Minoxidil is highly toxic to cats, and even small amounts can be fatal. The user decided against using topical minoxidil due to the risk to their cats and considered oral minoxidil and ketoconazole shampoo as alternatives.
Ketoconazole can slightly improve hair density and is best used as an adjunct to treatments like finasteride and minoxidil. It helps with scalp health but won't stop androgenetic alopecia on its own.
The conclusion of the conversation is that the user, PirateBeastBaby, had good results with microneedling for hair loss after using oral finasteride and topical minoxidil 20 years ago. They believe that microneedling was the gamechanger for their hair growth.
A user reversed hair loss using 10% sulfur soap, which reduced scalp inflammation and possibly demodex mites. The user did not use finasteride or minoxidil, suggesting inflammation may contribute to hair loss.
The post discusses using 2% ketoconazole shampoo as a competitive androgen receptor antagonist for hair loss, applied for 1.5 hours daily. The user questions its effectiveness and potential benefits compared to finasteride and minoxidil.
