Permanent hair color can lighten, darken, or change the tone of your hair; and it'll last about six to eight weeks. It often needs a root touch-up about every four weeks because dark roots are noticeable as the hair grows out, especially if hydrogen peroxide was used to substantially lighten your natural color.
Ideally, *permanent hair colour* would stay vibrant forever, or at least until the roots grow. On most heads of hair, that would mean getting a good 6-8 weeks between touch-ups – but sometimes, even with permanent dye, colour fade can happen within a few weeks.
Does permanent hair dye fade? Sadly, yes. While permanent hair dye won't wash out of your hair in the same way that temporary, or semi-permanent hair dye does, it will eventually start to fade and change shade over time. The colour you go for will also influence how long your hair will stay vibrant.
Generally speaking, permanent hair dyes need at least 30 minutes to penetrate the hair shaft fully. Leaving it any shorter could result in uneven coloring or fading faster than expected. On the other hand, leaving it for too long can cause damage to your scalp and tresses.
Leaving a permanent or semi-permanent dye in for too long can damage your hair and strip away essential moisture. The longer you leave a permanent or semi-permanent dye in, the deeper it penetrates into your hair cuticles and can cause irrevocable damage.
No, you should not leave permanent hair dye in overnight. The standard recommended time for leaving hair dye in is typically around 20 to 45 minutes, depending on the product and hair type. Leaving hair dye in overnight may lead to over-processing, hair damage, and an undesirable color outcome.
When Should You Wash Your Hair After Coloring? For any hair type that receives a hair color treatment, it is best to wait at least 72 hours before washing your hair. This way, hair cuticles can have more time to seal in color and prevent it from bleeding out or washing out too quickly.
DON'T: Wash Your Hair the Next Day
"It allows the hair cuticle more time to close and lock in those beautiful, newly added tones," adds Debski, who advises her clients to hold off from their first rinse for at least a full 24 hours.
A: Yes, salons typically use shampoo after dyeing hair. Shampoo helps to remove any excess dye and ensure that the hair is thoroughly cleansed. Also, many dyes require a special shampoo to be used afterwards to help maintain the color and keep the hair healthy.
The most durable hair colours are brown permanent colours. What Hair Colour Fades Most Rapidly? Red hair colours, particularly intense and brilliant red tints, fade the quickest. Choose auburn or red-brown tones of red if you want a longer-lasting red hair colour.
Some, particularly permanent hair dyes, alter the structure and makeup of the hair. Many hair dyes can damage both the inner and outer parts of the hair shaft. Both natural and synthetic dyes may weaken hair, but permanent dyes may cause more damage as they penetrate deeper into the hair shaft.
Permanent hair dye (like the name suggests) is designed to last longer than temporary and semi-permanent hair dyes, however, it still doesn't last forever. Unlike semi-permanent hair dye that's designed to last just a few shampoos, permanent hair dye penetrates the hair strands more, locking in the colour for longer.
Specifically, permanent hair dye lasts about 6-8 weeks. This is different from the other types of hair dye. Temporary hair dye doesn't really hold on to hair and can be rinsed away easily, whereas semi-permanent and demi-permanent hair dyes last only about 6-8 washes because the pigment simply coats the hair.
Not only do you get the environment of the salon and the skills of your stylist, but you also get professional-quality hair dye that will last much longer than a kit that you bought at the store.
Grow Out Your Hair
It may seem obvious, but another way to get back to your natural hair color is by growing your hair out. It can be a useful and low-maintenance strategy if you do it right and it can save your hair from a lot of damage.
"After having your hair colored, wait a full 72 hours before shampooing," says Eva Scrivo, a hairstylist in New York City. "It takes up to three days for the cuticle layer to fully close, which traps the color molecule, allowing for longer lasting hair color."
For shorter hairstyles like a blunt pixie or a lob, it can be easier to dye your hair before you cut it all off. Removing length means there's a lot less to work with and we can section hair for color easier.
When you do wash your hair, use as cool of water temperature as you can to help preserve the vibrancy of the color. Hot showers may feel good, but they're anything but good for your brand-new, gorgeous color do.
If you lather your strands with shampoo immediately after a color service, it may take a toll on the vibrancy of your hue. That's why VanDyke recommends giving your hair a bit of a post-salon breather. “I generally tell my clients to wait 48 hours before they wash their hair,” VanDyke says.
Avoid Washing for 48 Hours
There's a low chance you'd want to wash your hair just after getting a cut, color, and style, but on the off-chance you get a hankering to hop in the shower we suggest you press pause. Celebrity stylist Cody Renegar says this helps the pigment settle into your hair.
Healthy fresh hair will absorb the hair color better and give you an evenly distributed hair color. Now, most dyeing kits come with conditioners themselves. So you can use conditioner right after dyeing your hair to lock in the color and ensure it lasts a long time.
Mistake number four: Avoid washing color-treated hair with hot water temperature. The heat opens the cuticle, and hot water will dry out your hair and wash away hair color. Instead, use cooler temperature water when washing your color-treated hair.
Do not rush unnecessarily when rinsing the freshly dyed hair. Rinse your hair until the water runs clear. If the water is even slightly colored, continue rinsing. Then apply shampoo and conditioner.
Your best bet is to invest in sulfate-free hair care products, like Ever Pure Shampoo and Conditioner. It will allow you to cleanse your hair and remove grime and excess oil without stripping away the color from your hair. At all costs, stay away from clarifying shampoos.
