The Alopecia Help Collection

Your immune system helps hair grow — but it can also interrupt growth or damage follicles. Discover the hidden community of cells around each hair follicle, and what new research reveals about alopecia areata, scarring hair loss and stress.

Could dental infections have a surprising connection to alopecia areata? A newly published paper describing three cases of hair regrowth following dental treatment has brought my two professional worlds together in an unexpected way. As a dental surgeon specialising in hair loss, I found this one particularly intriguing.

If you have recently been told that you have androgenetic alopecia, you may be wondering why this has happened now - and whether menopause or testosterone is to blame.
