How often does mel need to reaply his purple dye? ——— Hm... I'd say every 2 months? I don't keep track of how often I reapply my hair dye, but I usually do it when I decide that it's time to cut my hair as well. Once my "micro bangs" start tickling my "eyebrows", I already know I'm gonna spend the night in the bathroom, sigh (-ω-`)
