After a couple of nights my pillow takes on a brownish 'stain' where I tend to rest my head. I wrecked my brain to try and work out what it is (especially since I haven't worn make up for a long time) so all I can think is hair dye (dark brown).
But surely I would have heard of this 'phenomenon' before if this is a thing. On the other hand, surely I can't be the only person whose box hair dye stains the pillow even after it's been several washes since I coloured my hair.
Anyone?
