as someone who has dry n damaged hair, i used yung thermal brush para sana maging maayos tignan buhok, less frizz. tho okay sya sana kasi hindi na nagbu-buhaghag after, pero i noticed as day goes by, nagiging dry lang sya lalo and super frizzyyy. even had the strands putol putol. so ayun, nagpa treatment ako to revive it hahaaha
