@ilesformula_hair: The step everyone rushes: the rinse. Rinse the Iles Formula Shampoo well, its sulfate free and all sulfates free shampoos need a good rinse. No rush . Then the Iles Formula Conditioner is unique in its function, that once it’s rinsed, it leaves no residue what so ever. Hence the key — be sure the shampoo is out before conditioner goes on. “When the hair is truly healthy, it almost styles itself.” —Wendy Iles, founder of Iles Formula Shop now.
