My Hair is Retarded

I get an e-mail from M:

“Maybe you would know. Ok, I tried to touch up my roots a dark brown colour last night but it did nothing. If anything, my hair is lighter than before. Like, it took off the previous dye or something. Why would that happen? And what kind of dye should I buy?
My hair is retarded. It went back to normal colour. It is really soft though! Lol, so I have to fix it asap. I will try it again tonight and it on double time or something.”

Oh, that sounds fun! I can’t wait for this disaster in the making.
