How to make bright hair dye stay in longer?

First bleach the desired amount of hair to a pale blonde. Once that is done make sure the area is 100% dry. Apply the color with a color brush and foil. Let it sit for 45 mins out of heat or 25 with heat. Once it is done processing run a flat iron over the foils a few times then let them cool. Rinse with cold water and sulfate free shampoo. Dont shampoo your hair the next day. Use hair powder if you need to. When you shampoo your hair again always use cool water and sulfate free shampoo.

wash in cold water only thereare special shampoos also try not to wash to often

My hair is pink / purple / black, and this is how I'm keeping mine awesome

I bleached my hair out almost platinum blonde, then used N'Rage demi-permanent hair colour (you can get it here: http://www.sallybeauty.com/n-rage/SBS-240686,es,pd.html) in Bubblegum Pink and Plum Purple.
The purple is aces good; it's not faded at ALL and I've had it in for over a month. It does tend to tint the pink, and I will say the pink kind of sucks, but I refreshed it with Kool-Aid, believe it or not.

(I used 2 packets Strawberry Lemonade and half a packet of Cherry unsweetened Kool Aid to make my refresher )

N'Rage is a damn good brand as far as bright and long lasting colours go. And you don't have to give up washing your hair (too much - I'd say 1 - 2x/wk with regular shampoo or daily with dry shampoo. LUSH makes an awesome dry shampoo that smells like citrus)

Best way I have found to keep The brand Special Effects dye in is to wash hair every other day in cold water with color protection shampoo and conditioner. Washing your hair in white vinegar sounds strange, smells gross, but it locks in the color as well. Also adding some of your dye to your conditioner help redye it after every shower, makes colors last longer too.

I have just my hair and want to do hot yoga is that possible without damaging or having the color fade away?

i youst to use directions and or stargazer at the moment im using willed light real red , you can leave it in till your bored of it being on you head i would also recommend piling all your hair on your head and then wrapping your hair in clean film the heat will help the color develop stronger
baby shampoo is the best ting i can suggest using on your hair its so milled it doesn't damage your hair and leaves it soft use conditioner after to keep the color in but

I left hair dye in all night long, literally slept in it, and... Well it lasted two years. I think the brand was called splat. I finally just cut the the rest of it off the other week. I think it was the brand I used more than leaving it in for so long. You just do not want to leave bleach in your hair for long. But it helps. Here's the page I got that tip from: http://www.gothfashion.info/hairdye.php

usually adjusting all your hair products to color protection products do help. when I dyed my hair I also used color protection shampoo and conditioner - it also helps the color stays as it is, even until my hair grows out.

i could never bring myself to give up my hot showers, but i never leave my shampoo in for more then a sec. it hardly needs it,ya know.? leave your conditioner in for AS LONG as possible. (that's the trick in my eyes) also, blowdrying when your dying works WONDERS, and if you're a go-hard like me, SLEEP WITH THE SHIT IN. it makes your hair soooo healthy, and the color lasts foreverrrr. just put a bag on your head.! (but don't put the side with writing on your head haha) then when you wake up it's dry, (if you're not using a natural product, don't do this. but if it's manic panic, color jam, raw, nrage color or anything like that. DO IT) and you can straighten it (on a very low heat) and it will literally last longer then any other time you have dyed your hair. trust me. x)

directions is fine to leave in for a long time, i normally put it it pop on a shower car (or cling film) to keep my head warm and sit watching a film or crafting for the day longest i think i've kept it in was about 6hours although only do this with dyes that contain no beach, peroxide ect, also to make it go a bit further i mix the dye with some conditioner its makes a pot go a bit further and leaves my hair silky soft ^^

You should NEVER put dye with developer in your conditioner, but there are plenty of protein fillers on the market that not only condition but will also deposit color.
I've had great success with over/double-processing dyes without bleaches and peroxides (a process described partially by KirstyL.) , cold water washing only, and making a hair mask with small amounts of your color and any heavy conditioner.

I dyed my hair with special effects atomic pink. I was able to keep it for 6 months plus. I just would not fade. I mixed it with 40vol lift and put it on and lift it in for almost 12hrs. It was bone dry. I rinsed it with cold water. Then washed it only once every week. I eventually tried to bleach it out. It would not come out... It was ridiculous. I dyed over it with dark brown and you could still see it. It eventually grew out. And mostly got cut out. This photo is untouched.

Washing with cold water and using sulfate free shampoo and conditioner are the absolute best two ways to keep your color. Also, don't let your hair air dry, always blow dry after and even without unnatural colors you're actually never supposed to wash your hair more than 3 times a week.

If you've got a local Lush Cosmetics I use their products which keeps the hair bright and healthy from application til 3-4 months. For me I've found using 2 tablespoons of a Lush Liquid Conditioner (I most recommend Retread for Damaged hair) in your hair dye (i use directions) and mixing will condition the hair and lock the color in. I leave it on for as long as possible, I recommend doing it on a stay at home day or lounge around weekend. Be careful not to put in too much conditioner as this can lighten the shade. I've left mine in for 26hrs before, you can sleep in it by wrapping your hair in clingfilm or plastic bag (helps soften your hair and lock in the intensity of the dye), Then just rinse out and shampoo, you can use cold water but I'm not as brave and just rinse it out as I would normally.

As for aftercare, I would still VERY MUCH recommend Lush products, hey don' strip out the colour and keep it at maximum health regardless of how often you was your hair. Products I personally recommend is the Trichomania Solid shampoo (what I use: made of coconut and vetivert) or most of the shampoo bars from their conditioners. If stuck on what to use just go on the website Lush Cosmetics or go into one of their stores and ask the staff. They're super friendly!

My hair colour lasts for months on ends and only needs doing when my roots grow through, WHATEVER YOU DO don't use tresseme products. I've found using them strips the hair of both colour and conditon.

Hope this helps xx

I actually just use dry shampoo to keep it up most days then just don't wash nearly as ofter
