Following manufacturer's instructions for hair products is crucial primarily to ensure safety and effectiveness. Proper usage as directed by the manufacturer can prevent adverse reactions, such as allergic responses or chemical burns, often caused by misuse or over-application.

For instance, coloring products might have specific processing times, and exceeding these can damage hair or produce uneven results.

Following salon protocols enhances consistency in service delivery but is secondary to the fundamental safety and efficacy grounded in manufacturer guidelines.
