If you put your hair through the wars, scrimping on hair care is not a good idea. Bleaching, blow-drying, straightening, colouring, and using heated tools and lots of products all take their toll on your poor, overprocessed locks. But not all of us have £10 a pop to spend on conditioner, which is why this great bargain from Tresemmé gets two thumbs-up from us. The thick, rich cream is infused with keratin to help keep hair smooth and soft whether you blow dry or air dry, and it definitely improves the way hair feels. It's also safe to use on hair that's had a keratin treatment or Brazilian blow-dry. The bumper 500 mL bottles are usually £5, but grab one now from Superdrug for half price!
