White vinegar is a gentle acid that neutralizes those metallic deposits. Mix one part vinegar with three parts water, pour it over your hair, and let it sit for 10 minutes. You’ll smell like a salad, but the green will retreat.
Rinse with cool water and follow up with a deep conditioner. The vinegar smell disappears once your hair dries. Seriously, it’s like magic, but with a tangy twist.
