The latest on the fashion scene is to have long smooth straight hair. While there are commercial hair straighteners like chemicals and flat irons to smooth out curly hair, they do have their side effects and lead to hair damage. Here's how you can make curly hair long naturally using products like coconut milk, lemon juice, honey, milk, olive oil, coconut oil and egg. Apply a mixture of coconut oil and lemon juice which helps smooth out curly hair, and cover it with a hot towel. Wash and see the curls fade away. Hot oil treatment, milk and honey mixture, egg and olive oil mixture when applied regularly over the head and washed will help smooth out curls. They are great conditioners.
