Relaxed hair is a hairstyle that involves chemically altering the texture of the hair to make it straighter and smoother. "Before and after relaxed hair" refers to the comparison of a person's hair before and after undergoing a hair relaxer treatment.
Hair relaxers have been used for decades, particularly by people with naturally curly or coily hair, to achieve a straighter and more manageable style. Relaxers work by breaking down the hair's natural bonds, allowing it to be reshaped and straightened. However, hair relaxers can also be damaging to the hair, as they can cause breakage, dryness, and scalp irritation.
