Does anyone have good advice on wigs. I was pressured into getting my haircut again by my transphobic parents 

The key is to something that fits your face shape. You need to take into account the size of your head too. Sorry that your parents may you cut it again. Hugs

You need something that looks natural. Real hair wigs do but are very expensive, microfibre wigs can look very natural and are cheaper. Find a nice style that isn't going to be high maintenance (you can't style synthetics the same way and curls/waves will come out). Chose a good colour that matches your skin tone, and as Mariah says a style that suits your face. It needs to be comfortable enough and allow your scalp to breath so you don't get sweaty. Keep it well maintained, brushed, washed and conditioned.
