Rihanna shows off her colored hair by using some best hair products

Rihanna has been showing off her natural hair colour in a cheeky snap on Twitter.
She appears to be - gasp - topless, according to the Daily Mail, and is “working her natural locks in a sexy messy bun”. She is using some of the best hair products out there.

The picture is captioned “Where have you been all my life?” and shows her covering up her “modesty” with one arm and what looks like a blonde wig.

The singer had been seen in a blonde weave at the Grammy awards and has previously sported a bright red "do" but seems to have gone back to her natural colour again.

She’s been chopping and changing all year but we definitely prefer the natural look. Although, you can put some clothes on, Rihanna. We won’t mind.

The 24-year-old has also been getting involved with some worthy causes, and has backed the Invisible Children charity’s Kony 2012 campaign, says the Mail. 

In another tweet she wrote: “PLEASE go to www.Invisiblechildren.com Even if its 10 minutes... Trust me, you NEED to know about this! #1LOVE”.
