Human DNA has millions of on and off switches along networks that control how genes function. Genes responsible for hair color come from both parents. Although the genes passed down from a child's parents determine hair color, variations can result in a child having a different hair color than both parents.
At what age do babies get their real hair color?
A study found that many babies (both male and female) had darker hair for the first six months of life, and lighter hair between 9 months and 30 months of age. Then, after the age of 3, the subjects' hair became progressively darker until they turned 5.
What colour hair are most babies born with?
A study published in Forensic Science Communications recorded the hair color of 232 white, middle-European children in Prague. They uncovered that many of the children, both boys and girls, had darker hair in the first half year of life. From 9 months through age 2 1/2, the color trend lightened.
Will my baby have ginger or brown hair?
If, like your parents, your partner is carrying a single ginger hair gene along with a single brown hair one, then your children will have a 50/50 chance of having ginger hair.
What is the rarest hair color?
The rarest natural hair colour is red, which makes up only one to two percent of the global population. You commonly see these hair colours in western and northern areas of Europe, especially Scotland and Ireland. However, natural redheads may not exist for much longer.
How do you tell what colour hair your child will have?
Hair colour is determined by a mixing of genes from both parents. Darker hair is more common than lighter hair, just as brown eyes are more common than blue eyes. This is due to the dominance of the genes that express these colours.
