I have benefited from this. I have used it entirely for hair removal. Job 1 had unlimited leave so I just took it. Job 2 had unlimited sick leave, on a trust policy, so again I just took it -- it is a medical need. Job 3 I negotiated 10 days per year transition leave. (Accumulating if not taken)

I know also a couple of companies in Australia offer a lifetime 6 weeks transition leave. Also a few offer like a $500 "you need to replace your wardrobe" stripend.

This is why I have been able to do 6 hours of electro every week. And why I could travel to another city for laser (local place was systematical transphobic).
