TRESemmé Beauty-Full Volume Pre-Wash Conditioner, $10.99.

Turns out beauty rules were meant to be broken! Especially now that this clever clogs product has hit the scene. It’s a pre-wash conditioner and yes – it is used BEFORE shampoo. It will protect fine hair without weighing it down, resulting in dreamy, full, voluminous locks. Its makers say the formula uses patented Fibre Polishing Actives (nope – no idea what they are) to bind to the cuticle to protect and soften the hair during washing, leaving it smooth and polished. Whatever – it definitely works. That much we do know.
