Does anyone get the feeling that the heat makes the conditioner evaporate, or maybe its just penetrating, sometimes I wonder.

I don't think it evaporates away since the plastic cap traps it. If it does vaporize, it condenses right back down onto your hair which is all ready to receive it. According to Cathy Howse (and I like her logic) the heat allows your hair strands to expand so that the good stuff is absorbed right into the core where it's needed most and where it can make a difference. Maybe it's all in the mind but I do think my hair feels better when I deep condition with heat.
