Pellon is typically used in which beauty procedure?

Pellon is commonly utilized in waxing procedures primarily as a material for waxing strips. This non-woven fabric is designed to be durable and provide a firm grip on the wax, ensuring that the wax adheres well to both the skin and hair. When the strip is pulled away, it effectively removes hair from the root, making the waxing process efficient.

In contrast, the other procedures listed do not typically involve the use of Pellon. Threading relies on a twisted thread to pull hair from the follicles, shaving utilizes razors or blades, and facials focus on skin treatment without the need for a adhering strip to remove hair. Therefore, Pellon's specific role in waxing is what makes it the appropriate choice in this context.
