So i haven't had my hair trimmed for about a year now, and it's the healthiest, softest, and shiniest it's ever been. All i do is once a week, put coconut oil on my hair, and leave it in for about 30 minutes. I clip my hair up and wear a shower cap to keep the coconut oil from getting all over my clothes, then i rinse it out with warm water, then wash my hair with shampoo and conditioner like normal. Then I rinse my hair with cold water because cold water makes my hair shinier. Coconut oil is so great for a hair mask it doesn't get rid of split ends, but it does prevent them and makes your hair way healthier overall.
