Final answer:
To protect your scalp while using Bart's scalp salve, use only alcohol-free products, avoid harsh skin irritants, and rinse with lukewarm water.
Step-by-step explanation:
When using Bart's scalp salve, it's important to take certain precautions to ensure the health of your scalp and skin. Firstly, it is recommended to use only alcohol-free products because alcohol can cause drying and irritation to the scalp. Additionally, steer clear of harsh astringents or exfoliants, as these can further irritate the skin. During rinsing, opt for lukewarm water as extreme temperatures, whether very hot or cold, can lead to unnecessary stress on your scalp.
