Semi Permanent hair dye is NOT intended for long-term hair color. And as someone who works in the corporate world, but enjoys having fun every so often, there are MANY people who want to go a different color for just a few days/weeks.

Not everyone wants to have bubble-gum pink hair, or turquoise blue hair for years on end.

As for getting the dye out in 10 hours, you're kinda stuck - and I know that it's past the time you need this info, anyway. You need at least 24 shampooings, which can really damage your hair if you try them all in a row. Try to make sure you have a few days, at least, to remove the dye, and get a clarifying shampoo (the original neutragena shampoo should work well, but Rusk makes one, and a few others do, too). I've been told the more sun exposure the color gets, the faster it will fade, too.

Worst case - get a permanent hair dye that matches your original hair color as best you can, and dye over it. This doesn't ALWAYS work, but its a last-ditch effort, after all.

Try taking a hot bath, soaking your hair in it. One brand I used, unintentionally when taking a hot bath with my hair hanging in the water, it ran out and looked as if it never was died at all. It was a dark red brown on my blonde hair. It was in for only like 5 days before that bath incident happened.

HOW CAN I REMOVE SEMIPERMANENT HAIR COLOR FROM MY HAIR?

DON'T USE PERMANENT DYE OVER OR TRY TO BLEACH SEMI PERMANENT DYE UNLESS IT'S REALLY FADED!!! I learned the hard way (11 years ago) it litterally blows up your hair cuticle and snaps it off. Your best bet is hot water and dish soap the pool water works okay in the sun.

You could re-bleach it to lighten it. that's what I'm doing right now. It WILL fry your hair but that can be repaired. my mum who's been a hairdresser for 20+ years advises against this but got me the professional stuff anyways.

I'm using a 20. ..think I shoulda gone 30.

I'll post the results and tell ya if it's worth it.
Oh yeah, my hair is bright pink fetish, dyed it 2 days ago but it came out streaky...very,very streaky.

Well, it got the pink out and didn't fry my hair so maybe it's worth it.

I have heard that dish soap like Ivory or Dawn works, can anyone concur?
