Following the manufacturer's instructions is fundamental when using chemical treatments because these guidelines are developed based on thorough research and testing to ensure safety and effectiveness. Each product has specific formulations and recommended application processes that are crucial to achieving the desired results while minimizing risks such as chemical burns, hair damage, or adverse reactions.

Understanding the manufacturer's instructions helps a barber understand the correct dosage, timing, and application methods required for the treatment. This ensures that the chemicals perform as intended while also safeguarding both the client’s hair and skin.

On the other hand, using higher doses could lead to unintended damage, mixing products without professional guidance can result in harmful reactions, and applying treatments only on dry hair isn’t suitable for all types of chemical processes. Each of these alternatives disregards the carefully calibrated processes established by the manufacturers, which can compromise both safety and effectiveness.
