I really need to have my back hair removed by lazer - it it safe? Painful? Expensive?

Answer 1

It is very safe, if performed by a qualified technician. Most people report a mild stinging sensation.
It is quite expensive. Most people need a series of treatments over 6 months, so it adds up.
It works best if the skin is quite light, and the hair is quite dark.
It does not work very well on light coloured hair, or on dark skin.
