De ce copiii blonzi ajung adesea șateni sau bruneți? Misterul pe care oamenii de știință încă nu l-au rezolvat • Newsweek România

Many children with blonde hair in early childhood often transition to darker shades like brown as they grow. This phenomenon is common, with studies showing that a significant percentage of these children develop darker hair later. The exact reasons behind this change remain unclear, although it is known that melanin production increases with age. Hormonal changes during puberty may influence this process, but no simple mechanism has been identified. Genetic factors also play a role, as predictions based on DNA do not always align with the actual hair color observed later in life. Thus, the evolution of hair color in children is complex and varies significantly among individuals.
