The In Between Barrel: 2.5 inches sits between tight curl barrels and big wave barrels, right for crown lift with a soft wave on shoulder length layers Counted Rows: 48 boar bristle clusters and 32 nylon pins share the barrel, the boar smooths while the nylon grips through every roll Cork Under Pressure: When the dryer heats the barrel, the cork grip stays matte and easy to steer, no sweaty plastic feel Crown First Styling: Start at the crown for lift while hair is warmest, then work down and out, fine to medium hair responds fastest Keep The Count Working: Free trapped strands from the rows after use and store the brush dry, cork and wood both prefer it that way A round brush should feel like it disappears in your hand after the first few passes. The S2 uses a solid cork handle that weighs 2.5 oz — roughly 40% less than a beechwood handle of the same length — so your wrist stays fresh through a full blowout session. The barrel diameter sits at 2.5 inches; wide enough for shoulder-to-mid-back hair to wrap once with full heat contact. The bristle layout follows a deliberate sequence rather than a random mix. Nylon pins make first contact at the root to separate and lift each section. Boar bristles follow directly behind to smooth the cuticle flat and distribute natural oils from root to tip. This two-stage action means you finish each section in one pass instead of going back over it. Durability matters when you use a brush daily. Each bristle sits in a double-locked base with two anchor points holding it in place. The barrel houses 48 boar clusters and 32 nylon pins; all rated to hold position through months of heat styling without shedding onto your clothes or bathroom counter. You will get the most from this brush by working on fully dry hair at medium heat. Section your hair in strips about two fingers wide; wrap once around the barrel and hold under the dryer for eight to ten seconds per section. Fine to medium density hair typically holds the bend for six to eight hours. If your layers are shorter than your collarbone or longer than mid-back; a different barrel diameter will serve you better.
