She also says that keeping skin healthy and hair shiny is a tough job. You have to "keep at it", says the actress, even doling out tips for this purpose.
"Start with a good diet and healthy food. This is important for the body. You need to see that the products that you use are of the best quality...you have to make sure you are protecting your skin with a sun screen, using good shampoo and conditioner on your hair because that is something that we don't take seriously," said Katrina, who recently launched hair care range "6 Oil Nourish Hair care" by beauty brand L'Oréal Paris.
