When viewers were introduced to Domenica on the latest season, she had slightly longer caramel locks.
Domenica's beauty transformation comes a month after she took her fans on a trip down memory lane to her teenage years.

"Never getting rid of the gap," she captioned the snap, adding: "Who had this headband?!" referring to a bowtie headband that was made hugely popular by Supre in the mid-2000s.
