i asked the hairdresser did she cut her own hair herself...
lol. and she said no.
and i was kinda surprised. =/

i always tried imagining hairstylists cutting their own hair. lol and i thought they can do it by hook or crook even if it looks super unglam and whatnots. lol. so i finally got my answer. kinda same meaning as 能医不能自医. and i tink it's very sadded. cuz you can't use your own skills for yourself and have to entrust your hair to other people when it's ur niche... yea. and have to waste money. lol.

but maybe there are stylists who will diy la huh... just that i don't know any. haha.
