MaterialsBoar bristle
Size2.75 inch
FinishAnti-Frizz, Detangling
  • Grip and Polish in Every Bristle:Each tuft pairs a firm nylon core for root tension and lift with pure boar bristle wrapped around it to smooth the cuticle — both work simultaneously in one contact, not in alternating passes
  • Smoothness That Holds After You Leave the Mirror:Hollow plastic concentrates dryer heat at one point; the solid wood core spreads it gradually — the cuticle closes without spiking, and the shape you set stays as the hair cools
  • Firm Grip, Clean Release:The nylon core holds each section under airflow without sliding; the boar outer releases without snagging — no scalp scraping, no tangling; where pure-boar brushes were too limp to hold a section, this one grips
  • 2.4 oz, Cork Handle That Stays Dry:Your arm holds this through a full blowout without fatigue; the textured cork grip stays non-slip as your hand warms — wrap one section, angle the dryer down the shaft, rotate once; the blowout your stylist charges for, done at home
  • What Arrives:One 2.75-inch round brush; 9.85 inches total length; 2.4 oz; solid wood barrel, natural cork handle — slight grain and texture variation between units is normal for these materials; bristle tuft spacing is consistent across units

Perfect! This is the brush my hairstylist uses so I decided to try one for myself. It’s fantastic! It’s big enough that it’s forgiving when you are trying to style your hair… It allows you to reach a bigger swath of hair. Plus, the handle is cork and lightweight. Love it!

I ordered this brush because quite frankly I've. I've never even seen a $45 hairbrush before so I was curious! I have to say I am pretty impressed! First off, I can't believe how late it is! I guess it's the cork handle, but the rest of it must be made with special material too because it is super light, which is nice when you're doing a blowout because your arms are up the whole time and of...

I ordered this Large Barrel Boar Bristle and Carbon Fiber Brush by TRENFI. This is the nicest barrel brush I have ever used. It is very lightweight and easy to hold onto with the wavy cork handle. My hand did not get tired, and my arm didn’t either as it’s so light and easy to maneuver. The bristles are a nice quality and allow good airflow when doing a blowout, this brush is just the right size...
