitis means head. Tinea capitis is fungal infection of the scalp that for the most part affects school-age children. Tinea capitis is more common in black African or African-American scalps. This condition is rare in healthy adults. Bald spots usually show broken-off hairs. Oral antifungals are needed to penetrate the hair roots and cure the infection after which hair grows back. It is contagious from sharing hats or combs and brushes.

This is an overall hair thinning without specific bald spots or patterns. While this type of hair loss may not be noticeable to others, often the individual will feel their hair is not as thick or full as it previously was. Common conditions in this category are

• telogen effluvium (rapid shedding after childbirth, fever, or sudden weight loss);



• androgenetic or androgenic hair loss ("male-pattern baldness," "female-pattern baldness").
