i'm asian and i have permed (or almost semi-permed) hair. and it's really not that bad, actually not bad at all. just make sure u do your research and pick a decent salon to do it at. and also be sure to show pictures of what you might want your curls to look like.
this is my real life style of my perm. *pics below*
for the
1st pic, that was the DAY i got my hair permed. notice how super curly it is. and that was NOT how i wanted my hair to look like... i want big curls/waves. but the salon person told me that they NEED to make it super curly because when you wash, it dies out.

please ignore my worn out makeup... i was in the salon from 1 pm to 8 pm.

for the
2nd pic, that was the 3rd day (i believe) after i got my hair permed. i had already washed my hair. notice how much more subtle it is. definitely turning into the results i wanted.
3rd pic, this is like 2.5 months after. it really died down.. but you can still see it. it's more wavy than curly.
4th pic, 3 months after... sort of the same... but you get what i mean.
so yeah, sorry for not having more informative pictures, i was searching through my albums... haha.
it's been about 4.5 months since i got my perm. i'm planning to get a haircut realll soon because well... i'm so weary of it. trust me, having permed hair is a hassle.
hope i was informative.
