Hair Care, Makeup, and Body Care products can have a wide variety of application techniques and usage recommendations, depending on the specific product and its intended purpose. For these categories, it's best to include individual usage instructions on each product's packaging or in the product description on your website.

For Natural and Organic Samples, the application techniques and usage recommendations will generally follow the same guidelines as their conventional counterparts. It's essential to highlight the natural, organic, vegan, or cruelty-free aspects of these products in your marketing materials and product descriptions.
