A Quick Tip for Methylisothiazolinone Free Hair Dye

I have had a couple of people asking me about methylisothiazolinone free hair dye.  The answer is that although I don’t know a lot about hair dyes, I don’t think that many of them contain methylisothiazolinone or methylchloroisothiazolinone in either the colour shade or the activator.  But quite a lot of them also include a conditioner, and this is often preservered with our troublesome friends. 

A good example is the big selling nice’n easy range from Clairol.  The conditioner that comes with the pack is really good, so I wouldn’t advise the majority of people who don’t have a problem with MI/MCI to avoid it.  But if you are unlikely enough to react to them, there is nothing to stop you using another conditioner that suits you when you get to that stage.

This advice of course applies to all hair dyes, not just the Clairol one.  That just happened to be on my desk when the query came in.


I am getting quite a few posts about methyisothiazolinone free products.   Here are few more.
