What's the best hair removal for upper lip hair on a dark haired person?

amino

I'm 23 and since my 20s my hair growth on my upper lip has changed I seem to have developed a mustache. I have removed it once with nair which I think made it worse when it grew back and then this photo is about a month after bleaching the hair. I'm too scared to remove the hair again until I find out which is best I don't want to cause it to be worse.

I have thick fast growing dark hair
