Tried to dye my hair from blonde to ash brown, but it turned grey!!! :S

My hair is really damaged now! :’( Supposed to wait awhile for hair to recover before dyeing again, but was feeling stressed out from uni and wanted to do something… What random things do you do as stress relief? 

PS: look really horrible from staying up too much these past weeks, so just.. have one eye! (kind of creepy ey?)
