Can I dye over dyed hair instead of just doing the regrowth?

I dyed my hair 6 weeks ago just to dye some grey strands (very easy %26amp; just had to massage through). Now I need to just do some regrowth touchup but can I just dye my all hair again? What would happen if I just reapply dark brown hair dye over my previous dark brown hairdye done 6 weeks ago?

Thanks in advance!

Yes, you can. It will be whatever color the dye is. You shouldn't be able to tell a difference between new growth and other hair.

Nothing really bad will happen. If anything you may have had some fading with your previous color. Yo can do the touch up and process for the recommended time (per manufacterer's instructions) and pull the color through to the rest of your hair for the last 7-10 minutes or so, just to refresh your previous color.

well it depends on how ur hair does with the chemicals, it could cause splitt ends, basically dry out your hair, but since my hair has a lot of oils in it, i can dye it a lot and its fine, but i think it depends on how harsh the chemicals are that are in the hair dye, bleach is really harsh, and i dont know if grays are any different, b/c arent gray hairs really wiry? so i think u can try it, but if it gets dried out, u can do a hot oil treatment or leave-in conditioners. i hope i helped u

dyed hair is hard to dye again. the pores in your hair just soaked in the dye and it won't be likely to absorb more of it. trust me; i've tried to dye over dyed hair and it just washes out. why don't you just touch up the roots? if you want to dye your whole head over again, i'd wait at least another month before your hair is ready to absorb more chemicals. if you do it now, most likely you'll just damage your hair even more without gaining much more color.

you should mainly concintrate on the new growth. but if you want to also run the color through the ends (preferibley at the end duration of the time it takes to process) then thats ok. i say this because if you leave it on the whole time every time then your just over processing your hair more than needed. but for refeshing your ends thats ok,. i would delute it with water for the ends though.
