Did you know that dying your hair is prohibited in Thai schools? The hair is seen as part of the uniform, you see. Glasses too should not have bold colours, the frames must be black or of a neutral colour.
Knowing this it is easy to understand why the girls want to dye their hair as soon as the summer holidays start. Then they can enjoy their different hair colour for almost three months, after which they have to dye it black again in order to go back to school.
It is such fun to see them enjoy dying their hair. They often help each other or the mothers do it for them. Afterwards they are very proud of their new colour and they enjoy it very much.
