Common bristle materials include ABS (plastic), nylon, boar hair, and mixed combinations (for example, nylon plus boar or mixed boar bristles).
Features that add volume include listings that specify a volumizing purpose, S-shaped teeth that create air gaps between strands, and heated or oval brush designs that smooth, shape, and add lift.
Results list metal barrels and heat-retaining coatings—examples include ceramic-coated rims and copper-coated round barrels—chosen for better heat transfer and faster styling.
Product details describe boar bristles as helping distribute natural scalp oils along the hair shaft and adding shine; reviews also credit boar bristle brushes with conditioning effects and improved oil distribution.
Product care is listed as “Spot or Wipe Clean.” The details also note the tool is intended for use on dry hair and may include safety features such as auto shut-off.
