I’m male with fair skin and a dark, course beard.
Was thinking of waxing my neck and face. Is surgi wax any good? any other suggestions?

Waxing a course male beard by yourself at home is going to be a nightmare… and having it done professionally will not make the task much easier - the hair on the face is tough, and very dense, and the years of shaving can make the hair even harder to remove by methods such as waxing… By all means, the neck could be done easily by a professional, or someone with a bit of experience using a home kit.

Some people have reported success for a while with LASER treatment, but to permanently thin or eliminate your beard and neck hair, Electrolysis is the only worth while option pursuing IMHO…

Good luck,
