Which lasts longer: hair smoothening or hair straightening?
Can you explain the difference between hair smoothening and hair straightening?
Hair smoothening involves using chemicals to relax the hair and make it easier to manage. It does not make the hair poker straight but rather makes it smoother and reduces frizz. Hair straightening, on the other hand, involves using heat to straighten the hair and it may make the hair look flat and lifeless.
