Blonding hair refers to the process of lightening natural or dyed hair to achieve a blonde or lighter color. There are several methods for blonding hair, including using bleach or other lightening products that contain peroxide. The degree of lightening depends on several factors, including the starting color of the hair, the condition of the hair, and the strength of the lightening product used. It's important to note that blonding hair can be damaging to the hair, so it's essential to use proper techniques and take steps to minimize damage, such as deep conditioning treatments and regular trims to remove split ends. It's also important to follow the instructions on the lightening product carefully and to do a strand test before applying the product to the entire head to avoid unwanted results.
