Would permanent dye cover my faded out pink? (+ bonus henna question)

[Strawonaberry]

Hi :) so, I dyed my hair pink last year, and haven't touched up the roots since. here's a recent pic (https://imgur.com/U3Q97oY) (sorry for the messiness ^^"). I reapply the pink now and then, and it can get a little more faded than in the pic, but it's kind of impregnated into the hair so it never goes back to yellow. (The bleached hair underneath was very light but yellow-ish rather than toned).
You can see on the picture, but I'd say my hair is a very ashy blondette or light brown (with 0 red to it).

I'm getting kinda tired of the color and was wondering if I could cover it up with something close to my natural color. I was thinking some gentle brand of permanent dye, like elgon dolce or argan oil (I haven't done the full research though, but you can make recommendations). Do you think it can be done without bleaching over the pink? It's still in pretty good condition and I wouldn't wanna mess it up too much.

My bonus henna question is: If I went ahead with this, and then wanted to do a henna gloss all over (Just a daydream I have, and I know henna is extremely permanent), would it seal the permanent dye, or would it still fade underneath the henna?

Hi Strawonaberry! O.K., I've never used a commercial dye, only some herbs, oils, & wooden combs that have coloring properties; so I really don't have all the info you need, but I'll give you what I've got.

My hair is dark blonde/light brown, & I'm trying to keep it from going grey. So I normally use rosemary tea, Kalpi Tone, Jamaican Black Castor Oil, neem oil, and wooden combs made of either neem wood, cherrywood, lignum vitae, or sandalwood, to darken my hair. The result is just my normal blondette color. It doesn't look dyed. The greys are not very noticeable, & look golden. (Not bad for age 64.)

At one point, I thought I wanted red hair, so I mixed a little henna into my normal hair mask. I couldn't see any difference, so I tried more henna in the next week's mask.

It turned out a beautiful shade of orange that I didn't like; so, the next day, I crushed 4 frozen blueberries into another mask. I was thinking, "Orange + Blue = Brown."

It worked. Although I still see an occasional strand that I think looks henna-red, the overall effect is my normal color. I no longer want red hair, knowing my blondness will turn it orange.

I have also read that sometimes henna can be "oil-pulled out"; in other words, slather the hair with coconut oil & then shampoo it several times to get all the oil out. It may take several oil applications, but at least oil's good for the hair. But you haven't used henna, so I don't know if this applies to you.

I must say, I think your hair looks very nice, but everybody likes a change once in a while.

Whatever you do, be sure to strand-test first, on some of your hairs that you've recently shed.

I think that with dye it can fade in a greenish kind of color. It's too light... I'm not am expert but I think you need to dye it of a darker color and with a red undertone and then go with the dye you like.
For the henna, I think it will change drastically the color. The pink dye will still fade, but the color you 'll have is totally different.

Bonus question: what dye are you using?

The best thing to do is go to a hair salon if ones open and ask what toner they'd suggest to help cancel it out sure vthe colour wheel helps but it's not as accurate as asking a trained hairdresser what toner works for your current shade
