I am basically just checking my answer because I answered plastic because it has a negative chargeThanks is advance.
Plastic is better because it is slightly negatively charged, so it won't leave your hair too static-yIts also a good choice, as aluminum will sometimes leave a rash on the scalp during winter, as it is more prone to peeling and drynessPlastic wont have this same detramental effect on the scalp.
