Demi Mono by Ellen Wille
Demi Mono by Ellen Wille: A Long, Wavy Bob with a Secure Fit
If you love length and movement but want a style that stays put, meet Demi Mono by Ellen Wille. It's a long, wavy bob with soft, loose waves that fall past the shoulders, a natural-looking monofilament top and an extended lace front, and it's built with Ellen Wille's new Secure Fit silicone-coated wefts.
Demi Mono launches on November 2, 2026, as one of three new Secure Fit styles in Ellen Wille's Hair Power Collection, alongside Elle Mono and Tess Mono Part.
A Long Bob with Real Movement
Demi's lengths are the longest of the three new styles: about 12 inches at the crown, 10.25 inches at the sides and 7.25 inches at the nape, with a 9.25-inch front that can be swept to the side or tucked behind the ears. The waves are loose and relaxed rather than tight, so the overall look is soft and touchable. It reads as effortless and feminine, the kind of long bob that looks just as right with jeans as it does dressed up.
What "Secure Fit" Means
The headline feature of this launch is Ellen Wille's new Secure Fit silicone coating on the wefts. Instead of relying on tension alone, the coated wefts grip gently where the cap meets your head, giving a reliable, non-slip hold that stays put through a busy day. It's designed for comfort as much as security, so the cap feels settled without feeling tight.
Mono Top and Extended Lace Front
Demi's monofilament top gives the look of natural scalp along the part, and because the hair is hand-tied there, you can change your part to suit the day. The extended lace front reaches a little further back than a standard lace front, so the hairline looks natural even when you wear the front pushed back or off the face. Wefted back and sides keep the cap light and breathable.
Heat Friendly Fiber
Demi Mono is made with Ellen Wille's Heat Friendly synthetic fiber. It holds its wave out of the box, and you can reshape it with low-heat tools when you want a smoother or more defined finish. At 4.7 oz, it's surprisingly light for a long style.

Caring for Demi Mono
Wash Demi Mono every 10 to 14 wears in cool water with a shampoo and conditioner made for synthetic fiber. Blot gently with a towel, never wring, and let it air dry on a wig stand so it keeps its shape. Detangle only when dry, working from the ends upward with a wide-tooth comb. Because the fiber is Heat Friendly, you can refresh the style with low-heat tools once it's completely dry; use a heat protectant made for synthetic fiber and keep the setting low. Our Wig Fiber Guide has the full details.
