Summarize the following:
Keep your hair moisturized throughout the week. Try to moisturize your hair every 2 or 3 days or as soon as you notice your hair drying and frizzing. For a quick moisturizing routine, just remove your hair from the twists and spritz it with water. Rub through a leave-in conditioner and brush your hair. Rub through olive oil for extra moisturizer.  You can leave your hair down or re-twist it into a protective style. For the most moisture, do a deep moisturizing treatment once a week. Dry hair is often caused by removing the natural oils from your hair. If you currently wash your hair every day, start waiting a day or two in between shampoos. This will give your hair a chance to stay moisturized from its own oils. When you do shampoo, choose a gentle shampoo that contains aloe vera or apricot kernel oil. These ingredients can help your hair stay moisturized. Your hair may dry out more quickly if it's exposed to wind, sun, chlorine, dry air, or saltwater. If you'll be encountering any of these, cover your hair with a scarf or hat. You should also increase your conditioning before and after coming into contact with these damaging elements. If you'll be in the sun, you can also spray your hair with a protective spray that blocks UV rays. Even the most moisturized hair can dry out if you use too many drying treatments. Coloring your hair or getting perms, relaxers, and chemical smothers can all dry out your hair. Consider doing these rarely to avoid drying out your hair. If you do color or highlight your hair, choose chemical-free or ammonia-free treatments since they're less damaging to your hair.

Summary:
Moisturize your hair several times a week. Avoid shampooing your hair too often. Protect your hair. Cut out the chemicals.
