I love threading. It gives a really defined, straight shape to your brows (much more than tweezing in my opinion) but without the drama potential of waxing (a brow accidentally being ripped off, burns, skin being taken off with hair etc). It's cheap - £5.50 to get my eyebrows done - and instantly lifts your face.
This is just the start of my Valentines beautification - brows today, hair and tan on Saturday, wax, make up and nails on Sunday. And the likelihood is my boyfriend will literally go in the shower and put on a new tshirt - that will be his Valentine effort. Tsk.
