What is the most common method for achieving hair straightening?

The most common method for achieving hair straightening is through the use of flat irons. Flat irons apply direct heat to the hair strands, allowing them to become pliable and straightened effectively. This method is popular due to its accessibility and immediate results, making it a preferred choice for many individuals seeking temporary hair straightening.

Chemical relaxers, while also effective for straightening, change the hair's structure permanently and require more commitment, which makes them less commonly chosen for those looking for a quick style change. Hot combs can be effective as well, but they are less commonly used today compared to flat irons due to the advancements and convenience that flat irons provide. Hair smoothing systems often involve multiple steps and can require time and expertise, making them less widely adopted for everyday styling when quick results are desired.
