Laser hair removal is actually classed as semi permanent as it does not necessarily kill of the follicle. There is something called electrology which used a tiny metal probe to pass electricity through the follicle killing it. That’s the only way to permanently get rid of it and it is not a fun method!
I’m joking of course, but male pattern baldness is a huge issue and over $1bn is spent in the US each year on treatments. One study has shown that almost 75% of men (and about 60% of women) experience some hair loss by the age of 80.
