Drink More Water. Drinking enough water is a good way to create healthier and more lustrous hair. Your body produces better hair when it’s hydrated. Most experts recommend drinking about 8-12 cups of water per day.
However, 12 cups may not be enough if you live in a climate where the atmosphere is constantly leaching water from your body. Particularly in hot and dry summers, you’ll want to up your water intake to 3-4 cups every two hours.
Skip excessive oils. Moisture comes from water, not oils. When you live in a dry environment, you need all the water you can get. Think about this: When you’re stranded in the middle of a desert, you’re reaching for the water, not the bottle of oil, right?
It’s true that oils will help to seal in moisture, but that method only works if you have a lot of water in your atmosphere and you don’t need to constantly re-hydrate your hair.
Once you add water to your hair several times per week (and you do need to do this if you reside in a dry climate), you won’t want anything blocking your way and limiting the water’s chance of reaching the hair shaft.
