We're used to seeing Gabrielle Union all glammed up, but the 41-year-old actress recently let her hair down (literally!) when she posed for the camera au naturel, showing off her real "thick" and "healthy" locks for her 1.6 million Instagram followers. And guess what? She still looks amazing. 

"Ladies... You can achieve hair growth... With a weave! This is allllll mine, no clips, no extensions, hadn't even been pressed," the recently-engaged gal posted early this month. "And it got this healthy thick length from responsibly wearing weaves. #weaveandflowletitgrow." 

Not only does Gabrielle practice good hair care maintenance, but she also follows a strict diet and workout regimen, which helps keep her locks looking good. "I try to drink a gallon of water a day and it’s made a huge difference in my hair, skin, and nails," she told Essence in a 2012 interview.

Another tip for long and luscious locks, courtesy of the future Mrs. Dwyane Wade? Ditch the processed food. "It’s fast, but it’s not always the best thing for your body, your skin and your hair," she told About.com.

This isn't the first time the Being Mary Jane actress has rocked her God-given 'do. Back in 2011 she tweeted a picture with some more hair care tips:

"I wear weaves for my job to protect my own hair from heat and product buildup. I don't leave weaves in longer than six weeks, and I use quality hair. I haven't had a relaxer in over ten years! Natural hair is great and weaves can give you plenty of easy options. [Here, my stylist] used a blow dryer and flat iron on low around my edges."

We must say we're impressed with Gabrielle's health and beauty routine — and we're even more impressed how amazing she looks at 41!
