Margaret Josephs is an open book when it comes to sharing her beauty secrets. From the trick behind her signature "power pigtails" (which you can see in the video above) to mother-daughter plastic surgery dates with Marge Sr., she has no problem dishing on it all and we absolutely love her for it. Recently, The Real Housewives of New Jersey designer took to Instagram to share another revealing detail about her signature look. 

For those who wonder whether or not Margaret is a natural blonde, the 'Wife has officially set the record straight. "If you didn’t know it I am a natural blonde though my roots are dirty," she wrote under a video of her microblading touch-up session at Wow Brow by Karin Beauty Bar. 

No wonder this hue looks so good on her — she was born to be a blonde!
