Meghan Markle’s appearance may give us a huge clue on when her baby’s arrival will be.

The Duchess of Sussex and the palace has not confirmed how many months along Markle is in her pregnancy. However, Jane Mayhead, senior trichology consultant at The Private Clinic of Harley Street, said that based on her hair volume, she’s already around the six-month mark.

Based on Markle’s recent images, her locks appear much fuller than before her pregnancy, which is possible due to changing hormone levels.

“The increased levels of hormones during pregnancy can cause the growth cycle of the hair to increase, meaning the hair is less frequently renewed and replaced at the site of the follicle and women will experience thicker and shiner hair,” Mayhead told Express.

“I tend to find that most women will experience some level of increased volume by around the six-month mark,” she added.

Considering the numbers, it’s possible that Markle will give birth in March. Mayhead added that the change in her hair could also be due to Markle changing the types of products she is using to protect her unborn child.

According to the hair expert, the hair normally grows at a rate of around 1 centimeter each month, but this is faster during pregnancy. However, the most significant change that a pregnant woman will experience will be in volume due to less hair fall and change in the growth cycle.

Meanwhile, odds suggest that Prince Harry and Markle’s firstborn will arrive in April. Kensington Palace only said that the upcoming royal baby is due in spring which will start on March 20 and end on June 21.  Corals have slashed the odds of the Duke and Duchess of Sussex welcoming their baby in April to 6/4.

In related news, Prince Harry and Markle’s baby is expected to work for a living. Their children will not carry out full-time royal duties that are expected from Prince William and Kate Middleton’s kids.

They would be in a similar situation as Prince William and Prince Harry’s cousins, Princess Beatrice and Princess Eugenie. The two daughters of Prince Charles’ brother, Prince Andrew, have charities, but both are not full-time working royals. Princess Eugenie also has a full-time job. She’s a director at Hauser & Wirth, a contemporary art gallery in Mayfair, London.
