Curl blow drying is a hairstyling technique that uses a blow dryer and a round brush to create curls or waves in the hair. It is a popular styling method for people with all hair types, but it is especially effective for people with fine or thin hair, as it can help to add volume and body.
There are many different ways to curl blow dry hair, but the most common method is to start by blow drying the hair until it is about 80% dry. Then, take a section of hair and wrap it around the barrel of the round brush. Hold the blow dryer pointed at the hair and brush it down the length of the hair, from roots to tips. Repeat this process for each section of hair.
