Speaking toMamamia,Bartel explains she noticed a change in her hair several months after giving birth.

“Two months ago (when Aston was about four months old) I noticed lots of my hair falling out in clumps and my hair is much finer and patchy around my hairline,” she explained.

“I had been warned by my girlfriends that are mums and my hairdresser that this can happen. I didn’t believe it was a real thing until it happened to me.”

Pearce says it’s a “self-correcting condition”, as long as your levels of iron, iodine vitamin D and zinc are all where they should be to reset the phase of the hair.

For women who are affected, this can vary from 10 per cent to 60 per cent of the hair.

“If it’s really bad, I get them to do a little bit of laser therapy, six to 12 sessions. What that does is it dramatically slows down the hair loss.”

Bartel’s hair go-tos right now?

“I am a big fan of dry shampoo; it is my saviour being a new mum. I love Sebastian Drynamic ( $28.90) also when my hair isn’t dirty, as it works to give my hair some volume around my hairline, which is where I am losing lots of hair and this brand doesn’t leave my hair with white marks,” she says.

“I also use Kevin Murphy’s Powder Puff ( $38.95) as it gives my hair some more grit and makes it look thicker.”
