If Isis, (ANTM) had a sex change, how come she doesnt have hair on her legs or arms?

If you had a sex change from male to female, would they take the hair glands out of their body?

Isis likely spends $$$ on electrolysis to remove hair. Hair folicals do not have a gland.

you can either shave it or have laser hair removal. also, these men start to take female hormones which probably changes their hair growth along with changing their voice to a more feminine one

The previous answers are correct. It is probably a combo of hormones and electrolysis.
