Hair is found exclusively in mammals, hair is one of the defining characteristics of the mammalian class.[1] The human body, apart from its glabrous skin, is covered in follicles which produce thick terminal and fine vellus hair. Most common interest in hair is focused on hair growth, hair types and hair care, we do't think so much about why we got hair in the first place. Many mammals have fur and other hairs that serve different functions. Hair provides thermal regulation and camouflage for many animals; for others it provides signals to other animals such as warnings, mating, or other communicative displays; and for some animals hair provides defensive functions and, rarely, even offensive protection. While humans have developed clothing and other means of keeping warm, the hair found on the head serves as primary sources of heat insulation and cooling.
Human hair may not compete with the painful spines of the porcupine, but much of the hair on the human body is suited to protect it. But we have developed into buying fur instead of appreciating our own "fur", we shave, cut, trim and wax to remove it. Are we trying to forget our origin? or the fact that we are all animals? would be rather choose to be a short haired Chihuahua or a Chinese naked cat then a lion with a full mane? im not saying that you should let everything grow, and that everyone should look like cousin IT in the Addams family, but just to except who you are with moderation;)
