Some people have braid extensions put in because they like the way the braids look, while others have the braids put in hoping to grow their natural hair longer. Regardless of what you're hoping to achieve, braid extensions rob your strands of moisture. To combat this, use castor oil to help keep your scalp moisturized and your hair healthy and strong.

Braid extensions are commonly seen in African-American hair. When braid extensions are put in your hair, your scalp can get dry and itchy over time. Dandruff is not uncommon in people with braid extensions. To avoid the white flakes, moisturize your scalp with castor oil at least three times a week. Wet your fingertips with the oil. Part your braids and rub the oil on your scalp. For a pleasant scent, add three drops of your favorite essential oil to the castor oil.

If your scalp feels tight and is severely dry, an overnight conditioning treatment may help. Saturate your scalp with a generous amount of castor oil before going to bed. Wrap your head with a towel overnight, or wear a plastic cap. In the morning, remove the cap and wash your hair with a mild shampoo and conditioner that is made for your hair type. Once dry, lightly apply some of the oil to your scalp and braids to keep them moisturized and frizz-free.

Another way to apply castor oil to your scalp is by adding it to your regular hair conditioner. Mix 1 teaspoon of castor oil to the amount of conditioner you normally apply to your hair. After washing your hair, use the mixture to give yourself a deep-conditioning treatment. Massage it into your scalp and leave it on for at least three minutes. Rinse you scalp with warm water.

Besides castor oil, there are many other oils you can use to condition your scalp and braids. Coconut oil, for instance, is known to soften your hair and keep your scalp conditioned. It can be used both before washing your hair and afterward. Other oils known for their moisturizing benefits include jojoba oil, olive oil and sweet almond oil. If you find castor oil too thick and heavy for your hair, thin it by adding an equal amount of any other vegetable oil to it.
