hello ladies, i'm a chennai native who has been living in the USA for the past few years. I plan to visit chennai in july and need your help with my hair issue. I have natural wavy hair which I blow dry and straighten here in the states, however the last time I was in india my hair would not stay straight even if i straighten it. I assume that the issue is with the moisture conditions in chennai. Please note that I do my hair at home and not in a parlour. Please let me know what kind of serum/lotions would help me with my hair in chennai. Thanks in advance.
