Looks like she's taking too much of the brows off, i.e towards the inner corners of your eye ( if that makes sense?) Making them too arched. You can grow this back and just use a pencil to fill in the gap whilst they're growing. Just pluck the hairs towards the outer part of your brows, giving them a much nicer shape.
leave them 4-6 weeks to grow out fully. go to a decent beautician. dont have wax if thats what you have tried before. have threading done, its more precise, an they can show you as they do it! also if you want them to look more full or show more, have them tinted. x
Let them grow out fully, then just follow your natural brow shape and pluck stray hairs, dont overpluck! Thats where most people go wrong. Waxing is fine to get rid of all the fluffy bits and as long as they dont get the wax on the main bit of your brow (ie the bit you want to keep!)
Shavata do eyebrow stencils, you choose the shape, stick it on your face and pluck around it, never tried them personally but Ive heard they actually work ok!
Also after youve plucked, to get more definition use a brow pencil, most people who have 'perfect' eyebrows pencil them in to some extent. Just make sure its the right colour
