What is the most common method of hair straightening?

Chemical straightening is widely regarded as the most common method of hair straightening. This process involves the use of specific chemical solutions that alter the hair's structure, making it straighter for a longer duration compared to other methods. The appeal of chemical straightening lies in its long-lasting results, which can often last for several months, depending on the individual's hair type and maintenance routine.

While temporary straightening methods like styling creams or sprays offer quick fixes for a sleek look, they typically do not provide the same longevity or effectiveness as chemical treatments. Heat styling, such as using flat irons or blow dryers, can achieve straight hair but requires regular application and can lead to heat damage. Natural straightening methods may include techniques that leverage humidity and the natural texture of hair but do not provide the level of straightening that chemical processes can. Therefore, in terms of both effectiveness and longevity, chemical straightening stands out as the preferred choice in professional settings, making it the most common method for those seeking straight hair.
