Is wax in shampoo good or bad for your hair?

Bad

Waxes are typically used in hair styling products to provide hold and definition. However, when used in shampoo, waxes can leave behind a heavy residue that can weigh hair down and make it look greasy. Waxes can also interfere with the scalp's natural sebum production, leading to dryness and itching. For these reasons, it is generally not recommended to use shampoo that contains wax.
