In one sentence, describe what the following article is about:

In most cases, the most damaged part of the hair is the ends. By getting your hair cut every six to eight weeks, you'll removed the dry, brittle ends so your hair looks healthier overall. You don't have to cut all of the damaged sections of your hair out at once. By getting a small trim every six weeks, you'll slowly remove the dry, split ends, and over time, your hair will become healthier. Damaged hair is prone to tangles and knots, but working them out with a brush can snag your hair and cause breakage. A wide-tooth comb is a better option for damaged hair because it's gentler and less likely to pull or tug at it. Your hair is most fragile when it's wet, so it's especially important to only use a wide-tooth comb on your hair right after you've washed your hair. Damaged hair often looks dry and dull. Adding hair oil to your locks can help hydrate them and boost the shine, so your hair looks healthier. You can apply an oil all over your hair when it's wet, or just work it through the ends when your hair is dry. The best hair oils for damaged hair are argan oil, marula oil, avocado oil, and coconut oil.

Summary:
Get regular haircuts. Use a wide tooth comb. Moisturize your hair with oil.
