This is a very effective product. I already had one, and received another in error - just today. That is why it is significantly cheaper than the others being sold on the platform. I have fine hair, and a very weak hairline. The change has been significant. I have other products in this line I also use. Please contact me with any questions. This product is new, never opened. It arrived in a bubble wrap bag so the box may have a few creases, but nothing major. I will not be removing it from the box. I’ve tried other scalp serums, and what sets this one part is that it is lightweight, easy to apply, not the least bit greasy and works equally well, if not better than the others. Because I do product reviews, and have friends in cosmetics, I have many makeup brushes I am trying to get rid of. If you’d like a specific type of brush, let me know and I will include it as a gift.
