or aluminum or anything else on your hair when you dye it?
I don't think it does anything.but then again, drinking lots of water is supposed to help with acne and ice is the same thing, so maybe it could help a tiny bit? It definitely won't make it worse though
Eh.Nothing Foils are just used in Highlights to seperate colored hair from non colored hair, and the plastic bag(I'm assuming is the plastic shower cap thing.)is used when you go under the dryer to stop the color from drying out.
