The outer cuticle layer of greys can be more tightly packed and layered, making them resistant to colour absorption. As a result, it can be more difficult to colour resistant grey hair and to cover visible regrowth.
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.
Grey hair is often more challenging to dye than regular hair for a couple of reasons. It has a coarser texture, and grey hair follicles also tend to be drier, as they produce less oil. Because of this rougher surface, color has a tougher time penetrating these hairs.
Colors like butterscotch, light auburn and golden brown, or ash brown for those with a cool skin tone, are all versatile brunette shades that aren't too dark and are some of the best hair colors to hide gray.
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).
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.
Gray hair can be colored many different shades, such as platinum blonde, medium brown, or pure black (for this color, we recommend Simply Color Jet Black 1.0).
As with choosing a hair color, you should be careful when choosing a shade. Not all shades can 100% cover grays and could result in grays shine through. The most suitable shades for dyeing gray hair are considered to be natural shades, which are able to 100% cover white hair.
Wait 20 minutes for the roots to process, then it's time to refresh your ends. “Take sections of your hair, from the top, and apply the colour through the lengths of your hair. When you feel that you've saturated all the ends, leave it for ten minutes, and then shampoo,” Josh advises.
If you leave hair dye on for longer than recommended, it'll cause your hair to become dry, brittle, and prone to breakage. Lastly, make sure you use a salon quality shampoo and conditioner after coloring your hair. It'll help the colour last longer, remain vibrant and feel salon fresh.
Brittle, split, and dry hair won't take hair dye the same way healthy hair does. If your hair is damaged, the dye's chemicals will penetrate the hair cuticles differently, and you may end up with patchy or faded color. Prep your hair before you color to make sure all your strands are as healthy as they can be!
Your Hair Dye Didn't Sit for Long Enough
The developer needs time to penetrate your hair's cuticle. Typically, you should let your dye sit for 30 to 45 minutes. Always follow the time specified on your specific bottle of hair color. Stick to the higher end of the time range if your hair is prone to not taking color.
' 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.
If you want to color your hair at home, you can use box dye to cover grays, Kyan says.
New, undamaged hair, such as the kind found at your roots, has a much stronger outer layer and does not loosen up enough to let as many color molecules in. When the color molecules can't get into the hair, they can't change the hair color.
Shampoos with colour effect
These are temporary toners that build up the colour effect with each use but can be washed out. This conceals the first grey hairs or light roots. Furthermore, the hair colour is freshened up and given more colour brilliance.
Always Use a 20 Volume Developer
Gray hair tends to be resistant and typically takes longer to grab hold of the hair. Since there is no pigment, there is no need to lift. You just need to open the cuticle enough to deposit the color.
Demi-Permanent or Semi-Permanent Color
While a demi-permanent or semi-permanent hair color can be applied to any level of gray, it's often used to camouflage early grays, giving 30-70% coverage.
How often is it safe to go for color? 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.
The outer cuticle layer of greys can be more tightly packed and layered, making them resistant to colour absorption. As a result, it can be more difficult to colour resistant grey hair and to cover visible regrowth.
Hot roots occur because the heat from your scalp causes the colour at the roots to develop faster than the colour on the mid-lengths or ends. This can lead to a lighter colour result at your roots than the rest of the hair.

Similar to 5 volume, 10 volume can be used with permanent color lines for depositing color, however, it will not offer much grey coverage or lift. If the hair is a finer fabric it could over a slight one level lighter shift in base color and grey blending.
As a general rule, wait at least four weeks, and preferably six weeks, before starting another treatment. Semi-permanent hair color can be used more frequently than permanent tints if desired.
