* Stubble (slight prickliness): Can appear within a few hours to a day.
* Visible Hair (short hairs): 1-3 days.
* Noticeable Growth (longer, more visible hairs): 1-2 weeks.
* Full Regrowth (to original length before shaving): 2-4 weeks or longer, depending on individual hair growth speed.
Keep in mind these are estimates. Some people might see faster or slower regrowth than others.
