i have very wavy hair that when i comb do not look like the way i want them to look like and this really annoys me.i try to straighten them so much ,but they always assume their earlier shape as if all the hard work i put in and straightening them with an iron has gone to waste. some days it works out for me but only for some time like three to four hours,which is not enough for me.Then my friend told me about Thermal Reconditioning of my hair.how long will Thermal Reconditioning help my hair to straight out?will it spoil my hair texture?
