It has a similar scent to the hims thinning-hair shampoo, in that it smells “chemically” rather than fresh or natural. That being said, I have a very receding hair line, and it is evidently obvious that it is thinning in the front. I keep my hair at a medium-short length, styling the front (when I can). It only took a small amount of the shampoo to “suds up” and evenly spread across my scalp. Following the directions, I allowed it to sit for a bit and I could feel a tingle! After only a couple uses, I could definitely notice a fuller look to my hair. I wasn’t expecting it to miraculously regrow lost hair, but I was surprised by the increase in volume it created! My only gripe with the sample was the twist lid, the full size has a flip top.
