High heat from blow dryers tends to dry out curly hair quickly and can cause frizzing, and hair breakage. It is best to let your hair air-dry naturally. However, if you do need to dry your hair fast with a blow dryer, use the lowest heat setting and stop drying your hair just short of completely dry. Apply anti-frizz serum and moisturizing hair gel to damp hair. Curly hair needs more moisture than straight hair to stay healthy and manageable. We all need to replenish the moisture we take out of our hair with blow-drying and the use of various styling products, but curls tend to sap more moisture from hair quickly and become unruly.
Using styling products not made for curlier hair can weaken and cause damage to hair and make your tresses even more difficult to style and manage each time you try. Even products designed specifically for use on curly hair should not be overused. Curly hair needs frequent timeouts from having a lot of styling products applied to it. Most women with curly hair know how temperamental their wavy hair can be.
