This is the wig I used for the practical exam in the national exam in March 2025. I successfully passed the practical exam with this. It still has a good amount of hair, considering I used it for a year, and the perm is still there. I think it depends on the user, but since it's been used for a year, the perm might have faded a bit, so you might want to get it permed again. I had a teacher at school do the cut, perm, and root flattening for me, and then I purchased it. If you're interested, feel free to ask any questions.
