CROWNING GLORY JUST LIKE MUM’S

her mother had dark hair as a child, while her father was a blond baby — and Charlotte seems to be halfway between the two, with a full head of downy, chestnut hair.

It’s common for babies to be born with lighter hair, due to low quantities of melanin — which gives pigment to the hair in the same way as the eyes and skin — in the body at birth.

The fact Charlotte is already a brunette suggests she will stay this way as she gets older. This is because dark hair genes are more dominant than light hair genes — meaning that if one parent is darkhaired, their child is likely to inherit this colour over blonde.

Kate is said to wash her daughter’s hair with shampoo from the organic Babies range (£6.50), a natural product containing aloe vera, chamomile and lavender.

Most parents don’t cut their baby’s hair until they reach their first birthday, so Charlotte is unlikely to have had a trip to the royal hairdresser just yet.
