Which type of hair requires less frequent washing due to its natural oils?

Curly hair is known for having a drier texture compared to other hair types, primarily due to its natural oils having a harder time traveling down the twists and turns of the hair shaft. These natural oils, produced by the scalp, are essential for keeping hair moisturized and healthy but can take longer to distribute on curly hair. As a result, curly hair often requires less frequent washing to maintain its moisture balance, preventing it from becoming overly dry and brittle. This characteristic makes it important for individuals with curly hair to incorporate cleansing routines that do not strip away these essential oils, thus reducing the frequency of washing compared to other hair types that might need more regular cleansing.
