For the pros : Ingrown sideways growing hair

I’m have electrolysis on my genital area and a week ago I notice an ingrown hair that is growing sideways under the scrotal sac skin. I have another appointment with my electrolygist tomorrow and will ask her about it.

Just for curiosity sake, what is the properer procedure for dealing with such hairs? The said hair in question is about 1/2 inch long.

As I found out that particular hair was already dead. Had to slice the skin open to get it out there.
