Beyoncé's colourist has to do extensive "homework" before highlighting her hair.

Rita Hazan - who started as a hair dresser aged 17 - has admitted the position of the 'Lemonade' hitmaker's highlights are "very important" and she has to attend the singer's concerts to carefully study her hair and how it falls to know exactly where to place the dye.
Speaking about Beyoncé's intense beauty regime, Rita said: "With Beyoncé, the placement of her highlights is very important to me, so I do homework. I go to her concerts and I watch how her hair moves in the wind!
"But it's important that your hair colour be customized to you. Look for images of women who has the same skin tone and eye colour as you so that you're confident the colour will work.
And the stylist has revealed the mother of two - who has four-year-old daughter Blue Ivy with her husband Jay Z - "constantly" changes her style.
She explained: "Beyoncé likes to change it up constantly! But if you're not on-stage like her, you can go a bit longer between touch-ups.
"[But] I see every one of my clients once a month, if not more ... But the truth is, your colour is going to fade. That's why I created a gloss that you can use two to four times a week before conditioning to help with vibrancy. You should have beautiful hair all the time."
And Rita - who boasts a large celebrity clientele including Mariah Carey, Jessica Simpson and Jennifer Lopez - has revealed she was the stylist behind the 'Heartbreaker' hitmaker's "dramatic change", which saw her change her brunette locks to a blonder shade for the cover of her 'Butterfly' album.
She said: "Mariah's hair was brown and I took her a lot blonder than she'd ever been. It was a dramatic change.
"I mean I grew up listening to Mariah Carey, so I was like, 'This is the coolest thing,' but [I had to] leave that at the door and do my job."
