Would it be ok to put highlights in my already semi-permanent dyed hair? if not, why, can i do this

I really want to add highlights to my hair. I had previously dyed my natural, sandy brown, hair color to a black/blue color. my hair has faded quite a bit and is about 2 to 3 shades away from my natural color. should I just wait until all of the color is gone or could i still highlight my hair myself right now? I'm looking to highlight it a honey blonde color and I have african american hair. My hair is already in good condition with no breakage that I can see. I'm really trying to avoid a hair salon, thanks!!

If you can place the highlights on yourself with bleach mixed with 20 volume developer wrapped in foils then process with heat to the level of lightness you want then you wash out the bleach and you will probably want to tone it down with a semi permanent honey blond color. If you think you are able to do all that then go ahead and give it a try, I know I would want someone else to place the foils on for me and I'm a professional! Good Luck!!!

Highlights are a lot harder than dying your whole head a color. Try using the dyes that wash out before committing to a dyi highlight job. That way you can see how it would look before you go permanent.

You can lighten but you must use a bleach or other color remover. The choices in a public beauty supply are not the best. Hair color will not lift out hair color with the results you expect if at all. Here are the problems you are going to be left with highlights that have two different levels and tones. You would have to mix two different strength lighteners and apply to the appropriate areas and then adjust with toner. This is not something you should be attempting. Find a salon in your budget that works with African American hair. You sound like you have nice hair- keep it that way!

The thing about at-home color is that it's really unpredictable. There's a reason salons charge more than $10 for a dye job, and it's not just because the salon costs more to run. I'd use a color-stripping shampoo (clarifying shampoo) until the color fades a bit more and then maybe try the home highlights if you're not concerned with possible consequences. It could turn out, but you never really know. Highlighting is bleaching so expect your hair to be super damaged and hard to comb.. been there, done that.
