That's a common misconception a lot of people have. Since it's plastic it will melt, and it doesn't really need the haircare additives either. The conditioner is mainly used for lubrication and to keep the hair from drying out as fast. I actually make sure to clarify afterward, because I've noticed conditioner buildup can actually make the hair look less shiny. Between you and me I never liked conditioner I find it silly x3 I know it helps but I don't normally use it.
