This scientific information has been documented in a research paper available on PubMed.
Are older individuals with darker hair more likely to pass on the trait to their offspring?
The color of a baby's hair is determined by the active genes inherited from their parents. The specific hair color genes that are turned on or off during development ultimately determine the baby's hair color. The likelihood of the baby inheriting a particular hair color from one parent over the other is influenced by the parents' own hair color. If one parent has darker hair and the other has lighter hair, the baby is more likely to inherit the darker hair color. Thus, the baby's hair color is influenced by both genetics and chance.
Is hair loss genetic?
Androgenetic alopecia, commonly known as male/female pattern baldness, is the only type of hair loss that is inherited from parents to offspring. While both males and females can be affected, female pattern baldness results in a general thinning of hair on the top and sides of the scalp rather than total baldness. The genetics of this condition are complex and are inherited from both parents, making it difficult to predict the likelihood of developing it.
Does hair color change with age?
Hair color is a trait that can be determined by genetics. In people of European descent, hair color may change over time from lighter shades to darker shades.
