I purchased a small pack as I was skeptical that this product would work and after 15 years of having thin hair and trying everything, what would work. Before my very eyes the thin part at the front of my hair changed to thick hair in know time. This product really does work and I have since purchased more! I am more confident now in going places and even to work as I sit under a fluro light, even thin haired persons nightmare! Thank you, you have changed my life.
