Beyoncé Wears Low-Cut Dress, Shows Off Flowing Locks in Hair Care Ad

Beyoncé giving fans the secret to getting flowing locks just like her … pushing a new hair care product in a fabulous, low-cut outfit.

The singer-songwriter appeared in a clip for her brand CÉCRED — posted Sunday — holding a vial of amber liquid and then running her hands through her hair … shaking it around to show its bounce and volume.

She’s revealing quite a bit in the clip … showing off her chest in a low-cut outfit — before passing the bottle of CÉCRED to her mom, Tina Knowles, who passes it to the next person and so-on and so forth.

Ultimately, it ends up in an Ulta Beauty store … where, CÉCRED writes fans can go buy it now to get their hair lookin’ just like the Queen Bey.

Beyoncé’s still flying high from her numerous Grammy wins this year … including winning Album of the Year for the first time with her country debut, “Cowboy Carter.”

Bey’s hittin’ the road soon enough too … heading out on a world tour at the end of this month that will take her from L.A. and Chicago to Paris and London and more.

And, it looks like she’s developed a new favorite product to take on tour with her!
