Severe allergy to conventional hair dye :(
I have a really bad allergy to all of the conventional hair dyes on the market currently. I have been using its pure henna dye but it doesnt give me nearly enough coverage for my greys, the colour doesnt last and its an absolute pain to use (4hrs with it sat on my head). Is there any other permanent dyes i could try that dont include the harsh chemicals no ammonia, PPD ect 🥲
