The TV star has gorgeous blonde highlights, but anyone with coloured hair will know it can be difficult to keep it looking shiny and healthy, let alone preventing the dreaded split ends.
During the show's beauty segment in September 2020, she told hairdresser Michael Douglas that she loves to use an Olaplex treatment at home – and that she's been thrilled with the results.

"It's [for] the highlights, and it's supposed to stop breakage... but definitely it helps with split ends and strengthening your hair," she said.
Shoppers can currently snap up the Olaplex 'Hair Perfector', which was featured on the show, for just £20.80 in Amazon's Spring sale – which will save you over £11.

We've also found the 'Intensive Bond Building Hair Treatment' that Ruth speaks so highly of for £26.
Both of Ruth's go-to products will come in handy in between hair appointments, which have been particularly difficult to come by following the outbreak of the COVID-19 pandemic.

The presenter has previously revealed that she loves using heated rollers to prep her hair for TV, and her favourites come from Cloud Nine.
Demonstrating how to use it on Instagram, she wrote: "It's called The O, by Cloud Nine, and you literally pop the roller in and it takes like three seconds and it beeps, and that means it's ready. Fantastic! And then you get the little clips with it as well."
