As a stylist, cosmetologist, or extensionist, you use different types of hair extension techniques, such as sew-in weaves, to help customers achieve their desired appearance. Hair extension is an easy way to add length and volume to shorter hair, create beautiful styles for special occasions, help people who are suffering from hair loss, and satisfy those who are just looking for a change. In this role, your duties and responsibilities include helping clients select extensions that are appropriate for their goals, installing the extensions using glue or other methods, cutting and styling the extensions so they blend with the customer’s natural hair, and handling removals when your client’s hair grows out.
