UMIGA 38mm thermal brush for curls

Key points

If you want an easier way to create curls and root volume, UMIGA’s 38mm Thermal Brush is built for styling with less fuss. It can work as a smoothing thermal brush, a round heated brush for curl shaping, or a regular comb for everyday detangling. The main idea is simple, you wrap hair around the round heated barrel using elongated bristles that are designed to help prevent tangling, while still guiding the hair into shape. 🙂

The heated part uses PTC technology and releases negative ions, which the manufacturer says helps reduce heat damage and frizz. There is also a tourmaline heating element intended to support more even heat through the hair. That combination is designed to leave hair smoother and more manageable, not just temporarily curled. You get more control too, because there are 2 temperature settings that you can match to your hair thickness and texture.

One detail worth noting is that this is not a hot air brush, it does not generate airflow, and it does not rotate. That means it behaves more like a heated styling brush that you guide through your hair rather than an automatic rotating tool. If you prefer a hands on brushing method where you can keep hold of the direction, this style is straightforward to work with.

Benefits

UMIGA positions this thermal brush as a 3 in 1 tool, so you can switch between smoothing, combing, and curling without bringing separate devices to your routine. The round brush design uses elongated heated bristles that help wrap hair around the shaft while aiming to avoid snags. For many people, that translates to a quicker styling flow because you can comb and curl in one movement, rather than adding extra steps with clips and separate tools. ✅

A big selling point is the ion and tourmaline approach. The heated comb releases negative ions to help reduce frizz and heat damage, according to the manufacturer, and the tourmaline part is described as supporting even heat distribution. That matters because uneven heat can leave hair feeling rough or overly dry in some areas. Here, the goal is a more consistent result, with hair left smoother and healthier looking after styling.

The tooth shape and bristle setup also aim to make it easier to glide through hair. It features wide, cool teeth, plus anti tangle bristles designed to grip and move through hair more smoothly. If you regularly battle with tangling during styling, or if you just want less snagging around the roots, that design intent is directly relevant to day to day use.

The temperature settings cover more than one hair type. Low is intended for delicate or fine hair, while higher heat is for thicker or stronger hair textures, based on the manufacturer guidance. It’s also designed around creating curls and volume, especially root volume, where you want lift without excessive styling steps. With the 2 settings, you can keep the method consistent while adjusting the heat to suit your current hair.

For travel convenience, the dual voltage from 100V to 240V is a useful practical feature. It is described as being suitable for globetrotting, so you can use it in more places without swapping as often. Just remember the limitation from the manufacturer, it is not an air curler and does not produce airflow, and the brush does not rotate. That keeps it firmly in the manual heated brushing category, so you’ll want to guide the hair the way you would with a normal curling brush.

Who it’s for

It’s a good fit if you like shaping curls and creating root volume using a heated round brush, and you want a tool that can also detangle and smooth. It makes sense if you prefer controlling the direction and hold while styling, rather than relying on rotating mechanisms or airflow. You may want to skip it if you specifically want a hot air curler with airflow, because this one does not generate airflow and does not rotate. Better avoided if you need a device with more temperature options, since this model offers 2 settings only.
