If you are looking for a low-impact, natural effect then lowlights are a safer way to color grey hair. Your stylist uses foils to apply the color so it doesn't lie directly on your scalp. That means less exposure to chemicals and fewer potential allergic reactions.
Use semi-permanent dye. There is no developer involved and just dye the strands that are grey. It's so non toxic that I can leave it in my hair without washing it out and it doesn't burn or damage. I use a baby toothbrush because I don't have a lot either and just target the area and my natural hair color is dark.
Demi-permanent hair color
This allows the color to last longer than semi-permanent colors, while reducing the damage typical of permanent options since it does not penetrate the entire hair shaft. Demi-permanents also offer more coverage, hiding up to 70% of grays.
Premature graying may be reversed with vitamin B12 supplementation only if vitamin B12 deficiency is the cause. If you are graying due to other factors, such as genetics, zinc deficiency, and medications, your gray hair cannot be reversed.
Aging Grey
Once that pigment cell is dead, it won't come back – the hairs growing from that follicle will never be coloured again. And aging is inevitable. Dermatologists often quote the 50-50-50 Rule – 50% of the population will be 50% grey by 50 years of age.
High levels of hydrogen peroxide block the production of pigment, leading to gray hair. Most men and women start getting gray hairs in their 30′s and 40′s. How much gray hair you have depends on your race (white people gray faster than Asians or blacks) and your genetics (some people turn gray in their 20′s).
The average age of onset of hair graying appears to be mid- to late forties; however, this varies with race, with the average age for Caucasians being mid-thirties, that for Asians being late thirties, and that for Africans being mid-forties.
That said, certain conditions may temporarily restore pigmentation. For example, if greying is caused by a vitamin deficiency, stress, or an underlying medical condition, addressing these issues may slow or even partially reverse greying. However, the complete reversal of naturally aged hair remains a challenge.
Unfortunately, there is no scientific evidence to suggest that increasing vitamin B12 intake can reverse existing gray hair. Hair that has already lost its pigment is unlikely to regain its natural color.
Covering gray hair doesn't have to require hair dye. If you don't have the time (or desire) to color your hair, look to hair accessories to hide your grays. A silky scarf, chunky headband, or even a sunhat can quickly cover graying strands while adding stylish flair to your everyday look.
To address pigment loss in gray hair, Kaeding said, you can use a color depositing shampoo or conditioner for temporary results. Or, for a longer-lasting solution, you can opt for permanent hair color or highlights.
Lemon juice is a popular natural lightener. It can help hide gray hair, especially in blonde hair. The citric acid in lemon juice works with sunlight to lighten hair color slowly. It may not remove gray hair completely, but it can help mix them well with the rest of your hair.
Some say that a touch of apple cider vinegar, either applied directly or mixed into shampoo, can calm, tone, and clarify grays for increased blending and manageability, while others swear by black teas or even curry leaves as a means of darkening or tinting bright silver strands via organic plant pigments.
Opt for hair dyes made with natural colorants like henna, indigo, cassia, beetroot, coffee, and other plant-derived ingredients. These natural hair dye options allow you to color your hair without harsh chemicals like ammonia, PPD, resorcinol, and peroxide commonly found in conventional dyes.
Pick a lighter hair colour
A lighter colour will then look better. Your hair follicles produce less pigment as you're turning older. If there's no more pigment being produced in the hair follicles, your hair turns pigmentless.
Context: Although the primary cause of premature hair graying (PHG) is considered to be genetic, certain environmental factors also play a role. Trace element deficiencies such as Vitamin B12, Vitamin D3, and calcium may also be associated with PHG.
A review of research suggests that proper supplementation may reverse premature graying in those who are deficient in certain nutrients, including iron, vitamin D, and vitamin B12. However, even though some supplements are specifically sold as “anti-graying,” there aren't any studies that prove they work.
Melanin rich foods like dark chocolate, blueberries, citrus fruits, nuts, leafy greens, lentils, fish and meat can help increase melanin in hair.
Typically, White people start going gray in their mid-30s, Asian people in their late 30s, and Black people in their mid-40s. Half of all people have a significant amount of gray hair by the time they turn 50. A White person is considered to be prematurely gray if their hair turns gray by age 20.
The reason why your gray hair is turning yellow might surprise you: hard water. Hard water and hair don't usually get along, and after enough exposure to minerals and metals (like calcium, magnesium, aluminum, copper, manganese, and iron) it can turn yellow.
There's no hard-and-fast rule about when (or if!) you should stop coloring your hair and go gray; it's ultimately a personal choice.
Melanin is what gives your hair (and skin) its natural color. People of African descent, Thai, and Chinese people, go grey more slowly.
