A hot oil treatment is the process of adding warm oil to the hair and scalp. The purpose of the treatment is to ensure that the moisture from water is retained as well as to soothe dry scalp. It is very useful year round. The treatment can be done wet or dry but is more effective when done wet. Water is one of the best moisturizer and this process helps to utilize the moisture from the water naturally.
Tea Tree Oil, Olive Oil, Castor Oil, Sunflower Oil, Vitamin E, Jojoba Oil and Many Other Oils.
You can use either one of those oils and there are others not listed. Keep in mind that the hot oil treatment requires about an ounce of oil depending on the length of your hair which is a good amount of oil per treatment. You don't need to completely saturate your head with oil. This will do more harm than good because the oil is not a source of moisture but a moisture retaining tool. I personally use olive oil because its one of the least expensive natural oils. You can use it as a carrier oil for essential oils such as peppermint, lemon grass, lavendar and etc for their fragrances or beneficiary properties.
How its done?
Prepare the water bath for the oil.
Boil about a cup of water. Pour about an ounce of oil in a smaller bowl, cup, or plastic bottle. After the water has started boiling remove it from the heat. Place the oil container in the water container for about 2-5 mins or until warm. Add the warm oil to wet clean scalp and hair. Rub in and comb through with a wide tooth comb. Cover head with Saran Wrap or plastic shower cap without heat for about 20 to 30 mins . If you sit under a hood dryer 5 to 15 mins while head is still covered. Rinse out excessive oil with warm water. If you wash hair with shampoo or shampoo alternatives you will negate the hot oil treatment.
How often is it done?
It really depends on your hair type. If you have dry hair once a week. Fine hair once every two weeks or once a month. Hot oil treatments in excess will not harm your hair if done correctly.
