How do a straightening combs work?

Straightening combs work by using heat to smooth and straighten hair. They typically feature heated plates or bristles that emit heat when plugged in, allowing users to glide the comb through their hair. As the comb passes through, the heat helps to break down the hydrogen bonds in the hair's structure, resulting in a sleeker, straighter appearance. They are often designed for ease of use, allowing for quick styling without the need for a flat iron.
