With office life on hold, who can be bothered to do a daily DIY blowdry right now? Not many, I’m sure.That’s why the timing couldn’t be better for the launch of a "between washes" range that promises you can have a lie-in AND still look presentable for the work video call.Tresemme’s new Day 2 range has a host of time-saving products but the one that’s really caught my attention is the unique Foaming Dry Shampoo, £4.99here.

It promises to clean your hair without a drop of water, leaving it fresh and clean with a single squirt. Unlike regular aerosol type products, with a powdery texture that often leaves brunette hair looking dusty, this is a clear mousse that promises to mop up grease when it’s applied into your roots.
