Should I touch up my Brazilian myself?

Allegra
So today I got a Brazilian wax (I've done it twice before) but there's still some hair left in a few spots. Top of the buttcrack, a little bit just between my asshole and vagina, hairs here and there that I can absolutely tweeze myself. But I've been considering getting the cold sticky self waxing strips just to get the spots I can't reach with the tweezer. What do you ladies think? Too risky?
