I went to a salon for threading my eyebrows, but the attendant there, just spoiled them by threading them too far, and now my eyebrows look too thin on my face. I have a round face, and I am in 7th grade, this new eyebrow shape has pestered me a lot, and presently I am using eyebrow pencil for them. I am also using olive oil with a hope that it might grow them back, but nothing seems to work for my brows! I have always had bushy eyebrows, as I have liked them that ways on my face, but thin eyebrows are not just of my type! I would like to know from some skin expert whether biotin supplement might work to grow my eyebrows back, as it helps for hair growth! Can you guys please help me with some suitable assistance?
