Hair loss can occur for many reasons. Some of these may include:
-
Age is a common cause not only for men but for women, too.
-
Alopecia is an autoimmune condition (condition in which the body's immune system attacks another site in the body) that is more common in people with Down syndrome. A brief description can be found in our Resource Library at this link. Additional therapies (not mentioned in the brief description) that are being studied include immunotherapy medications. A study
at the University of Colorado is researching these medications in people with Down syndrome.
-
Nutritional deficiencies such as iron, biotin, zinc, or protein.
-
Hairstyles that pull on the hair too tightly.
-
Fungal infections.
-
Thyroid disease.
-
Elevated androgens (a type of hormone that is found in men and women).
-
Toxic substances such as chemotherapy and some other medications.
-
Trichotillomania is hair loss from repeated urges to pull or twist the hair until it breaks off. More information can be found at this link.
The Cleveland Clinic
and the American Academy of Dermatology
both have nice summaries of causes of hair loss. We recommend an evaluation by a primary care provider or dermatologist to review the possible causes and develop a plan of treatment for hair loss.
