Pennsylvania Barber Licensure Practice Exam

Question: 1 / 400

What ingredient in hair products is known to stiffen and hold styles?

Glycerin

Polyvinylpyrrolidone (PVP)

Polyvinylpyrrolidone (PVP) is a polymer commonly used in hair styling products for its ability to create hold and stiffness in various styles. It works by forming a film on the hair, which helps maintain the shape of the hairstyle throughout the day. PVP is particularly effective in gels, mousses, and hairsprays, where hold is a critical factor in achieving the desired look.

In contrast, glycerin is primarily a humectant that attracts moisture to the hair, silicone adds smoothness and shine without providing significant hold, and aloe vera is known for its moisturizing and soothing properties but does not provide any substantial styling hold. This differentiation in functionality underscores why PVP is recognized for its specific role in styling and maintaining hair shapes.
