If I use loreal hair color removal will it work

You'll have to give more details than that... is it a beach product that strips the hair? And what colour is your hair dyed?

Okay well I dyed my hair dark brown which is my natural hair color but when I dyed it it came out very dark likke black and I wantd to dye it orange but only the roots came outt orange

The roots only came out orange because that was your natural hair colour because part of your hair had grown a bit, when it comes to bleaching your hair to take out the colour (this is the only thing that will take any sort of colour from dyed hair)my only adive to you or anyone using a bleach is to go to your hair dressers, its really hard to do and to get an even shade all over you'd really need to go to a professional, its extremely damaging to hair and if you do it yourself you will more than likely need to put a second or third bleach in your hair and it still might not come out the way you want, so to avoid damaging your hair please go to your hairdressers, it will be safer and cost you less in the long run.

Oh and because you only just dyed it the chances are after a few washes it will become lighter, I should have mentioned that sorry
