I think they are looking very good with blonde hairs. If their nose are big as white girl then i will say they are white girls. But it will cost them more money in this case.
The world has been changed as well as society, laos people had been developed for a while. Since they were come from either western country or original laos. Whether they were living in the city or country, but it won't make any different. They like to be modernize look and all, I guess?
lao girl dye their blonde, i think is just a fashion. doesn't mean if you dye your hair blonde and will change you from being lao. just a fashion, girl just wanna look pretty that's all.
