Central heating and sun exposure can dry the hair and make it look frizzy. However, there is an easy way to reduce frizz by applying a moisturising coconut oil hair mask. Gather three tablespoons of coconut oil and place into a saucepan. Melt the oil under a low heat. Add one egg and stir until the ingredients have melted to a thicker consistency. Ensure that the mixture is warm and not hot, as you do not want to burn the scalp. Apply it to the tips of the hair and continue until the mixture has covered the entire hair area. Add a plastic bag, which will steam the hair slightly, and wash out after thirty minutes for shiny frizz-free locks.
