Question: can your hair turn from blonde to brown

Answer: Yes, Blond (or blonde for women) hair ranges from nearly white (platinum blond, tow-haired) to a dark golden blonde. Strawberry blond, a mixture of blond and red hair, is a much rarer type containing the most pheomelanin. Blond hair can have almost any proportion of pheomelanin and eumelanin, but has only small amounts of both. More pheomelanin creates a more golden or strawberry blond color, and more eumelanin creates an ash or sandy blond color. Many children born with blond hair develop darker hair as they age, with the majority of natural blonds developing a hair color of a dark blond hue by the time they reach middle age. Pregnancy hormones hasten this process. Natural light blond hair is rare in adulthood, with claims of the world's population ranging from 2% naturally blond to 16% in the US. Blond hair is most commonly found in Northern and Western Europeans and their descendants but can be found spread around most of Europe. Studies in 2012 showed that naturally blond hair of Melanesians is caused by a recessive mutation in tyrosinase-related protein 1 (TYRP1). In the Solomon Islands, 26% of the population carry the gene; however, it is absent outside of Oceania.
