The 47-year-old actress' famous locks are the envy of women around the world and the feathered cut she sported when playing Rachel Green in 'Friends' sparked a huge trend, but she insists she always has trouble with her tresses and is "always" working on ways to keep it looking good.

She said: "It's funny because my hair is, like, the bane of my life.

"I'm always thinking about how to tame it. I always think it's too dry, too frizzy, too kinky and it's, like, everyone loves it.

"The team and hairstylists - I owe it all to them. I can't take credit."

The 'Cake' star - who is married to Justin Theroux - credits her good looks to "confidence".

She said: "I'm pretty confident. It's just age and beauty. Beauty reflects confidence and keeps it going, you know? I guess you reach a point of peace with it all.

"My confidence has definitely built up [over the years]."

And Jennifer thinks she has learned how to take care of herself better as she has gotten older.

She added: "I think youth is wasted on the young. We don't do all the right things - like in your twenties not taking care of your skin or not treating it right or wearing enough sunscreen."

The 'Horrible Bosses' actress prefers to "play it safe" and stick with what suits her rather than follow fashion trends.

She told LOOK magazine: "When it comes to fails, you have to go back to the 90s.

"Now I play it safe and I don't like to follow trends because I just don't know what I'm doing."
