RITA HAZAN NEW YORK

If you ever colour your hair, you need to know about Rita Hazan New York. This Manhattan-based brand has made restoring damaged, dyed tresses its speciality. You don't have to head to NYC, though. With our selection of Rita Hazan hair products, you can enliven your locks from the comfort of your bathroom.

Whatever's causing your bad hair days, you'll find a solution with this brand. Are your highlights looking dry and lifeless? Pick up a balm, which is designed to leave a healthy gloss and restore manes to their salon-day best. Visible roots? There's a fix for those, too. The label's root concealer stick masks fast-growing greys and can be used to define eyebrows, too.

Then, of course, there's Weekly Remedy – the Rita Hazan hair treatment that InStyle magazine once called "the Wonder Twins for damaged hair". This two-step in-shower formula leaves locks feeling soft and frizz-free for up to 24 hours.

With products like this, it's not surprising that Rita has picked up so many celebrity fans. In fact, she's been styling the stars since the 1990s, when she worked at the famed Oribe salon on Fifth Avenue. Now, thanks to her eponymous haircare line, we can all enjoy her secrets, too. Hooray for that.
