Doesn't hot shower always make you feel so clean and fresh? Once I get into the shower, I just don't feel like coming out. Hot showers can be so relaxing on a long day. But be careful. Really hot showers can lead to dandruff. The heat can actually suck all the moisture out of you scalp. This will cause flaking in the long run. It can be a pain to get rid of later. The heat from the shower opes the pores of your scalp. So while shampooing, it is best to keep the water warm and while conditioning turn the water little cooler. The cool water closes the pores. This also makes you feel fresh.
