Common questions in this guide

What is Alopecia Universalis?
Alopecia Universalis (AU) is an advanced autoimmune condition where the immune system mistakenly attacks hair follicles, leading to complete hair loss on the scalp and body. Importantly, these follicles become dormant rather than dead, meaning future regrowth is biologically possible.
Does Alopecia Universalis affect anything besides hair?
Because AU is a systemic autoimmune condition, it can cause changes to your nails, such as pitting or ridges. Your doctor may also monitor you for other autoimmune conditions that are occasionally linked to AU.
What treatments are available for Alopecia Universalis?
The current standard of care for advanced alopecia includes new FDA-approved medications called JAK inhibitors. These drugs work by calming the specific immune response that attacks hair follicles, allowing the dormant follicles to produce hair again.
How does Alopecia Universalis impact daily life?
Without eyelashes, eyebrows, or scalp hair, you lose natural protection against the sun, wind, and debris. Daily management includes finding new ways to protect your eyes with glasses and defending your skin from UV exposure with hats and sunscreen.
