Now we know what's under this chef's hat...

TV chef Nigella Lawson was spotted sporting a balding patch on top of her head yesterday as she went out to dinner with her husband.

Unusually the attention wasn’t on her cooking, but the lack of her usual thick brunette locks. As the picture shows, her hair looked straggly and lifeless as she arrived at a London restaurant.

The mother-of-two was dressed in a black fur trim coat with pale and make-up free skin as she arrived at the restaurant. In recent months she has lost 3 stone and slimmed from a size 16 to a 12, but thankfully doesn’t appear to have lost her curves all together. Apparently the chef has been exercising healthily with cardio training with Pilates and yoga.

Stress is said to be a cause of hair loss and this could have attributed to her hair loss after battling with her weight. However it maybe her hair just needs washing and brushing, as the 52-year-old has admitted in the past she doesn’t always brush or comb her hair!
