Heat Damaged Hair: How to Tell, What Lasts and How to Fix It
Hot tools change hair a little more with every session, and the hair cannot undo it. If yours feels best the day you straighten it and worst after the next wash, that pattern often points to heat damage. You can find where it sits, stop adding to it and trim it away as new hair grows in.
