Straightening curly hair is often difficult, but the good news is it isn't impossible to do yourself. The process is made easier with the use of styling products and tools. To assist with detangling your curls and for additional hold, apply a product such as Kerastase Lait Nutri-Sculpt (a leave-in smoothing hair foundation) to wet hair. Before using a flat-iron make sure hair is completely dry, then separate hair into fine sections and spray in a finishing product such as Kerastase Vernis Nutri-Sculpt which helps boost shine and protects the hair from the iron's heat. Also, since it sounds like you will be heat styling your hair daily, I would recommend investing in a salon quality styling tool such as the Chi Ceramic Flat Iron. Alternatively, you may want to consult your stylist should you be interested in chemically straightening your hair permanently.*
