What Diseases Are Associated with No Hair Growth?

Alopecia areata is a condition where hair falls out in small patches, and it can sometimes lead to complete hair loss on the scalp or body. This happens because the immune system mistakenly attacks the hair follicles, where hair grows.

Key Points:

• Immune System: The body’s immune system attacks hair follicles, causing hair loss.
• Hair Loss Patterns: It can cause patchy hair loss, total loss on the scalp, or even loss of all body hair.
• Treatment: There are treatments available, but they don't always work for everyone. Some people may see hair regrow on its own.

Sometimes, people with alopecia areata may see their hair grow back, but it can fall out again. Researchers are still studying why this happens and how to help hair grow back more reliably.
