Rebonding was big big BIG in Singapore about 3 years ago. Almost every girl on the street had long, poker-straight hair (which I felt was really boring)! The process itself should take about 4-5hrs, they would apply a chemical on your hair, then wash it off after about 1 hr, followed by even more chemicals and lastly manually straightening your hair using flat irons. But I must say its really worth it because you don't have to ever blow straight your hair every morning and it lasts every long! Hair becomes very manageable (sp?)!
