Which of the following are forms of hair lighteners?

Hair lighteners are products specifically designed to lighten hair color by reducing the natural pigment in the hair. The correct answer identifies oil, powder, and cream as the forms of hair lighteners, which covers a range of applications that are commonly used in the cosmetology field.

Oil-based lighteners are often used for their conditioning properties while simultaneously lightening the hair. Powder lighteners are versatile and can be mixed with a developer to achieve varying degrees of lift, making them a favored choice in many salons. Cream lighteners provide a thicker consistency that can be easier to apply and control, especially on hair that requires precision.

Understanding these formulations is crucial for cosmetologists as each type serves different needs and hair types, allowing professionals to choose the appropriate method and product for effective and safe hair lightening.
