Ensure that your hair is fully dry before using it. Unlike flat irons with various types of plates (for dry or wet hair) this one is only applicable with dry hair. 2.) Comb your hair first before using this product. It is not designed to untangle unruly locks. If you use it to comb your hair, the heat will sort of "permanently" keep the shape of your tangled hair. 3.) Do not immediately set the temperature on high. Gradually increase it to prevent your hair from being "cooked." 4.) Do not leave the brush turned on for a long time. It doesn't have a safety feature where it automatically shuts down when it reached a certain temperature. The last we want is to have a busted piece of hardware. 5.) Ensure to cool down the brush before storing.
