I could be completely wrong on this....but I believe cooler water helps in two ways. First is that hot water leads to more of a dry scalp after your shower. So you can wash and scrub hard with hot water, but once you're out of shower the skin on your scalp is drying and cracking because of the heat---causing more dandruff after you've already scrubbed the previous off. More important though, hot water removes more oil from your hair and scalp than cooler water, and these natural oils (on top of other things) can help prevent dandruff.Cant you just take a hot shower like usual and then hose your hair with colder water and wash it out afterward?
