Initially I was wary of using this as the product is quite cheap, and I was afraid it might be of inferior quality. I have a sensitive scalp and spiderwebby fine hair, and was afraid it would make my hair fall. However fears were unfounded and this product is great. It has a faint onion odour, but this is intermingled with the scent of essential oil, so it's not unpleasant. I also like that it doesn't make my hair limp and flat after washing as many oil-based products do. Best of all, I can see and feel stubble on my scalp where hopefully thicker hair is emerging!
