A till containing cash and boxes of hair dye were stolen from an Ilkeston salon over the weekend.
Thieves forced their way through a back window at Finesse on South Street and escaped the same way after grabbing the haul.
Staff discovered the break-in and reported it to police on Monday morning.
Officers say it happened some time between 4pm on Sunday and 9.30am yesterday.
Anyone who saw anything suspicious or has been offered Wella products to buy can call police on 101.
