PP405 shows potential for hair growth by increasing terminal hair and converting vellus hairs, but results are modest and more waiting is needed. It complements existing treatments like minoxidil and finasteride, but won't replace them.

It can be made at home using dried teak leaves and ethanol, though its effectiveness compared to other treatments like finasteride is debated.
