Absolutely L O V E this product.

Unfortunately, it does not contain enough product to complete a full head of hair. I end up using 1 1/2 bottles. Since this product is quite expensive compared to many other brands, its cost becomes quite high.
However, I still use it since the color is perfect for me. On the down side, It does not cover grey very well. You must leave in much longer than prescribed.

Loreal preference is my go to hair colour. It covers stubborn grey hair, is practically odorless and is very easy to apply. I think all hair colours would be better if they contained guidance on how to safely discard leftover colour as i find dumping it in the sink might be harmful to our water system.

This is a cool idea because this bottle is already mixed for you. You shake the can and apply as much as needed. Then, you can just store the bottle away until your next color 6-8 weeks later. It is a mousse application so I found it didn't soak into my hair properly and I ended up using the entire bottle. It is around $15 which would be great if you got your 2 applications from it. The end color result is quite nice. it is rich and shiny. it does cover grey well also. I just didn't like the whole system.

Pricier than old style mixing packs of preference..but its lot more easier

I loved how easy it was!!!!! It's like an aerosol can just shake, press and GO!!! Also I have average length hair and I still have enough for at least and this is the first reusable hair colour I've ever seen!!!!
