Smelly hair and scalp can result in embarrassment, avoidance of social situations and difficulty with necessary activities such as going to work or shopping for groceries. Although scalp and hair odors are rarely a cause for medical concern, symptoms that persist or worsen might require medical evaluation. Fortunately, most cases of smelly hair and scalp are treatable or preventable through lifestyle changes or use of medication.
Features
Hair or a scalp that smells might also have other issues, such as an oily or greasy appearance, flakes, itchiness and sweating. In some cases, people might notice other symptoms, such as dandruff. The odor might worsen after exercise, during hot weather or a stressful activity or experience.
Identification
People with smelly hair or scalp might notice an odor while performing grooming activities, such as hair brushing or getting dressed, or when washing linens, such as towels or pillow cases. In some cases, the person does not notice the odor, and the smell is pointed out by a family member, friend or coworker. According to MayoClinic.com, dermatologists or general physicians diagnose the causes of a smelly scalp or hair by conducting a physical exam, taking a medical history and ordering blood or urine tests if medical conditions, such as a thyroid problem, are suspected as the cause of the odor.
Causes
Poor hygiene is not the only cause of a smelly scalp or smelly hair, although infrequent showering or washing of the hair could result in these symptoms. Using chemical treatments on the hair, such as relaxers, colors or perms, might also contribute to smelly hair and scalp. Personal behaviors, such as smoking, might also contribute to hair and scalp odor. Excessive sweating might result from genetic conditions, intense physical activity or nervousness, and can lead to smelly hair and scalp. An overgrowth of yeast on the scalp, or bacterial or fungal infections might also result in a smelly scalp or smelly hair.
Treatments
According to the American Academy of Dermatology, doctors treat smelly hair or scalp resulting from excessive sweating with topical antiperspirants and oral medications, such as glycopyrrolate and propantheline bromide, that reduce sweating. Doctors might prescribe antifungal or antibiotic medications for infections that cause hair or scalp odor. Regular washing with a mild shampoo can also help reduce hair and scalp odor; some people might consider making their own shampoo made of baking soda and water to aid further in treating smelly hair and scalp.
Prevention/Solution
Consider showering immediately after exercising or spending time outdoors, and if necessary, take more than one shower daily to help reduce odors or prevent them from developing. Avoid foods, such as garlic and onions, that can worsen bodily odors. Use relaxation techniques, such as meditation or massage, to reduce stresses that can trigger sweating. Thing about using linens made of natural fibers, such as cotton and silk, to help prevent smelly scalp and hair from developing while sleeping.
