Expected better results

I found this product did not do the best job covering grey hair. I wouldn't say I have a substantial amount of grey hair but it is noticeable so I was hoping this product would do the trick to cover it up. I received Dark Blonde and it was a pretty good match to my hair colour but it just didn't live up to my expectations as far as grey hair coverage. I would not purchase or recommend this product.

Umm no thanks!

Received it free..read that the product was freezing so I made sure to run straight out to my mailbox when I saw the postman coming. Was excited to try this product on the small patch of white hairs that insist on coming in along my hairline. So....1. a huge blob of messy spray came out messing up the entire bathroom and then 2. the bottle, albeit full, would not spray anymore at all. Butane problem?
Frankly I won't waste my money on a product that may or may not work properly (the spray nozzle etc) and secondly wouldn't it make way more sense to have a product that covered both grey/white hair but also rooot growth. This product specified it would only cover white hair. Not for me!
