When do most women go grey then? "Most women who are in their 30s should see a few grey hairs, but by the time they get into their 50 most women would expect to have more than 50% of their scalp hairs turn grey."
Don't assume that grey hair makes you look older
Hair naturally loses pigment as we age, but stylist Paul Falltrick points out that the notion that grey hair makes you look older is increasingly becoming a misnomer: "Grey shades can be stereotyped as ageing, but a clean-looking grey is stunning" he says.
Some women may begin going gray in their 30s or 40s. But for others, the process may begin as early as when they're 20 years old. For some women, hair can be a form of self expression. When it begins to turn gray, some women think nothing of it or even realize that they love their new silvery strands.
As a general rule, Mike Liang, advanced colorist at Julien Farel Restore Salon & Spa in New York suggests going gray when you reach 80 percent non-pigmented or white hair. If your hair starts to feel increasingly dry, brittle, or damaged or you experience scalp irritation, it might be time to ditch the dye.
Camouflage roots. To avoid a contrast between graying roots and dyed hair, add highlights and lowlights (no more than two shades darker, within your natural color family), which will blend gray. Or cover up roots with a temporary concealer, which lasts until you shampoo.
Grey hair and genetics
The average age for grey hair varies greatly, and one of the main causes of grey hair in your 20s is genetics. The age at which a person's hair turns grey is influenced by the IRF4 gene, and one specific variant (rs12203592) is a marker for premature greying.
From the moment the first grey hair appears on your head, it can take an average of ten years for all your hair to slowly turn completely grey.
In those aged 56 to 60, 86 percent had some grey hair, with almost a third of their head having been covered. But not everyone in their 60s had grey hair. Researchers found that 91 percent of 61 to 65-year-olds have, on average, 40 percent of their hair going grey.
It depends on your skin tone and your shade of gray. Brilliant white, glossy platinum or shiny silver hair is pure genetic luck. It helps if your skin has warm golden undertones or is a rich color. When gray grows in dull, ashy or muddy, it needs help, especially if your complexion is ruddy, sallow or very pale.
Silver grey hair will look best on olive and fair skin with yellow undertones. If you have a pink tone, your skin may appear red and irritated with a cool grey hue.
2. And your hair might feel healthier. While hair dyes and techniques have come a long way since their follicle-frying beginnings, they do still leave some damage. Taking a hiatus from color will help your hair return to its previous state--especially as dyed ends get chopped off.
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.
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).
Just like one finds grey hairs on the head upon ageing, appearance of grey hair on the eyebrows is also a sign of ageing/premature ageing. While for some, these signs start showing up in the 40's or 50's, some folks encounter the problem of grey hair on eyebrows in their 30's.
The pigment in our hair is caused by melanin— the same pigment that is also responsible for our skin color. Gray hair is caused by a loss in melanin, whereas white hair does not have any melanin at all. As you age, your hair produces less and less melanin that leads your hair to appear gray, and then eventually white.
Gray blending is a subtle hair color application that oscillates between highlights and balayage. Like a game of chiaroscuro, the colorist will first lighten large sections of hair with a light balayage, then accentuate the effect on a few finer strands to blend in the gray hair naturally present.
Just like the hair on the head, the hair on the rest of the body, including the pubic area, is subject to graying. As people age, their skin produces less melanin. Melanin is the pigment responsible for giving skin and hair its color.
It turns out you can blame Mom and Dad, at least a bit. Scientists say they've identified the first gene for gray hair. The variant, dubbed IRF4, is also associated with blonde or lighter-colored hair. That makes sense, because melanin is the pigment that paints hair with the chestnut, golden or raven hues of youth.
So, he says, "Follow healthy hair habits. Try to avoid repetitive use of heat and chemical treatments which can damage the hair and the pigment cells. Limit exposure to, or protect hair from, toxins and pollutants, and when possible, protect your hair from the sun by covering it up with a hat or scarf."
Sticking to white, black and navy is a perfect way to play it safe, but still look stunning, bringing the attention to your lovely grey hair. When choosing the whites, it is advised to lean towards pure white instead of creamy, off-white shades.
