I had a stylist completely take my hair out. I had the hugest bald spot after getting a fungal scalp infection, I used about every product they had on the market to help my hair grow back. I heard about Hollywood hair bar, I decided to give it a try. I went from the regular serum to the strong serum. I totally fell in love with my new product. I have so much new growth, my hair can now be braided where it was bald and it just keep getting thicker and stronger. Love it!
