Trichorrhexis nodosa is a problem in which thickened or weak points (nodes) along the hair shaft cause your hair to break off easily.
Trichorrhexis nodosa can be an inherited condition.
Certain things you do to your hair such as blow-drying, over-brushing, perming, or excessive chemical use, appear to trigger the condition.
In some cases, trichorrhexis nodosa is caused be an underlying disorder, such as:
Your hair may break easily or it may appear like it is not growing.
In African Americans, looking at the scalp area using a microscope shows that the hair breaks off at the scalp area before it grows long.
In White, the problem often appears at the end of a hair shaft in the form of split ends, thinning hair, and hair tips that look white.
The health care provider will examine your hair and scalp. Some of your hairs will be checked under a microscope.
Blood tests may be ordered to check for anemia, thyroid disease, and other conditions.
If you have a disorder that is causing your trichorrhexis nodosa, it will be treated.
Your provider may recommend measures to reduce damage to your hair such as:
Improving grooming techniques and avoiding products that damage hair will help correct the problem.
This condition is not dangerous, but may affect a person's self-esteem.
Call your provider if symptoms do not improve with changes in grooming and other home-care measures.
