What tests can help to differentiate between reversible and non-reversible causes for hair loss?

Doctor's Answers 1


Non-reversible hair loss is usually due to scarring of the hair follicles from either infection, infiltration or inflammation.

The most important test to diagnose the above is a scalp biopsy. A scalp biopsy is best performed by a dermatologist.

Hope this helps!
