What type of products must barbers use according to state regulations?

Barbers must use products that are FDA approved according to state regulations. The Food and Drug Administration (FDA) ensures that certain products meet safety and efficacy standards before they can be sold to consumers. This applies to a wide range of personal care products, including those used in barbering, such as hair color, shampoos, and conditioners. Using FDA-approved products helps to guarantee that the products have been tested for safety and will not cause harm to clients.

The other options do not meet the regulatory requirements imposed by state law. While some barbers may choose to use products with natural ingredients, not all natural products are necessarily FDA approved. Similarly, homemade products could potentially be unsafe and may not comply with health and safety regulations. Products that are widely available in stores might not adhere to the specific safety guidelines that are vital in a professional setting, making it crucial for barbers to rely solely on those that have received FDA approval.
