Barker borrowed clippers from her mother and went on YouTube for tips. She said the only haircut she had given was "your typical No 1".
Although she was aiming for a fade, both she and Tarikopeka are happy with the haircut.
"I always revert to how to do certain things off Pinterest and YouTube, and let's just say doing hair is a totally different ball game to making cakes."
"An area that people will be touching up is the neck area, just use a trimmer to do that."
In terms of actual hair cuts, what do you say?
"Keep it simple. If it's a No 1 all over, it's happy days."
Monaghan said clippers should be the only tool used if you are going to cut someone's or your own hair at home. Monaghan was quick to banish the use of scissors.
"That's a whole different ball game."
Monaghan said you had to be careful because you didn't want to do irreversible damage to your hair.
"If they are waiting for us to cut it or if you're growing it out, just get it off the areas that are annoying. Just styling it so it's not irritable."
Monaghan said if the person cutting wasn't confident in doing so, just leave it.
"You don't have to impress anyone in isolation so leave it for us to take care of it.
"We're all eager to get back out there and look after our client base. We know there will be a heck of a lot more hair on each ... but looking forward to getting back in the shop."
