'cuz I left conditioner in??

Hi,Last week a couple people gave me some very good advice to rinse with cool water. The first time I tried this my hair had less tangles and felt softer then before.The next time I washed my hair it was time for my weekly conditioning (Pears daily care conditioner). The week before my hair turned out ok... I hadn't started the cool rinsing yet though. This was the first time I used the cool rinse the same day that I conditioned my hair.But for some reason I decided to leave the conditioner in for about 2 minutes before rinsing it out. (only 2 or 3 weeks ago I was using Pantene 2 in 1 shampoo and conditioner) After I rinsed out the conditioner (which was applied only from the ears down), then I rinsed with cool water.My hair really poofed out!! I could not believe the volume I got!! But.... it came with a bit of dryness too. An inch or two near the forehead was peeling/flaking... and even my forehead itself was really flaking. When I rubbed my forehead with my finger (not the nail) it looked like it was snowing!!What do you think? Was it because I left the conditioner in? Is this good or bad? Because of this I skipped 2 days of washing my hair to let the oil come back a bit. This is the first time I was able to go that long without washing my hair without it getting too oily. (that's why I don't know if this is good or bad)I loved the volume... but not the flakes.What is the cool rinse for again? Did the combination of the cool rinse and the conditioner have anything to do with it?From the ears down I still have a perm. What is best for my unpermed hair and what is best for my permed hair?P.S. I LOVE this board!!
