The 5 Biggest Hair Myths

Having long hair all of my life, and using hundreds of hair care products over the years, qualifies me (I believe) as somewhat an expert on hair care. Honestly guys n gals, 99.5% of whats been told me about hair care is "myth" or I could say bunk. Here are the top five.

Myth #1: Frequent trims make your hair grow faster.

Cutting the ends of your hair doesn't affect the follicles in your scalp, which determine how fast and how much your hair grows, says Paradi Mirmirani, MD, assistant professor of dermatology at the University of California, San Francisco. Hair grows an average of a quarter-inch every month -- whether or not you cut it. Regular trims might make your hair look a little longer, though. Getting rid of split ends reduces hair breakage, and breakage is what makes hair look thinner at the ends (and shorter), says Matt Fugate, a hairstylist at Sally Hershberger Downtown in New York City. Every eight to 12 weeks, ask your stylist to take off the minimum necessary to eliminate split ends.

Myth #2: If you always use the same shampoo, eventually it will stop working.

You don't need to practice shampoo rotation to keep your hair clean. But if you've recently started coloring your hair or increased your use of hot tools, it might be a good idea to switch to a more moisturizing shampoo, says Mirmirani. Otherwise, stick with your favorite as long as you love it.

Myth #3: A cold-water rinse makes your hair shinier.

Hairstylists love to spread this gospel. Their rationale: The icy water will make the cuticle of your hair close so it's flat (and light-reflective), not ruffled (and dull-looking). Your hair, however, contains no living cells -- it doesn't react to cold (or hot) water, says chemist Mort Westman. Use conditioners and styling products that contain silicones and oils to smooth the cuticle. And limit damage to your hair from straightening treatments, hot tools, and frequent dyeing.

Myth #4.: For healthy hair, brush 100 strokes a day.

You've probably heard that rigorous brushing will distribute the natural oils from your scalp to add shine to your hair. Or that it will stimulate blood flow to your scalp and boost hair growth. Neither is true. In fact, brushing causes friction on hair, leading to cuticle damage and breakage, which makes hair lusterless and frizzy, says Mirmirani. Brush your hair minimally (only to detangle or style), and use the right tools -- a wide-toothed comb or a paddle brush with ball-tipped, plastic bristles. Avoid boar-bristle brushes -- natural bristles aren't uniform, so they're especially harsh on your hair and scalp.
