Dying over black dyed hair with blue hair dye..?

Question

I dyed my hair black two days ago. I want to dye over it again with blue so it'll be slightly bluish. Will there be any bad color effects?

Answer 1

If subtle is what you want then no there are no bad effects. It will end up as a blue black but will not be super noticeable in certain lighting. If your looking to get it a dark blue where you can tell the color you would have to lighten it a bit with blonde box dye or bleach. Either way you have to leave the color on for awhile in order to get the bluish tint you want. I have to leave on my dye for an hour which is safe because box color and direct dyes have short processing times and typically stop processing after 30 minutes. I would also recommend putting a shower cap over your hair while you wait to help the color seep into the cuticle. If whatever dye you use leaves your hair dry feeling use a deep conditioner or you favorite conditioner and leave it on for 30 minutes-1 hour.

Answer 2

It would be hard to see. For the best effect use bleach over the black to make the color more bold. If you do not want that wait a week for the black to lighten up a little then apply the blue dye. Mix in a little peroxide with the die for best effect. Good luck
