Where can I buy hair bleach in Kunming? I've been to some cosmetic shops and checked out carrefour on nanpingjie, but all I can find are various brown/black dyes.

Exactly, where? I checked Walmart and there's nothing as well... I only saw some 金黄色染发剂 in taobao...

Do Asian hair types bleach differently? I think that they might. If so, and if you don't have Asian hair type, be careful.
It is rare to see a Ch person with bleached hair, although in Japan it is more common.

Why don't you order the hair dye online? Browse the Google you will find many sites you can select from a large collection.

Hair color like Nice'n Easy or Color Silk might be in an expats brought from home supply. Got a couple blonde shades. You might advertise on GOKM classifieds for some or look at those who are selling out to leave Kunming and call them.

I have a hair bleach from Europe, Poland. I wanted to bleach my hair, but then I changed my mind and gone for dark brown instead. I'll sell for 70 kuai.
