Coming soon: The cure for baldness?

Earlier work by the same team found bald men have cells capable of making hair; they have just failed to mature.

It is thought that PGD2 prevents the cells maturing – and stopping it from working would allow hair to grow again.

In tests on lab and on mice, the compound stunted hair growth, the journal Science Translational Medicine reported in March.

‘Blockers’ of the enzyme have been formulated as pills to cure asthma and allergic conditions but it should be possible to turn them into a lotion which could be applied to the scalp.
