Hair dye side effects
I want to know that if an ammonia free hair dye has any side effects on us or not or is it safe to use?

Thanks for the query. If it suits you, its probably good for use to you. Before a hair dye application, a patch test should be done on a smaller area to check for allergic reaction. You should wait for atleast a week and preferably 2 weeks to rule out an allergic tendency with a given dye. Hope it helps you.
