First time using hair dye - should I go to the salon or do it at home?

[gentlesea]

I have naturally dark hair and would like to cover up the greys that are now coming through thick and fast. I've never dyed my hair before. Would it be better to do it at a salon or is it doable at home? My only issue with the salon (apart from the cost) is that I also have thinning hair and would like to stick to more natural products. I'm assuming the salon hair dyes probably have ammonia. But I also live alone so I don't have anyone to check if I've got all the hair saturated properly.

To cover your greys I would do to at home and use a Demi permanent dye. It will give the grey but it will be slightly lighter and look like natural highlights. It will also grow out really nice with no harsh line if you can match your own colour
