here in my location not dying ones hair is not what the term letting yourself go means. here in my location letting your self go in reference to looks means a person doesnt shower, or do any other personal hygiene, they dont bother changing their clothes, dont bother taking care of their self.

here in the USA whether one dyes ones hair or not is called a personal choice and in some cases a medical issue due to the chemicals in hair dye are not very easy on the body. they cause scalp problems, hair thinning, hair loss, hair turns to brittleness because though it looks good on the outside its actually damaging the hair and scalp. many doctors are now telling their clients to stop using hair dyes because its causing all kinds of problems and health conditions like alopecia, cancers, scalp lesions,

there are also many cultures and lifestyles go holistic rather than use chemicals in or on their bodies.
