Report: This may be the reason Meghan Markle ditched her signature messy bun

Just like Kate Middleton is known for her signature sleek blowout, Meghan Markle's messy bun has become the royal's signature look.

Even before assuming her role as duchess and marrying Prince Harry, the actress was known to channel her laid-back California roots with both her fashion and beauty choices. Particularly, the royal became quickly known for her loose buns, which she most famously debuted on her wedding day in 2018, much to the criticism of many for its "messiness."

And while the royal's post-partum appearances have been few and far between, it's clear that the new mom has ditched her signature 'do in favor of sleek updos, a move that's been characterized by many hairstylists as a prudent choice given the effect giving birth might have on hair and skin. The Duchess of Sussex's royal red carpet debut at "The Lion King" premiere on Sunday was the fourth time she's been spotted with the hairstyle following Archie's arrival.

"When you're pregnant your hair cycle stops so you don't shed any hair, so when you give birth, all the hair you should have lost in the nine months falls out over a quick period," said hairstylist James Johnson to The Daily Mail.

He speculates, "Meghan may have opted for a scraped back bun to prevent her hair from further damage. It's also a quick hairstyle and perfect for hot weather."

If Meghan is facing post-partum hair loss, she's not alone.

Post-partum hair loss, also known as postpartum telogen effluvium, is very much normal for new mothers due to the changes in hormone levels after giving birth -- in fact, it occurs for about 60 to 70 percent of women. And while some new mothers may only experience minor hair loss, others may notice large chunks missing from their scalps and hair falling out in "fistfuls."

The condition takes place around three to six months after delivery and can last another half a year. It can be particularly stressing for these new moms, who are already grappling with the effects of their body after giving birth.

"As humans, the appearance of our hair is closely linked to how we feel about ourselves. Hair loss commonly impacts self-esteem and body image. Women with hair loss feel less attractive and increasingly self-conscious," said dermatologist Jeff Donovan to HuffPost.

And while doctors maintain there isn't anything pregnant women can do about hair loss after birth, many are reassured by the fact that their "hair will probably restore itself naturally," explained dermatologist Jeffrey Rapaport to Self.
