In order to create sexy sleek straight hair, you will need the following: clips/hair ties, heat protective spray, shine spray, a flat iron, and wax or hair balm. Spray the hair with heat protecting spray and shine spray. Don't be stingy with the spray. Coat the hair well. Brush the hair thoroughly. Section the hair and clasp it with hair ties. Begin straightening the hair one small section at a time. Continue working your way through your hair until it has all been straightened. Finish the look by adding some hair balm or wax to your hair. Dab a small amount onto your fingers and work it into your hair. This will give it texture.
