10. Piebaldism is a melanocyte or pigment cell disorder that results in a section of white hair at the front hairline.

11. Less than 1 in every 20,000 people worldwide have piebaldism disorder.

12. Black and brown hair: Up to 95% black or brown eumelanin and approximately 5% pheomelanin.

13. Red hair: About 33% pheomelanin and approximately 66% brown or black eumelanin.

14. Blonde hair: About 33% pheomelanin and approximately 66% brown eumelanin (no black eumelanin).

15. L’Oreal Paris leads the women’s hair coloring market share with almost 38% of the market sales.

16. The type and amount of melanin in the hair are determined by many genes, although little is known about most of them.

17. In the 1950s, 7% of American women dyed their hair.

18. Blond hair is more expensive and will cost up to 3x more than dark hair.

Hair and Eye Color Combination Statistics

19. Hair color is determined by pigment or melanin in the hair.

20. Eumelanin, another melanin or pigment, determines people’s black or brown hair.

21. Another pigment, called pheomelanin, gives people red hair.

22. Very little eumelanin gives people blonde hair.

23. Hair colors are passed down through generations.

24. Hair colors are a spectrum of hues ranging from white blond to coal black.

25. The genes involved in hair color also influence eye and skin color.

26. The genes responsible for hair color aren’t dominant or recessive.

27. Red hair and green eyes are the rarest hair and eye combination.

28. The MCR1 gene dictates whether you have red hair and is recessive. It depends on whether genes are turned on or turned off.

29. Our DNA has 20,000 genes. Only a few of these genes dictate hair color and eye color.

30. A pigment called melanin determines our hair, eye, and skin color.

31. The MCR1 gene comes in two variants: non-red and red. The non-red version is dominant.

32. Gey, one of the genes determining eye color, comes in two forms: green and blue. Blue is the dominant allele.

33. Alleles of the gene OCA2 determine whether someone has brown or not-brown eyes.

34. Red hair is rare because it’s a recessive trait that occurs only when a person has 2 copies (one from each parent) of a mutated melanin-conversion (pigment changing) gene.

35. 25% are the chances of a red hair person having a child with red hair with someone with dark hair who carries the red hair gene mutation.

36. The best-studied hair-color gene in humans is called MC1R.

37. The MC1R gene provides instructions for making a protein called the melanocortin 1 receptor, which is involved in the melanin pathway.
