I dyed my hair a few days ago, I purchased the hair dye and the developer. I really enjoy the smell of the actually developer and was wondering, if I were to put that in my hair for like 1 minute just to get my hair to smell like that, would it damage my hair at all, or not do anything to it?

Also if you can explain to me the purpose of the developer, I'm curious as to what it does.

Thanks guys

I forgot to mention I have 30 and 10 volume in developer.
