Hair straighteners VS Curlers: To Invest or Not to Invest???
The trick with using heat is to give your hair breaks where you can! If its an updo, then blow dry your hair, but their is no need to straighten it! Remember, If you use any hair colour, that your hair cuticle will be more prone to damage, as it has already being chemically processed.
But most importantly, do not forget to use a good HEAT PROTECTOR at the correct stage of styling - when the hair is still wet, before blow dry :)
