Working the following foods can provide you your daily dose of omega-3 fatty acids, which play a role in the health of our hair and skin like:

• fish;
• avocados; and
• nuts.

Dietitian Andrea Giancoli, MPH, RD, who serves as a spokesperson for the American Dietetic Association, tells WebMD, "Essential omega-3 fatty acids are needed to support scalp health. A deficiency can result in a dry scalp and thus hair, giving it a dull look."

Getting regular trims at the salon can also go a long way in combatting damaged hair. Having your hair cut regularly will help cut down on the number of split ends. These can cause tangles, which in turn may cause even more damage when trying to comb it out. Most stylists will tell you that since hair is not actually “alive,” there is no real way to repair it other than cutting it off and growing it back.

If you regularly heat-style your hair, it’s important to take a hot tool “detox” break every few months where you do not use heated tools on your hair for at least a week. In the meantime, use devices such as hair dryers, flat irons and curling wands on low settings. Also keep in mind that you should never, ever use a flat iron or curling wand on wet hair. This can cause even more damage.

Shampooing your hair on a daily basis can strip your hair of its natural oil and cause it to become brittle and breakable. "Don't wash your hair every day, because that can dry it out," celebrity hairstylist Chris McMillan told Allure. McMillan has worked with plenty of celebrity A-listers and is responsible for "The Rachel" cut sported by Jennifer Aniston on Friends. Only shampoo your hair three to four days a week maximum and invest in a good dry shampoo for the days in between.
