The hair is commonly known as the "crowning glory." Many people go to great lengths to style and cut their hair to fit the latest trends. Unfortunately, certain underlying conditions can cause people to lose their hair. For instance, a mental illness, premature aging and a fungal infection can lead to hair loss. Fortunately, the diseases that cause people to lose hair have specific treatments.
Trichotillomania
MedlinePlus states that trichotillomania is a condition in which an individual purposefully twists and pulls at her hair until it breaks. Signs of trichotillomania include hair loss, bald patches on the head, frequent pulling or tugging of the hair. Other signs include eating the hair, intestinal blockage, and feeling relief or pleasure after pulling the hair.
The cause for trichotillomania is not clear. MedlinePlus says that it typically affects 4 percent of the population. Medications such as selective serotonin reuptake inhibitors and naltrexone may be used to manage trichotillomania symptoms. Sometimes, behavior therapy can also be used to manage this condition.
Progeria
The Mayo Clinic says that progeria is a genetic condition that typically occurs within the first two years of life. It is a type of premature aging in which its sufferers present with such symptoms as hair loss, delayed growth, aging skin and joint stiffness. Progeria can also lead to hip dislocations, a high-pitched voice, a small jaw and a large head. A beak-like nose, prominent eyes and loss of fat or muscle are other signs of progeria.
An alteration in the gene lamin A is to blame for progeria. No cure exists for progeria. Taking low-dose aspirin and drinking high-calorie dietary supplements can help manage progeria. Sometimes, a feeding tube, and physical or occupational therapy is beneficial to managing progeria.
Ringworm of the Scalp
Ringworm is another disease that can cause individuals to lose their hair. The Mayo Clinic says that ringworm of the scalp is medically known as tinea capitis. Specific signs of ringworm include hair loss, round patches of skin above the scalp, fragile or brittle hair that is easy to pull out, and painful areas of the scalp.
Fungal infections lead to ringworm of the scalp. Simply touching a contaminated person, object or animal can quickly spread the disease. Medications such as griseofulvin and terbinafine hydrochloride can be used to manage ringworm of the scalp.
