What Do We Need to Know About Hair Straightening?

Hair straightening is a common procedure that has evolved over time from the use of permanent relaxers to formaldehyde-free methods like hair Botox, which is currently popular. These modern methods improve hair manageability, increase hair strength, and reduce frizz without causing significant chemical damage, thus maintaining the hair's natural waves for a more natural look. Temporary methods such as blow drying and ironing are also used for easy hair management.
