Frizz isn't just part of having curly hair. More often than not, it's caused by dryness, which lifts the hair cuticle and allows moisture in, creating that fluffy, frazzled look.
One of the biggest culprits is humidity. Here in the UK, our damp climate and near-constant drizzle make frizz a year-round battle, so it's safe to say I've put plenty of the best anti-frizz products to the test.
