hair color fillers explained- going darker to avoid green hair | 2024

what hair color fillers are & how to use them.

*key points:
•a color filler is needed if you are going 3 or more levels darker

•a color filler adds back in missing pigment to the hair (usually the pigment that is lost when bleaching)

•you have to have all three primaries present when coloring hair (red, blue, and yellow)

•yellow = blondes, red= medium browns, blue= darker colors/ blacks

•if you color your hair darker- going from blonde (YELLOW) to black (BLUE) you will be missing the middle primary (RED). You would use a red filler to avoid getting the opposite color of red-green.

•to fill hair:

color the hair red (I used 7RR demi permanent color + 10 volume) let it process, shampoo and condition, blow dry, or towel dry.

apply your desired color over the red (I used 4NN liquid permanent color + 10 volume), let it process, shampoo and condition.

if your hair still has too much red in it, you can apply the desired color again- let it process, shampoo and condition.

You explain this better than anyone — ( I was raised in a beauty shop) I’ve done my own hair for years-) thank you - -

[wendyd]

I have no desire to go to darker hair. I just love watching your videos. You explain things so well 🩷

I went to a professional stylist to color my blonde hair a dark chocolate brown. While sitting in the chair as color processed the dye started to run down my face. 3 days and $175 later I started to see blonde patches showing through the dark brown... so I stripped the dark brown off and dyed it back to medium blonde. I knew about the hair filler but I also assumed since she was a professional that she did too! When I dye my hair at home it never runs!! I'm finished with salons and throwing my money down the drain!! 😢

Oh my gawd thank you gf! I’ve watched so many videos on this topic that has the hairdresser just squirting the red and the brown colors into the same bowl and brushing it on. Thanks for letting us know that this is a multiple step process! Wish me luck! ❤😂

[lanaowens]

Best filler explanation yet. Fantastic - Thank you!

I've watched many videos on this topic but this is the first time the lightbulb came on for me. Thanks for explaining this with visuals. Great job!!!

This goes right over my head and why I rarely color my hair.

I’ve been doing here for 36 years and I agree with you for some reason. I am so stumped. I am going to send you three pictures. The first two pictures are what it is now exactly the third picture is the desired color. I was going to fill it with an endG, but I think I need to add some red to it for some reason I think I am thinking too much and how to do this

[jenna_baker]

I know you can't see my hair to gauge it, but I didn't know about fillers until after it was too late with a color depositing conditioner from a bleached blonde (maybe level 9) and I put darkest espresso brown over it and turned it green like you said. can I put dark red color conditioner over this and let it process alone, or should I mix the dark brown and dark red together now that it's after the fact? I would do demi permanent like you said, but I really want the color to wash out without remover quickly by spring and demi's kind of scare me lol

[MyaBibra]

This is such a good video! I've been looking for a good explanation for years - I dye my hair, and the highlights went slightly green. I'm now confident on how to fix it. Thank you x

[doribrown]

You are an amazing teacher - such clarity!

[Verbatim.]

Can you please do a video on hair gloss vs glaze pretty please 🙏

[scottrachell]

Thank you for this....I'm currently not living in the States and the salons where I am don't tone highlights and they use 'natural' dyes when doing hair color. After my last disaster of getting my greys blended (and terrible highlights), I've asked multiple times to get my hair taken back to dark brown and each salon told me it 'wasn't possible' and my hair would either be orange or green. Now I know why - they either don't know about or don't do fillers. I plan to do this by myself at home and your video helped explain the process. Thank you!
