I've had multiple nofap streaks and my hair got thicker or at the very least it stopped shedding.
What's even more obvious is that if i binge masturbated, i'd instantly get itchy, greasy scalp and i'd shed like crazy.
There's multiple accounts of people halting hairloss on reddit/nofap
There are also multiple accounts of people claiming they got their ex back with the help of a spell.
