The hairstyle of students is also given attention by schools and the Ministry of Education. Males are not allowed to have long hair. Some prohibit even girls from having long hair.[51][52] The use of accessories is prohibited for males, while females are sometimes allowed to use simple accessories. Some schools dictate the colour and type of hair accessories that females can be used. All students are prohibited from colouring their hair or having tattoos on any part of the body.
Thailand however has a few international schools which do not require uniforms.
