The National Alopecia Areata Foundation (NAAF) is a nonprofit organization supporting people affected by alopecia areata, an autoimmune disease that causes sudden hair loss. It provides information about the condition, its symptoms and types, available treatments, and related health concerns for patients, families, and medical professionals. NAAF also helps people find doctors, support groups, one-on-one phone support, youth mentoring, and resources for parents, children, and adults.

Its practical resources address treatment and insurance navigation, mental health, wigs, makeup, and everyday confidence. NAAF shares U.S. treatment recommendations, information about FDA-approved JAK inhibitors, and guidance for working with healthcare providers and insurers. The organization also supports research through funding, grants, research participation opportunities, clinical trial information, and resources for researchers.

Community programs include webinars, events, the annual Walk For Alopecia, awareness campaigns, and advocacy initiatives. People can volunteer, fundraise, join support activities, or donate through several giving options. NAAF connects education, practical assistance, community support, research, and advocacy to help individuals and families navigate life with alopecia areata.
