[0002] Hair care devices include combs, hair dryers, hair conditioners, and scalp therapy devices. Combing hair is an essential part of daily grooming for beautiful hair. Combing removes debris and dirt from the head and hair, provides moderate stimulation to the scalp, promotes blood circulation, and leaves hair soft and shiny. Combs and hair dryers are both common household items. Combs are primarily used for combing hair, beards, and animal hair, while hair dryers are primarily used for drying hair or beards. After washing their hair, users typically use a comb and a hair dryer to comb and dry their hair separately. Using a comb and a hair dryer separately is cumbersome and inconvenient, and provides relatively low comfort. Combs are an improvement on hair dryers. These hair care devices not only dry hair but also comb and massage it. Different hair dryer barrels can be replaced to suit different hair styles. Therefore, combs have gradually become a must-have for hairdressing.
