When washing, use a shampoo, or co-wash if you have dry and damaged hair. Next, condition your hair and detangle it, removing all excess water by towel drying it (using a t-shirt is best for curls!). Before letting it air dry, add the product of your choice according to your hair. A sea salt spray adds soft beach waves on straight to wavy hair. A leave-in conditioner or smoothing cream defines waves and curls to keep away frizz. Side note: To keep hair away from the face, take some pieces and pin them back.
