Theres a difference between hair being heat trained and heat damaged. Heat trained hair is when your hair can withstand humidity and lasts after being straightened. The natural curl is just loosened and resists reverting back to curls when exposed to humidity. Heat damaged hair is when excessive amounts of heat have been applied to the hair and causes permanent damage to the natural curl pattern, resulting in straight, weakened, dull or dry hair. For some people who are strictly natural, meaning you dont wear it straight often, your hair will need to be heat trained. This will require a silk out from root to end but at an appropriate and safe temperature. With the right stylist, your hair can be heat trained without your curl pattern being altered and suffering heat damage.
