Study individuals were derived from the UK Biobank cohort that consists of 502,655 individuals aged between 40 and 69 years at recruitment, ascertained from 22 centres across the UK between 2006 and 2010. The study was approved by the National Research Ethics Committee, reference 11/NW/0382, and informed consent was obtained from all participants as part of the recruitment and assessment process. From these, we analysed 343,234 unrelated individuals, who reported their background as “British” and with similar ancestral backgrounds based on PCA16. Genotypes for more than 800,000 SNPs and indels were directly assayed by UK Biobank using custom Affymetrix arrays, and an additional ~40 M variants imputed using the Haplotype Reference Consortium panel16.

If you're highlighting just two strands, you may be able to lighten your hair naturally at home for this one.
Dominant/Recessive Gene Relationship
The red color is caused by a series of mutations in the MC1R gene, which transmits to the hair more pheomelanin; this also results in pale skin. The arrangement of amino acids in the protein for red-haired people differs from that in people having other color hair. Red-haired people suffer a lot due to a higher risk of sunburns and skin cancer since the pheomelanin does not protect the skin from sunlight. The GH Beauty Lab regularly tests at-home hair dye with both consumer testers and in controlled Lab tests.
Can certain foods boost melanin growth in hair?
Baby hair color predictors may offer generalized estimations through observable traits of parents and grandparents. However, they frequently fall short of providing precise predictions. Examples include using UV-protective products and practicing proper hair care. These practices can help preserve the integrity of our hair color. For example, environmental influences and medical conditions can significantly shape our hair colors and appearance.

Genetics of Hair Color
If you plan on dyeing your hair when it’s in a porous state, make sure to go for a level or two higher (or lighter) than your desired end result. According to this theory, diversity in hair color may be the result of more eye-catching hair colors arising by chance, and those rare colors giving their owners an advantage when it came to attracting a mate. Better success at attracting a mate would have meant better success at producing offspring, who would then carry the genes for new hair colors and pass them along to their own offspring. If you'd like a bleach-free, low-commitment way to change your hair color — try a copper hair gloss. It will give blondes a temporary strawberry blonde hue, and brunettes like Rashida Jones an amber tone in natural lighting.

Why do we have different hair colors? Research reveals the genetics at play
We love that the ammonia-free formula processes in less than 20 minutes and promises minimal swelling of your strands, which can be damaging. This non-committal demi-permanent treatment only lasts for up to 24 shampoos and leaves hair super shiny. L'Oréal makes some of the most affordable hair dyes in both the professional and drugstore categories.
This gene provides instructions for making a protein called the melanocortin 1 receptor, which is involved in the pathway that produces melanin. The melanocortin 1 receptor controls which type of melanin is produced by melanocytes. When the receptor is turned on (activated), it triggers a series of chemical reactions inside melanocytes that stimulate these cells to make eumelanin. If the receptor is not activated or is blocked, melanocytes make pheomelanin instead of eumelanin. Most people have two functioning copies of the MC1R gene, one inherited from each parent.
In the Lab, our scientists dye human hair samples in black, brown, red and blonde shades and visually evaluate each for color results and gray hair coverage. The very first thing you must understand before coloring your hair is the levels of hair color. Natural hair colors are organized into levels from 1 – the darkest (black) to 10 – the lightest (blonde).
A few gray and white hairs will blend in sufficiently not to be noticeable, but as they become more widespread, there will come a point where a semi-permanent alone will not be enough. The move to 100% permanent color can be delayed by using a semi-permanent as a base color, with permanent highlights. It looks black from afar, but up close, you can see that it’s brown. Most black women have dark brown hair, and the number 2 hair color will often match perfectly. The Garnier Nutrisse hair color line offers 38 shades in cool, neutral, and warm tones with a few unique choices.
