The recent Annual meeting of the International Society of Hair restoration Surgery saw discussion of upcoming medications to treat male pattern hair loss. In particular we were intrigued to understand that different versions of prostaglandins (chemicals involved in inflammation) have opposite effects on hair growth! Some prostaglandins have recently been shown to inhibit hair growth, whereas others are well known to stimulate hair growth. Perhaps the most exciting part of the research is that some medications currently being developed to treat asthma via inhibiting specific prostaglandins could have an unexpected benefit in stimulating hair regrowth in balding males. These new compounds are still a couple of years away but may turn out to be the next generation of medicines that positively affect balding.
