hi i am A 23 yr old girl and had my hair treated chemically treated many times. my hair have been chemically straightened thrice and coloured twice. i was living in UK for the past one and a half year, and due to cold and dry/humid weather there i started having a lot of hairfall. this might also be because i was not able to get post straighting spa after going there. my hair have become thin and dry at the ends and break easily . what products should i use to improve their condition
