Liquid hair: Zendaya’s flaunting it, Dua Lipa is doing it and loads of our favourite celebrities are donning the hair trend on red carpets. This ultra-smooth, sleek and almost fluid like hairstyle is the best way to carry your mane, especially if you’re looking for something manageable. To get that glossy, frizz free finish, apply a shine boosting serum from mid lengths to the ends of your hair before you iron it and flatten the top section of your hair with your palms gently.
