The brand’s hero product is the Bigoodino Headband: a heatless, long-lasting wave in just 20 minutes. It works on dry, brushed hair. You wrap your strands around the headband and wear it for an hour for natural waves, or overnight for more defined waves that can last two or three days. It suits every hair type, straight or curly, short or long. For longer hair, the 2-Headband Combo (one per side) is ideal, while the KIT brings together the Headband, Clip and Comb, so you have everything you need in a single purchase. The Biphasic Serum, sprayed on the hair before styling, helps the wave last longer, especially on fine hair. For those who sleep in their waves, there are satin pillowcases and a sleep mask. Every purchase is backed by a 30-day money-back guarantee.
