We know mornings are a mad dash to get out the door, but an extra minute spent in the shower can really kick up hair’s shine. ‘We often don’t rinse out shampoo and conditioner properly, and over time this can lead to dulling product build-up,’ says Trygstad. So spend at least 60 seconds under the showerhead while running fingers through hair, letting the water get to every layer. ‘Then look at the water as it’s streaming off your head and make sure it’s completely clear. If it’s cloudy, that means there are still some suds left,’ says Trygstad.
