Shine on! London's top hairdressers share their secrets for glossy locks

A few summers ago, I tried to grow out my bob and failed miserably, because I didn't just want length, I wanted hair that was an event, a mane, hair that swished. For that, you need not only length but heft, and heft relies heavily on health.

I decided to embark on my growing endeavour for a second time with an eye on the health of my hair. Inch by inch, I turned my bob into shoulder-skimming, then modestly long hair. I kept going and currently it settles between the bottom of my shoulder blades. It's taken a full three years, but I'm nearly there now at the holy grail: hair that's long but also shiny, without frayed and damaged ends.

After extensive research, and many failures, these are the tips and products which really, really work. They will help you achieve your healthiest hair, whether you're after bum-skimming locks this summer or simply want to join the A-listers in the pursuit of 2025's biggest hair trend: an ultra-glossy look.
