You have hair covering your entire body—for several purposes. Not only does it help keep dirt and debris away from your skin, but hair also helps combat water loss and keeps you insulated, protecting you against extremes of hot and cold. The hair on your body plays a sensory role as well. The movement that occurs with the hair on top of your skin helps to detect the slightest change in temperature and touch.
If you think about it, hair protects you against all kinds of daily offenders you probably never consider.
- The hair on your head protects your scalp against the harsh burning rays of the sun.
- Hair, which is made from keratin (a durable protein that also makes up the outer skin and nails), has a high sulfur content, giving it heat-retaining properties.
- Did you know that up to 60% of heat loss comes from your head? So hair can keep you warmer on a cold winter’s day.
- Eyebrows can help keep sweat from reaching your eyes, and eyelashes keep dirt, debris, and foreign objects away from the delicate eye tissue.
- Hair in your ears also keeps foreign offenders such as dirt and bugs away from the inner ear, due in part to the waxy substance this hair is coated with.
- Finally, nose hair filters out all kinds of debris from the air like dirt, pollen, and germs.
There are a few things I want to define before going further in order to bypass any confusion about the words being used.
- Depilation removes part of the hair from the surface of the skin. Depilation methods include shaving, trimming, and depilatory creams. Depilation has the shortest regrowth time; usually within a day or two you will start seeing hair reappearing on the surface of your skin.
- Epilation takes the entire hair or root from the hair follicle. Techniques for epilation include tweezing, waxing, sugaring, threading, and rotary epilators. Hair reappearance after epilation takes anywhere from several days to several weeks. Both depilation and epilation are considered temporary ways to remove unwanted hair.
- Permanent (or close to permanent) methods I will discuss are electrolysis and laser hair removal. The recurrence of hair growth with these more permanent procedures varies a great deal. It can take up to a year of treatments to keep the hair from returning, and even then there are no guarantees. More often than not, however, these techniques can permanently get rid of unwanted hair.
Finally, when I mention the upper lip or upper lip area, I am referring to the area where a man’s moustache would grow, the skin and hair above the upper lip. Using the term upper lip just requires fewer words, but I am not referring to the actual upper lip of the mouth. For instance, a woman getting a lip wax is obviously not waxing the actual lip, but the hair above it.
