The technique of using a flat lancet to open pustules is typically employed for which hair type?

The technique of using a flat lancet to open pustules is particularly effective for ingrown hair. Ingrown hairs occur when a hair curls back or grows sideways into the skin, often leading to the formation of a pustule or infection at the site. By using a flat lancet, a technician can safely open the pustule, allowing for drainage of pus and reducing the risk of further infection or irritation.

This method is crucial because it helps alleviate the pressure and discomfort associated with ingrown hairs. Furthermore, it allows for careful extraction of the hair without causing more trauma to the surrounding tissue. Employing a flat lancet in this context is a specialized approach that ensures both effective treatment and patient comfort.
