A new study measured the anxiety that redheads feel about the dentist and concluded that they are not only nervous, but are more than twice as likely to avoid a visit altogether compared with their brunette and blonde counterparts.
Previous studies have found that people with red hair are typically more sensitive to pain and more resistant to anesthesia --- and require about 20 percent more of it to be effective.
Red hair is usually caused by a mutation in a gene called MC1R, which produces the substance that gives hair, skin and eyes their color. Some studies have indicated that this mutation may also affect the way pain is felt.
