Straight hair products consist of any cosmetic preparations designed to make curly or textured hair become straight or relaxed. For many people with naturally curly or coily hair, these products offer a convenient way to create a different look or style.
The use of hair relaxers has a long history and has been used in various cultures. Chemical straighteners, which permanently alter the hair's structure, were introduced in the mid-20th century. These products have gained popularity due to their ability to provide long-lasting results and ease of use.
