There are individual differences in the cycle where hair grows, but it is generally 4-6 weeks.
If you are going to book next time, if you are a type of hair growing up well, you can do it after 4 weeks, otherwise it is fine even after 6 weeks.
Also, if you still have not been able to grow even after 4-5 weeks, you can change your reservation by phone (to postpone later).
There are some conditions where you have very rapid hair growth than average – such as in case of PCOS, you may get treatment in shorter interval than usual case.
