How to remove Henna from hair

[finished31]

Posting on here for traffic.

DD had her hair dyed black about 8 weeks ago with henna and it's starting to grow out. It is usually dark brown.

Any ideas how to remove the henna without using bleach. I've seen some google searches on using vodka but don't want it to end up all patchy. Her hair is waist length too.

TIA

Not sure how effective it would be, but I was told washing up liquid helps strip colour out of hair, or head & shoulders.

I’ve dyed my hair with henna numerous times and have not been able to remove it.

Oil apparently helps take Henna out but I wouldn’t bank on actually managing to fully remove it.

My hair is currently dyed over the top of it, has to be re-done quite often as the dye comes out quickly and reveals the old henna colour underneath.

Henna binds to the hair cuticle so it won’t be possible to get it out completely. Please be careful as you can cause irreparable damage to the hair this way.

I have been henna-ing for about 6 years and have considered going blonde before - I’d need bleach as my hair is nearly black. My my hairdresser won’t touch my hair for this very reason.

I honestly don't think you can. I had red henna for years, saw several hairdressers and they all refused to touch it. One offered a strand test because apparently trying to remove or redye can break all the hair

Oh and bleach gets HOT on hair that has been treated with henna so be careful whatever you do!

Head and shoulders strips most colours but I don't know if it works with henna
It's worth trying as it's non damaging

Don't use bleach! The two can react and can cause a lot of damage and it won't go blonde- instead it will go an odd bluey green colour, even box dyes will react and be unpredictable.
Oil is all that can safely be used and has proven to lift it ever so slightly, even then it won't completely go unless the hair gets cut off.
I'm not a hairdresser however have been using alternative ways to dye hair due to allergies for years and I had to learn this about henna the hard way!

Thanks everyone, I definitely won't use bleach on it.
I think I'll just have to buy one of those 'touch-up-spray' for now.

Would a semi permanent dye be ok for when the roots are very noticeable?

Do you know what brand of henna she used?

You can't.

I used to dye my red hair even redder with henna. It just has to grow out.

I used to henna my hair and my understanding was that you can't remove it - it's not like normal hairdye as it bonds to the hair. You can't even dye over it.

I let mine grow out and it took months eventually.

Moon Star herbal henna from eBay ☹️

I can't find the ingredients online, don't suppose she's got the packet still?

If the dye was just a mix of henna and indigo (which is what makes it black rather than red), then using box dyes should be fine. I've dyed, bleached and colour-removed on top of pure henna lots of times. (Never came close to removing the henna, but could lighten it slightly ) The problem is the pre-mixed brands often have extra ingredients, metallic salts etc and these are the things that react badly with bleach and dye.

Test the dye on hair from the hairbrush - if it was pure henna dyeing over it should be fine.

Black and henna is always a massive commitment - she can look at mixes on The Henna Page and see if there is anything close to the colour she would like and go from there.

if its a body art quality henna on its own you can dye over the top of it. But if its black/dark it sounds like its got indigo in, which you can't remove but it will fade with shampooing, 100g of BAQ henna and the same qty of hibiscus powder should cover it and make it more of a red/brown. It goes orangy for a few days then oxidises & calms down. If you bought a ready made mix it will probably have other things in which is what reacts badly to hair dye so don't use that, and definitely not bleach.

what I mean is it might go more like her natural colour if you henna without the indigo, so easier to grow out.

can you post a picture?

Henna turns ginger if you apply other products to it. It is far better to let it grow out.

Henna is a stain, not a dye so you can’t remove it or bleach it out. Unfortunately it’s a grow it out situation and hope it fades as it goes!

Would one of those spray-touch-ups be okay?

Henna is NOT black. Henna is a pure red dye. If her hair is black with no red tones then it wasn’t henna, but indigo. Always be careful buying henna products online as if they’re not from a reputable company they could have anything in them.

Either way, you cannot remove these. They are more permanent than permanent chemical hair dye.

Spray touch up would be fine

Green Fairy washing up liquid is very good at stripping all sorts out of hair. I heard once that Twiggy swore by it too lol

Thank you so much everyone. I wish I'd of refused to do it but she banged on about how it's not harsh on the hair as her friends have all used it.
