What it is: A smart hot brush for quick and effortless, three-dimensional volume that lifts your roots and creates body through your lengths. Hair Type: Straight, Wavy, Curly, and Coily Hair Texture: Fine, Medium, and Thick What Else You Need to Know: Give your hair the boost it deserves with twice the volume. Add lift at your roots and create body through your lengths for added shape, bounce, and fullness. The brush‘s heater technology spans the one and one-quarter inch barrel, responding to your hair‘s needs and ensuring a constant optimum temperature of 365°F to achieve healthy, long-lasting volume* with no extreme heat. Smooth, half-centimeter nylon bristles are developed at the optimum length to create gentle styling tension, allowing close contact with the roots for maximum lift and smooth gliding through hair for tangle-free styling. Great condition- there are 3 small bristles/spikes missing (image included above) but it doesn’t impact the performance at all, selling because I cut my hair and rarely use it.
