As a Paul Mitchell product Representative may I advise you to try our SUPER SKINNY SERUM this serum not only silkens straightens and locks in moisture but reduces drying time by 30%. Also use the skinny shampoos and conditioners they help as well. For the best flat ironing section your hair. In other words do thin (and i mean thin) sections. If you bulkup your hair while flat ironing it, it will not work as well. So here you go step by step. One- take thin section and moving from scalp to end in one long smooth stroke iron your hair why using a comb behind the iron. This is so your hair doesnt burn your hand. 2- make sure your iron isnt to hot or to cool. Find a heat zone that works yet doesnt burn your hair. You may need to play around to find what setting works best. 3- if you blow dry your hair first use a paddel brush while drying. These are the big fat brushes that are flat on the backside. Try to use one with vents in the back to allow moisture and heat to get through. Also using high heat while drying will cause frizz and broken hair. A ceramic flat iron is the best. Make sure please to not leave the iron on your hair or you will have creases that might be challanging to get rid of. GOOD LUCK AND IF YOU HAVE ANY QUESTIONS YOU CAN EMAIL ME.
