Organic virgin coconut oil makes a nourishing deep conditioner for your hair. Its fatty acids penetrate the shafts of your hair and provide antioxidants to protect against free radicals. This is quite different from the processed vegetable oils in many conditioners which create free radicals instead.
To deep condition your hair, leave a teaspoon to two teaspoons on your damp hair for a few hours or even overnight. You can do this conditioning as often as once a week.
Coconut oil as a scalp massage may relieve dandruff and other scalp conditions because of its antifungal properties.
"Because coconut oil readily absorbs into the skin, when it's applied to your scalp, it also absorbs into your blood for a quick dose of a powerful natural antifungal, antiviral and antibacterial - and one that germs and bugs don't build immunity against." For this reason, you might want to use coconut oil as a body wash, to enhance immunity rather than compromising it with commercial chemical-based body washes.
