* Leg hair: You might start to feel stubble in 1-3 days after shaving. It can take 1-4 weeks for the hair to grow back to a noticeable length.
* Armpit hair: Due to its shorter growth cycle, armpit hair tends to grow back faster. You might notice stubble in 1-2 days, and it could take 1-3 weeks to grow back to a length where you feel the need to shave again.
Keep in mind that these are just averages. Some people experience faster or slower hair growth.
