If you're dealing with a lot of gray hair, you should touch up every four to six weeks. If that sounds expensive—and time-consuming—that's where at-home coloring is key. With it, you can keep the hair color you know and love—without spending a ton.
The timing between dyes, according to Lint, is roughly every four to six weeks. If you're stretching that time gap pretty thin, however, there are methods to cover your gray roots in the meantime. "There are lots of products, such as powder or makeup, that cover your gray and then wash out when shampooed," says Lint.
You shouldn't dye your hair more frequently than every two or three weeks. The problem is when you're going blonde you can see your dark roots after a week, but if you color your hair every week, then you will see damage.
Ideally, you should be visiting your stylist for a root touch up every 4 to 6 weeks, and no later than 8 weeks. This isn't purely because it'll look better, but for biological reasons, too.
Develop Color Under Heat
Without heat, color can take 30-40 minutes to cover stubborn grays, but with higher temperatures, you're looking at 15-25 minutes.
According to hair biology experts and styling experts alike, grey hair is more resistant to color than younger hair because of its texture. The relative lack of natural oils in the hair compared to younger hair make it a rougher surface that tends to reject the color being applied, especially around the roots.
General Tips When Coloring Your Hair
Hair coloring sessions should be around four to six weeks apart. This is to prevent your hair from becoming brittle and weak. During this time, it's recommended to refresh your hair with conditioning treatments such as masks to keep your hair healthy.
Generally speaking though, it's best to wait 4-6 weeks before having another color treatment – in most cases, this is enough anyway and reduces the risk of hair damage. There are some exceptions, but in general, it's better to err on the side of caution and wait for this long.
Permanent dye is the longest lasting dye. Generally, it's safe to re-dye every 6 to 8 weeks. Permanent hair dye lightens the hair and deposits color.
As you know, one size fits none. But generally, every 4-6 weeks is a standard time between colorings. It really depends on a number of factors, like if you're changing colors, getting a new color, what type of hair you have, and which products you use.
Your environment is polluted
Pollutants and toxins can cause you to grey faster, according to the Library of Congress. These chemicals generate free radicals-or oxidative stress-that damage melanin production and speed hair aging, studies suggest. But once hair grows out of the follicle, it's dead, adds Dr.
Wait At Least 2 Weeks to Re-Dye
Trichologists (hair scientists) recommend waiting at least 2 weeks – but technically 15 days – before you re-dye your hair if it's already damaged. This is especially true if you've used permanent hair color or a high-volume developer (30 or 40 volume).
The general rule of thumb is that you can dye every four to six weeks when your roots have grown. The most important thing to remember is to treat your hair between dyes to make sure it stays hydrated and healthy.
Re-dye often, but not too often. Your hair shaft is delicate, and should only be dyed once a month or so. Any sooner than that and it will be prone to breaking, splitting, tangles and straw-like texture. Deep conditioning treatments used in conjunction with any color service are always recommended.
The peroxide has a strong dying agent which causes the hair to feel dry and straw-like. Over time, and with repeated colouring sessions, these changes in the structure of your hair will leave it weaker and more prone to breakage. The more hair is dye damaged, the less the colour holds.
After you've applied dye to one section of hair, comb through it using a wide-tooth comb. This will make sure all your hair is coated with dye, and evens out the amount of dye.
You don't need to color all your hair every time
This can result in a darker shade at the ends than roots—which may not be the best look! Instead of coloring your whole head of hair every time, just touch up your new growth with either the Madison Reed Root Reboot or the Madison Reed Permanent Hair Color.
Does coloring or bleaching your hair damage it forever — like, forever forever? In short, the general consensus among the celebrity hair colorists I consulted with is that, yes, dying and bleaching your hair permanently alters the integrity of your hair.
For grey hair coverage, we generally recommend that you aim to color slightly lighter than the natural hair color level of your client. In this case we would suggest you go for a color starting in level 6 (Dark Blonde) or 7 (Blonde).
Joico Color Endure Violet Shampoo
A brand known for products tailored to different color-treated hair tones, Joico also has a shampoo that benefits gray hair. Joico's Color Endure Violet Shampoo contains purple tones to remove brassiness from grays so that they look more vibrant. It also prevents any yellowing of hair.
' Yes, highlighting in most cases is more effective in blending grays with the rest of your hair than traditional dyeing. A simple formula: highlights to disguise gray hair are recommended when there's no more than 30% of gray hair if you're brunette or 40% if you're blonde.
Spray on aerosol hair dye for a quick fix.
Allow the dye to dry completely and then brush your hair from the roots down to blend the color. Spray-on hair dyes may include dry shampoo that will absorb oil and create texture, which will also help cover your grey roots.
