This set of combs is made of sturdy carbon fiber material, lighter and stronger than plastic. They can be used when styling with heat up to 250C without melting and help eliminate flyaways for static free results. Style hair starting at the ends and move up to the roots, using the end tail comb to part the hair. Follow with a flat iron or blow dryer for a sleek style. Use with the Thermal Shield Heat Protectant to protect hair against heat damage.
