Touching and pulling your hair on a regular basis may result in considerable hair loss, and combing through it when it is damp is also a terrible idea since it can lead to thin and brittle hair. Hair styling products, such as gel, wax, and spray, can clog pores and stifle hair growth. Hair touches itself. This is because excessive rubbing and tugging at the hair shaft causes it pain which results in movement away from the head. This effect is especially true for finer hair types. The more often you pull your hair, the shorter your hair will be. Eventually, it will be too short to bother with. Hair touches something dirty. This is because dirty fingers transfer dirt to the hair shaft. Then, when you brush or rub your hair against other objects - such as a dressing table mirror - the dirt gets transferred back into your hair. This process can cause skin problems if you're not careful. It's best to wash hands regularly with soap and water after dealing with the household garbage.
