What would happen if I put light brown semi permanent dye on my mid brown hair?

[SoManyDandelions]

In an ideal world, it would dye my grey strands light brown and be invisible on my mid/dark brown hair. I have a few grey strands that are starting to become more noticeable. I assume there is a reason why this wouldn't happen though?!

When I used a mid brown box dye, it covered my greys for a while but made the rest of my hair darker. So when the greys re emerged they were even more visible 😬

I don't want to go to a salon. Thank you!

I have dark brown hair and have started using mid brown hair dye to hide the greys and it does work. My hairdresser advised me to do it - I think she suggested a 5.5-6 for my hair but I could be making it up so let me google. But has definitely worked for me

Is it a semi-permanent or permanent dye?

I always use permanent even though it fades really quickly on my hair

It won't lighten the darker hair but will make your virgin hair a different colour

Have googled and I use a 6 and my natural hair colour is dark brown

I do this, it basically gives me chestnut fine highlights on my few grays. Hairdresser was flabbergasted to learn I'd done it myself, said it looked like a really good job. I wouldn't do it with permanent dye but only with semis.

Why wouldn’t you do it with permanent? Would semi be better? I have only ever used permanent

My experience is you'll always end up with a red/ orange hue that will be a bastard to get out and haunt you forever ( not a problem if you're wanting 'warm').

Thanks everyone - sounds like it could work!

I use dark blonde semi permanent on my medium ash brown hair with grey in it. Comes up a lovely honey brown so adds warmth, and my greys become blonde highlights. Always go lighter than darker as they often come out darker than expected

I haven’t used permanent for years as I found it lifted my natural brown hair colour and then it became a brassy orange/red when washing out. I also found it gave all my hair a one tone colour that looked not so natural and my hair really suffered.

I did this but it just made the great coming though a different colour to the rest of my hair and do not last long. Also went abit orangy too after a few washes. I have given up on home.haor dyes and just go to the hairdresser for my roots doing. I put 10 pound a week away towards my hair and just seen it as my treat to myself.

I'm naturally dark brown and use a medium ash brown semi to cover greys. Works really well.
I did try a light brown to take it a bit lighter and to not make the regrowth so visible. Looked nice for a week, then goes orange!

Went orangey all over for me. Elumen however just dyes the greys if you can make it stick to the roots.

It's not my roots that are grey, as I've not used any sort of permanent dye on my hair for 15 years. It's just random long strands mixed in with my brown.

I don't want orange or warm. Maybe I'll just carry on with Plantar 39 brown shampoo!
