How many laser hair removal sessions are usually recommended?

Nice to meet you. I have been shaving my hair with a razor, but it has irritated my skin and even caused ingrown hairs, so I have decided to go get laser hair removal treatment.

However, I heard that it doesn't finish in one session due to the hair's growth and resting phases. So, I am writing this post to ask how many laser hair removal sessions are recommended in total.

I plan to treat my underarms and calves, and I think it would be easier to set a budget if I knew the approximate recommended number of laser hair removal sessions before booking a consultation. Basic packages are usually sold in units of 5 sessions; will the hair become noticeably thinner and the density significantly reduced just by completing this standard recommended number of sessions? Or is it common for significantly more sessions to be recommended depending on an individual's hair type and thickness?

Usually, the recommended number of laser hair removal sessions varies slightly from hospital to hospital.

On average, how many sessions and at what intervals does it take to resolve the issue? Please let me know the recommended total number of laser hair removal sessions required to completely eradicate the hair, as well as some tips for getting thorough treatments!
