Your life is packed to the gills with responsibilities, and what little time you do have for yourself you don't want to waste following beauty rules that are (horrors!) plain old myths. Today on Real-Life Makeover, we're setting the record straight and debunking five tall tales from the beauty world. You might want to take notes.

Myth #1: Shaving hair makes it grow back thicker
We understand the confusion here. The hair shaft is thicker at the base, and when you shave your legs, you're cutting off the hair mid-shaft. Incoming stubble on shaved legs may feel thicker and look darker, but once it grows out it will soften.
Myth #2: Brush your hair 100 times a day
Marcia, Marcia, Marcia. You had it all wrong. Overdoing it with the hairbrush can lead to damage and cause hair to break. Instead of counting to 100, run the hairbrush through your locks just a few times to help distribute the natural oils and stimulate healthy hair follicles.

Myth #3: Polish yellows your nails
This one's actually a half-truth. Your nails are porous, so they can absorb pigment from your dark nail colors and yellow over time. Start with a clear base coat to protect nails from the pigments in those wicked reds and flirty hot pinks.
Myth #4: Hair products can fix split ends
We get split ends when the protective cuticle at the end of the hair is wrecked, causing the hair to split into two or more strands (thank your blow dryer, flat iron, and dye job for this). Products can improve the look of mangled ends by temporarily sealing the splits, but the only way to fix this problem is grab some scissors and snip away the damaged goods.
Myth #5: Drinking water keeps skin hydrated
Drinking water is essential for good health, but guzzling dozens of glasses of the stuff isn't going to fix dry, patchy skin. If your skin is parched, you need oil, not water. Stock a moisturizer formulated for your skin type in your medicine cabinet to keep skin supple.
