Using a barrier cream or petroleum jelly is essential for protecting the skin from chemical burns during hair coloring. These products create a protective layer that prevents the harsh chemicals present in hair dye from coming into direct contact with the skin. This is particularly important around sensitive areas such as the hairline and ears, where irritation can easily occur.

Moisturizers, hydrating serums, and baby oil, while beneficial for skin care, do not provide the same protective barrier properties that a specialized barrier cream or petroleum jelly offers. Moisturizers and hydrating serums are designed to hydrate and nourish the skin but may not effectively prevent the penetration of chemicals. Baby oil can provide some level of protection; however, it is not specifically formulated for this purpose and may not adhere as effectively to the skin as a barrier cream would. Thus, for optimal protection during the coloring process, a barrier cream or petroleum jelly is the most appropriate choice.
