Once summer finally arrives, those of us with naturally wavy hair relish the opportunity to down tools and let the warmer weather air-dry it. Katie Holmes is clearly in this camp, embodying the laidback mood by letting her natural texture loose in New York this week.

For Chanel's Annual Tribeca Film Festival Artists Dinner, Holmes – our forever style muse for myriad reasons – wore a white tee under a black cropped leather jacket with silky black high-waisted trousers (all by Chanel, of course).

Helping the monochromatic ensemble nod to the season, her voluminous tousled waves injected some summary nonchalance.

Just as it does when the actress styles it straight or with sleeker waves, Holmes' hair had a glassy shine, which is notoriously tricky to achieve with traditional 'beachy waves' as they are often enhanced with drying salt sprays.

Clearly, Holmes knows that this season a slightly more fashion alternative is a look coined "ocean waves", which is all about achieving a greaseless high-gloss with the texture.

To achieve the look apply a texture-enhancing product when wet, like the Larry King Wild and Unruly Curl Enhancer.

The hairdresser behind the product advises applying it "in small dots all over your palm and fingers, then gently massaging it in, trying not to disrupt the natural curl pattern".

To encourage volume at the root, flip your parting side-to-side every so often while it air-dries, being careful not to comb your fingers through the lengths.

Once dry, spritz in some shine with a product like the Charlotte Mensah Manketti Oil Finishing Mist (which will also help the hair retain moisture), and to further prevent frizz on muggy days, layer it with some Amika The Shield Anti-Humidity Spray.

We'd also make like Holmes and embrace the imperfection. Part playful, part grungy-glamour, it's the ideal look for a laidback summer.
