Sarah Jessica Parker is "thoughtful" about her wardrobe

She said: "I'm actually not a huge shopper. I mean I have more shoes now because I have a shoe collection, but even that I'm very thoughtful about. What do I really need? What can I borrow? What can I not live without? I've never, ever, ever, taken anything.

"In the case of 'Sex In The City', if we owned it then I owned it and it's in an archive, but if it was borrowed from a designer, or belonged to someone else, it always went back. Even when I borrow something for an important event, I always give everything back because I feel as if it's an honour system. It's like the library. You return the bag, you loved wearing it, you had custody over it for the night, and allow someone else the opportunity."

And the 51-year-old star also shared the secret behind her lustrous blonde locks.

She told Amazon's Style Code Live: "Here is what I really do. I wash my hair with Serge Normant products; that is the dead truth. I use his 'must haves' it's called Meta Silk in the black bottle with the conditioner. Then, I go to bed with a wet head and let the chips fall where they may.

"When my hair has been beaten up because I'm working, I use the Meta Morphosis Serge Normant, it's a miracle in a tub. That's what I find for me that really saved my hair. And if your hair doesn't look good when you wake up in the morning I don't know what to tell you. I'm sorry about that. Wet it and put it in a bun, just put it in a bun."
