Final answer:
Only products with aloe vera should be used after high-frequency treatments due to their soothing and moisturizing properties. Phenol has historically been a comparison standard for disinfectants, whereas antiseptics are suitable for microbial control on living tissues.
Step-by-step explanation:
Products with aloe vera can only be safely applied to the hair or scalp after high-frequency treatments. High-frequency treatments are commonly used in the cosmetic industry and involve the use of low-current, high-frequency alternating currents delivered via a glass electrode. Because these treatments can dry the skin, it is recommended that non-irritating, hydrating products be used afterwards. Aloe vera is known for its soothing and moisturizing properties, making it an ideal candidate. In contrast, alcohol-based products might cause irritation or dryness post-treatment and should be avoided to ensure skin health.
In answering the reference questions: The effectiveness of chemical disinfectants has historically been compared to that of phenol, which was once a standard for evaluating the germicidal potency of such agents. As for the suitable substance for use on living tissues for microbial control and to prevent infection, an antiseptic is appropriate, as it is specifically designed to be non-toxic and safe for use on skin and wounds.
