Insert the barrel of the hair dryer into the end of the DevaFuser. Push the DevaFuser onto the hair dryer gently, making sure that it's firmly attached. Do not push it past the silicone band and the four Horizontal Vents above the band. These vents must remain unobstructed at all times. Turn the hair dryer on. Set the heat to low or medium temperature. Lower temperatures are gentler on curls and will reinforce all of the benefits of using the DevaFuser (more shine, less frizz, and more natural texture). Do not use more than medium heat as overheating can cause damage to both the hair dryer and the diffuser. Begin by holding the DevaFuser near the scalp to dry the roots first. Then, cradle the ends of curls in the DevaFuser and bring it up to the scalp so the hair is scrunched in the DevaFuser, and hold. To remove the DevaFuser, grasp above the band and pull gently to separate from the hair dryer.
