Truth:
Haircare manufacturers keep this widely held belief alive. But, except in rare cases, the hair that grows out of your head is healthy even if it’s not as shiny as you’d like. There’s no shine test to determine the overall health of the hair. Straight hair is shinier than curly hair.

Myth: Daily washing damages hair.

Truth:
If you use a mild shampoo, it’s OK to wash hair daily. Opt for opaque, creamy shampoos over clear formulations.

Myth: Brush your hair up to 100 times a day to make it shine.

Truth:
According to the old wives’ tale, you need to brush to disperse the natural oils in your hair. We now know that this happens whether you brush or not. The danger of this old-fashioned tip is that over vigorous treatment can tear hair shafts and damage roots.

Myth: Daily blow-drying thins hair.

Truth:
Trichologists say that daily blow-drying can dehydrate hair and make it frizzy if you don’t use a heat protection styling product. Thinning hair, though, is mainly caused by hormones, age and heredity.

Myth: Vitamin supplements will make hair grow faster.

Truth:
Vitamins B6 and B12 are necessary for healthy hair. Most people get enough of these by eating a balanced diet or taking a daily multivitamin. Taking mega amounts won’t make hair any healthier than it is naturally. Supplements that claim to increase hair growth and strength don’t do much either, say dermatologists
