During the Summer months, most people engage in long outdoor activities such as visiting beaches and amusement parks, attending barbecues, or just a fun day at the pool.  Skin and hair needs protection from the sun's harmful UV rays.  Although some UV radiation exposure is necessary for the production of Vitamin D, too much can be harmful.  Sunburn is a result of excessive exposure to UV radiation.  As a result of the overexposure, a person is more susceptible to pre-mature skin aging such as wrinkles and fine lines.  Skin cancer can also develop as a result to overexposure of UV radiation.  Not only does your skin needs protection from the sun, but also your hair.  If not properly protected, your hair becomes dry, brittle, and dull.  If your hair is color treated, the sun will change and fade the color.  Here are a few things you can do to protect your hair and skin from the sun.
