(male) I have noticed my hair really starting to thin over the last 4 or 5 years, about the same time my hairdresser and decided to colour my hair. Can hairdye cause hair loss, and what can I do to reverse the process. If it is the dye, is there a dye you can recommend that is easy on the scalp and hair? Thanks for your help
Any chemicals used on external parts of the hair can cause hair loss if it works its way through the follicle and down to the root. There are many reported cases of hair root damage and hair loss from deep chemical burns from hair dyes. Also, irritation or inflammation of the skin, like as in allergic reactions, can accelerate hair loss in a person who is prone to it.
You may have had the genetic vulnerability to hair loss that has been activated by an external stimulus “reaction to dye”.
