"I dye my hair regularly and it fades so quickly. I'm confused, because if it's permanent, doesn't that mean that it shouldn't fade? How long does permanent hair generally last? I want to know if mine fades more quickly. And if my hair color fades too fast, how can I prolong my hair color? And while I have you, what unnatural hair colors last the longest? Show
Thanks for writing, Deepti! We'll answer your questions one by one. How long does permanent hair dye generally last?Permanent hair dye typically lasts for between four to eight weeks before it grows out or fades (more on that below). That timeline is broad because it depends on a lot of different factors - how fast your hair grows, the amount of contrast between the color that you dyed your hair and the color it is naturally, the method that your stylist used, how damaged your hair was pre-dyeing, et cetera. To illustrate: someone who gets a balayage, a style in which the dyed color is integrated smoothly into the hair's natural color, will be able to wait longer than someone who dyes their naturally light blonde hair raven black from root to tip. The person with the balayage will be able to grow their hair out easily - balayages subtly transition from your ends to your roots, so there's no clear demarcation of color. Our balayage friend would be able to go weeks and weeks between appointments, since their roots look natural. Meanwhile, our blonde to black friend would need to get a touch up the instant their roots start showing, since there's such a strong contrast between blonde and black. Depending on how fast their hair grows/their comfortability doing touch-ups at home, they might have to be back in the stylist's chair in under four weeks. Does permanent hair dye fade?Permanent hair dye is interesting, because while it is indeed permanent (you'll never be able to remove it completely from your hair without bleach), it does change color and morph over time. Permanent hair dye lasts until it grows out, but it might not always keep the exact same color. The color that it fades to and how quickly it fades depends on multiple factors, including:
The list goes on and on. Because there are so many things that can influence the rate at which hair color fades (and the exact color that it fades to), it's challenging to predict exactly how long a dye job will last before a retouch is needed. Of course, that's assuming that the person actually wants a retouch - it could be that they love the color that their hair faded to (this really does happen! Faded colors can look pretty cool) and don't mind having obviously grown out roots. "My hair color fades too fast, how can I prolong my hair color?"If you want your hair color to fade more slowly, here are some best practices:
And what unnatural hair color lasts the longest?Green and red fashion colors can last the longest. Second in line are any dark colors. Pastels fade very quickly. Broadly speaking, darker colors of hair dye last longer. However, the amount of time that a color stays largely depends on the brand of hair dye that you use. Some of the best brands of hair dye in unnatural colors that last long are Punky Color, Manic Panic and Arctic Fox. Can I dye my hair red without bleaching it?Good news – most of the intense and dark red hair dyes don't require bleaching your hair in advance. Our new red hair colours will work on dark blonde, medium blonde and light brown hair colours. To colour your hair you will need to mix hair dye with developing lotion.
How many washes does red hair dye last?The first thing to know before going red is how high-maintenance the color is and how expensive it can be to maintain it. Roots will reappear every four weeks or so and red dye is infamous for fading fast. You'll have to dip back into the salon roughly every six weeks for a refresh on your color.
Why red hair dye fades quickly?The red hair molecule is larger than other color molecules, so it doesn't penetrate the cortex of the hair as deeply as other color molecules. Therefore, since it isn't as deep, it can wash out easier. Red hair dye may be more inclined to fade, but it can also be one of the most vibrant, unique ways to color your hair.
How long does permanent red hair dye last?Ideally, permanent hair colour would stay just as vibrant as it was the day you coloured it, at least until the roots grow. On most heads of hair, that would mean a good 6-8 weeks between touch-ups.
