What are retail supplies intended for?

Retail supplies are intended to be sold to clients. This means that they are products or items that are meant to be purchased by customers to use at home. Option A is incorrect because it limits the use of retail supplies to only salon staff, when the main purpose is to sell them to clients. Option C is incorrect as it does not accurately describe the purpose of retail supplies, which is to be used by clients. Option D is also incorrect as it mentions testing by clients only, when in fact, retail supplies are intended to be purchased and used by clients for their personal use.
