It can achieve different styles for all hair and beards, including curly, straightened, and fluffy, and keep your hair styling perfect and lasting for a whole day. Easy-to-use and safe anti-scalding design: The beard brush has both ceramic heating comb teeth and silicone comb teeth. The silicone comb teeth are slightly longer and soft, which can protect your scalp from burns. The handle design of the beard brush is ergonomic. The flexible 360° rotatable power cord makes it easier to manipulate and effectively prevents knotting during use. Dual temperature mode: This product heats up quickly, five to ten times faster than traditional straight hair clips. Warm-up in 15 seconds. There are two settings for temperature during use, Choose the 180°C(356°F) for Coarse and Wavy Hair; Choose the 200°C(392°F) for Thick and Curly Hair. Universal voltage: This product generally uses a 110-240v voltage power supply, you can take it to travel anywhere, very convenient. Gift-giving would also be a good choice. However, please note that you should wait for the product to cool down before storing it to avoid scalding you and the case. The correct way to use it: Please keep your hair dry and neat before using it. Turn it on and choose the temperature by pushing the on/off button. In the process of using, one hand pulls hair and comb hair with a straightener. If you want to keep hair straight last longer, please wash hair cleanly and use hairspray before hair straightening.
