Learn how to use a 65mm round brush, like the Kent LBR2 with pure black bristle, to add volume and shine to your hair. Step-by-step blow-dry guide.

Quick Answer

For blow-drying volume and shine, use a 65mm round brush like the Kent LBR2. Its pure black bristle smooth the cuticle and distribute natural oils, while the barrel size lifts roots for body.

Why Barrel Size Matters for Volume

A 65mm (2.5-inch) barrel is a mid-large size that wraps medium to long hair in wide sections. This creates a smooth, bouncy C-curve rather than tight curls, so the hair lifts at the roots without kinking. Smaller barrels (under 40mm) produce tighter curls but less root volume.

Pure Bristle vs. Mixed or Nylon Bristles

Pure black natural bristle, like the Kent LBR2 uses, is flexible and grips the hair shaft gently. It polishes the cuticle for shine and carries natural oils from root to tip. Nylon bristles detangle faster but can pull fine hair and don't distribute oil as well. A pure-bristle brush is ideal for shine, though it may take slightly longer to blow-dry very wet, thick hair.

How to Blow-Dry with a 65mm Round Brush for Volume and Shine

1. Start with Damp, Sectioned Hair: Towel-dry hair until it is damp, not dripping. Divide hair into 4-5 horizontal sections (nape, mid, crown, top). Clip each section out of the way. Checkpoint: If hair is too wet, the brush will drag and cause frizz. Blot with a microfiber towel first.
2. Position the Brush at the Roots: Take a 2-inch wide section. Place the 65mm brush under the section, close to the scalp, and angle it slightly upward. Aim the blow-dryer nozzle at the roots from above. Common mistake: Holding the brush flat against the head flattens the roots. Keep it angled to lift.
3. Dry the Roots First, Then the Mid-Lengths: With the nozzle on medium heat, dry the root area for 5-7 seconds. Then roll the brush slowly down the section, following the dryer nozzle. Keep tension on the hair as you roll. Checkpoint: If the brush slips or hair wraps unevenly, reduce section size to 1.5 inches.
4. Finish with a Cool Shot for Shine: Once the section is 90% dry, switch the dryer to cool air. Hold the brush in place for 3-4 seconds, then release the hair. This sets the cuticle for extra shine. Common mistake: Skipping the cool shot leaves the cuticle open, reducing shine and causing frizz later.
5. Repeat and Let Hair Cool Completely: Work through all sections in the same order. After the last section, let hair cool for 2-3 minutes before brushing or styling. This locks in volume. Checkpoint: Rushing to style warm hair will flatten the lift. Wait until it's fully cool.
