Miranda Kerr is ''obsessed'' with having clean hair.

The 30-year-old supermodel is extremely particular about making sure her shiny brown tresses look good at all times and has a strict shower regime, which includes using coconut oil and conditioner, to perfect her look.

She said: ''Hair-wise, I love using coconut oil as a treatment and apple cider vinegar for shininess. You put on a little bit in the shower as a rinse and then wash it out. It stinks a little, but then you use conditioner and the smell goes away. I'm obsessed with having clean hair.''

The Victoria's Secret beauty - who is married to 'Pirates of the Caribbean' actor Orlando Bloom - is equally passionate about staying healthy and even has plants in her home that ''purify'' the air.

She told website, Into The Gloss: ''Being healthy is the way that I am. I try to keep a healthy house. All the plants in my house are oxygen-producing and air-purifying plants.

''I have alkaline water filters in my kitchen sink and on my shower heads, so it's purified and alkaline. I learned about the benefits of alkaline in your body from studying nutrition, and there are many ways to do it - drinking alkaline water is one of them and drinking cold-pressed green juices, warm water with lemon and that sort of thing are also good.''
