From what I learned in one of my cosmetology classes, Heat does help deep conditioners penetrate the hair shaft.
However, that only works with deep conditioners, reconstructors, masks, etc.
According to the teacher (and not sure if it is correct as there are so many theories), but if you are using a regular conditioner (which was referred to as a surface conditioner), it will NOT penetrate the hair shaft, a s it's job is to close the cuticle and seal it, regardless of whether or not you use heat.
So basically what she said was, ALWAYS use a deep conditioner, reconstructor, mask, etc. with heat, rinse really well (sometimes a light shampoo once if it is heavy like affirm 5 in 1), and then ALWAYS use a surface conditioner (which would be a regular conditioner) to seal the cuticles, regardless of if you did the light shampoo or not after rinsing the dc out.
I know some may find the shampooing after a dc weird, but she stated that for fine hair, the really heavy masques will weigh the hair down, and once the ingredients have penetrated the shaft, they will not wash out...
To piggy back on the aforementioned, DC'ing with heat is not necessary after a relaxer since the cuticles are already open because of the chemical.
