When you look back at your career, there are moments that are levels that you hit and you bounce off them.

When you work with great people, you learn - about film, about clothing, about life, about sex.

Suddenly it was cool to have your hair lank . . . It was a whole different way of looking at things, and it shook up the whole industry.

Beauty shouldn't be taken too seriously. Life is stressful enough! Hair should be creative and crazy.

I think now because of this whole social media thing, people obviously felt these things [about cultural appropriation] before, and they comment on everything.

Every culture to me - be it Asian, African, be it whatever - is a source of reference. I don't think I'm 'stealing' it or anything.

I must say, Gisele's [Bundhen] got some of the best hair I've ever touched.
