  • LIGHTWEIGHT GRIP - NO TIRED ARMS:At four oz this brush is lighter than most wooden-handled round brushes; your arm doesn't give out before you finish a full blowout; the cork handle sits naturally in your palm without slipping; no adjusting grip between sections; the 2.75-inch barrel covers enough hair per pass that you're not repeating the same section three times to get lift
  • TWO BRISTLE TYPES - ONE PASS:Boar bristles distributed throughout the barrel pull your hair's natural oils from root to tip as you rotate and dry; the same oils that create shine just moved where they need to go; nylon pins reach beneath and grip at the root to create lift that stays; pure-boar brushes smooth but don't lift; pure-nylon brushes lift but can't distribute oil; this one does both in the same motion
  • WHAT TO KNOW BEFORE YOU BUY:The cork handle is a natural material; it grips well and reduces hand fatigue but should be stored dry between uses; avoid leaving it in a damp bathroom or submerging it in water; the wood joint weakens with repeated moisture exposure; in high-humidity environments some users notice increased static during blowout; a light finishing spray applied before drying reduces this significantly
  • BUILT FOR FINE AND THINNING HAIR - SHOULDER-LENGTH AND LONGER: The 2.75-inch barrel is sized for fine to medium hair that needs full contact to set volume; large enough to shape a section but not so large you lose tension control; wrap a medium section and roll toward the roots while directing heat down the shaft; hold for a few seconds before releasing; the volume sets from the inside out and not from product; not the right fit for hair shorter than chin-length
  • SPECIFICATIONS AND FIT GUIDE:Total length 9.05 inches; Barrel diameter 2.75 inches; Weight four oz; Works best for fine thinning or straight-to-wavy hair that is shoulder-length or longer; Not designed for very short hair; very curly or coily hair; or very coarse dense hair; those textures need different barrel sizes and bristle types; if this brush isn't the right fit for your hair type that mismatch is easier to identify before purchase than after

I love this brush. I was looking for a replacement for my previous one that I didn’t want to part with but the time had come. The boar head bristle is what I love to use. It is good for your hair, doesn’t pull on my hair and easy to style with. My hair length is just below my sholders

Just recd this brush. It’s everything I was hoping…..just like the Kevin Murphy brush my hair stylist uses that apparently is no longer available anymore. Bristles are soft yet it is firm to grab the hair amoothly.
