If you can’t make it to get your eyebrows threaded, definitely keep them up by tweezing them yourself. I don’t wax or thread my eyebrows myself, I go to the threading salon, but I do keep them up by tweezing any hairs that start to grow outside my natural shape (especially underneath). By tweezing you can keep your brows clean and manicured until you can make it to the salon. I also fill them in with a brow powder. You can watch my YouTube video on how I do them here. Good luck!
