Remove hair color residue from the skin

So you can remove residues from hair colour remove on the skin well: I stain my hair every 3-4 weeks (blue-black). Sometimes the contours of the skin are then darkened. Since I sweat a little at night due to the menopause, it also happens that the palms - which are pushed under your head during sleep - are already quite darkly discolored. To remove, I take a half, freshly sliced ​​lemon or lemon slice. Then rub with a kitchen towel. Works great; the paint is completely removed - without any chemistry!
