Curling Brush Donegal 20/34 (model 9020) — heated hair styling brush, dual-diameter 20/34 mm

Donegal 20/34 (model 9020) is a heated curling brush that combines brushing and thermal styling to create both tight curls and loose waves. The brush features two usable diameters—20 mm for tighter curls and 34 mm for larger waves—allowing flexible styling without switching tools. It is designed for medium to long hair, providing volume, shape and smoothing in one step while reducing styling time compared with separate brush and iron techniques.

Advantages

The dual-diameter barrel offers two styling options in a single tool, enabling quick transitions between small and large curls. Integrated bristles help detangle and guide hair evenly over the heated surface for more consistent results. The compact heated brush design shortens styling sessions and reduces the need for multiple hot tools. Materials and heat distribution are selected to provide effective shaping while helping maintain hair smoothness when used according to instructions.

Suitable for

• Creating tight curls on mid-length to long hair
• Forming soft, loose waves and beachy texture
• Adding volume at the roots and body through root-lift brushing
• Smoothing and styling damp-to-dry or dry hair as part of everyday routines

Key specifications

• Dual usable barrel diameters: approximately 20 mm and 34 mm for varied curl sizes
• Heated styling brush format combining bristles and a heated barrel
• Suitable for medium to long hair lengths
• Designed for forming curls, waves, adding volume and smoothing strands

How to use

Start with clean, towel-dried or dry hair depending on the desired result and the manufacturer’s safety instructions. Select the barrel diameter appropriate for the curl size you want. Section hair and wrap a small strand around the chosen heated section of the brush, hold for a few seconds until the curl sets, then release gently. For uniform waves, work in consistent sections and move from roots to ends, using the bristles to guide and smooth hair. Finish with a cool-down period for each curl and apply a light styling product if needed to set the shape.

Usage recommendations

Use a heat protectant on hair before styling to minimize thermal damage. Adjust technique and heat exposure according to hair thickness and condition: shorter contact time for fine or damaged hair, slightly longer for coarse hair. Allow the tool to reach operating temperature before use, and clean bristles and barrel after cooling according to care instructions to maintain performance and hygiene.
