Even if it isn't bright or overly sunny out, wear at least SPF 15 when you go out -- either sunscreen or foundation with sunscreen in it. UVA and UVB rays can still hit you, even on cloudy days.

Before you shave your legs, use an exfoliating scrub to soften the skin -- and remember to rinse it off first. Your legs will feel smoother, and your shave will last longer.

Don't wash your hair immediately before applying color. Your hair needs that natural oil to protect your scalp from the dye, and it also helps the hair shaft absorb the color more easily.

If it's hot and humid outside, make sure to use loose powder when you put on your makeup. Apply with a large cosmetics brush. This will set your foundation and make it less likely to run in the heat.
