oh tonic got use...think i should go buy n use... expensive...haha no choiceI'm not sure about serum. I thought serums are used on hair ends for preventing dry hair. Does it say for hair loss and growth?
My hair stylist told me to use a hair tonic which I bought from her shop. It's by Hoyu. I did notice baby hair growth after awhile and was quite happy with the product. But then again, I'm not sure if it's because of the tonic or because my body was normalizing again - which caused the baby hair to grow.
Either way, be sure not to clog up your pores with oily products. That might prevent new hair growth.
