A full set of Olaplex shampoo, conditioner, and various treatments. Used it for a week, made my hair feel v weird.
The obligatory juicer - DH bought it, juiced everything possible for 2 days, hasn’t touched it since.
A bread maker that wastes space in my kitchen and only gets used a few times a year when DD is home from uni. However, she’s coeliac and hates most of the bread you buy so I keep it to make her bread when she’s home.
I do have an air fryer, which gets used constantly. It’s got lots of different settings on it so I rarely use the oven now.
