We are are taken aback when celebrated Italian hairdresser Alessandro Calvio asks us, “Are you vegetarian?” just as we take a seat opposite him at the recently refurbished Taj Salon. We nod meekly, wondering how he figured it out. On cue, the light auburn-haired stylist points at tufts of frizzy hair playing peek-a-boo under our keratin-treated, limp, poker-straight tresses and smiles, “That’s due to iron deficiency. You need to include Vitamin C, B12 and iron in your diet.”
