Hair straightening is a process used to make curly or wavy hair appear smooth and straight. This can be achieved through various methods, including using a flat iron, blow-drying with a round brush, or applying chemical treatments. Each method has its own techniques and tools, allowing individuals to choose what works best for their hair type. Chemical straightening treatments, such as keratin treatments or relaxers, alter the hair's structure to maintain straightness for an extended period. While these methods can provide long-lasting results, they may also require special care to maintain hair health and prevent damage.
