A mother has been documenting her baby's 'crazy' hair after she was born with her hair sticking completely up - resulting in strangers stopping her in the street.

Aliyah Lewis' 10-week-old baby, Arla, was born with a unique hair style, with her hair growing outwards in every direction.

20-year-old Aliyah said Arla's locks started growing out after her first bath and have continued to grow since.

Posting videos of Arla on TikTok, Aliyah said the quirky hairstyle has led some people to question if she has uncontrollable hair syndrome or a cows protein allergy.

The stay-at-home mum from Barry Island, Wales, said Arla's hair 'just doesn't stay down'.

She said: "It just doesn't stay down at all.

"I've tried brushing it and nothing happens.

"When it’s wet it goes down and then 2 minutes after the bath it goes straight back up.

"She could be wearing a hat for 30 minutes, you take it off and within a couple of minutes it's back up again.

"I don't think it's uncontrollable hair syndrome as that usually tends to be white, almost silvery hair, and Arla's isn't like that."

"Some people on TikTok have said it can be a cows milk allergy, but she doesn’t have any other symptoms of that allergy."

Arla's 'soft and fluffy' hair is not only appreciated by her parents, with friends and family as well as strangers all taking an interest.

"Random people have stopped me when I'm out and about, commenting on her hair.

"Everyone in the family think’s it’s crazy."

Aliyah, and her partner Adam, 22, are secretly hoping that Arla's hair stays the way it is for years to come.

She said: "To be honest, I quite like it.

"It's almost like her own little personality.

"So I hope it stays that way."

Adam said: "I think it's really funny. Pretty nuts, isn't it?!"
