Do I need to shave every-time my armpits hair is noticeable?

PrinceOfCrows
I am Muslim so both males and females have to shave their armpits, privates, and clip our nails, with in a 40 day time period. But my sister said I should shave every-time my hair starts to get fuller.

I know body hair can be nasty looking and unhygienic, but I am not married so I don't need to look my best and I am okay with my hair.

Should I keep it low or keep waiting until the 40 days are up?
