okay listen, i still think dabis actual hair colour is red. he has a fire quirk and he hates his dad. he didnt want to look like him so he dyed it! anime touyas hair was also red and i doubt they just tossed a dice and let it be a 50 50 chance for either red or white. hori had a say in this. on the picture on touyas shrine the hair is left blank because colouring it black would reveal too much. he'd look too much like the dabi we know so hori left it blank. now in todays spoilers, the bleach is washing away the black dye and reveals another colour. to show that, hori had to make it blank/white again. to show the difference from black to red. when he's sitting in that chair talking, his hair is dark again. so either, he dyed it black again right away OR it is red and we it's finally portraied dark like it should.
