I was facing hair loss since five months so when i asked my friend she simply asked me to use viviscal for growing up my hair.but then there are a lot of the my other friends who have told me not to use viviscal as it incurs a lot of side effects.so before going to purchase it i would want to know what are the side effects one has after applying viviscal for hair growth? will the side effect be such that my hair will not be growing again?is viviscal scientifically researched or proven so that i can use it without any worries?since i need my hair to grow fast i want to buy Viviscal but if there are a lot of side effects associated with Viviscal then i will try some other alternative to regrow my thinning hairline?
