The brain resists updating its perception of gradual appearance changes, like hair loss, due to its preference for stability and reliance on an internal model. This delay in perception can make changes feel sudden once the brain finally updates its model.

A person had three hair transplant surgeries using 7,600 grafts from scalp, beard, and chest, along with finasteride and minoxidil. Reactions are mixed, with suggestions for alternatives like hair systems or scalp micropigmentation.

A 21-year-old experienced significant hair regrowth using oral finasteride for 7 months, initially with minoxidil but later stopped due to inconvenience. He had no major side effects, except a temporary increase in sex drive, and plans to continue finasteride.

Cialis is used to manage erectile dysfunction caused by finasteride and dutasteride, with mixed results. Some users report improvement, while others consider stopping the medication due to side effects.
