Signs & symptoms
Hairs tend to break mid-shaft after minimal manipulation. You may have shorter hair on some parts of your scalp. A white node on your hair may indicate splits in the hair. You also might observe breakage at the junction of processed and new hair growth close to the scalp, especially at the back of the head and nape of the neck. In addition, you may experience itching, redness, and soreness on your scalp.
Diagnosis
the diagnosis of TN is based on the patient's history and his/her physical examination. The dermatologist will examine the hair and the scalp of the patient in order to determine the severity of the disorder.
Treatment
Heat should not be applied to the hair more than once a week. Protect your hair with conditioning shampoos and moisturizing conditioners. Avoid use of hair products containing alcohol.
