Which oil is recommended to be avoided for pre-waxing skin preparation?

Mineral oil is recommended to be avoided for pre-waxing skin preparation because it acts as a barrier on the skin. This can prevent the wax from adhering properly to the hair, making the waxing process less effective. For optimal results, the skin should be clean and free of oils that can inhibit the wax's grip on the hair. Unlike mineral oil, oils such as olive oil, jojoba oil, and coconut oil can have beneficial properties, like moisturizing the skin without significantly interfering with the waxing process, although they may also be avoided to some extent depending on individual techniques and skin types.
