Your hair goes through a whole lot. You wash it, you detangle it, you style it. Your hair is also exposed to the elements, whether it's the freezing cold or the scorching heat. Even with hair protection methods such as protective styling, which keeps the ends of the hair tucked away and off your shoulders, your ends still have to go through washing and detangling.
