INFINITIPRO The Knot Dr. Extra Small Oval Brush Attachment - Loose

In this review the INFINITIPRO The Knot Dr. Extra Small Oval Brush attachment proves a smart pick for anyone who wants quick, salon-style loose waves and painless detangling on short-to-medium hair. Paired with The Knot Dr. Hot Air Dryer brushes (models BC116 and BC120), the extra small oval head is designed specifically to shape curls and waves without fighting through knots, and the tourmaline ceramic finish focuses on reducing frizz and boosting shine for a polished finish.

Key Features

• Extra small oval design: The compact shape is tailored to create loose waves and curls on short-to-medium hair without overwhelming smaller sections.
• Compatible attachment: Snaps onto The Knot Dr. Hot Air Dryer brush collection (models BC116 and BC120) for seamless styling with an existing dryer brush.
• Painless detangling: 80 Flexalite nylon bristles with epoxy tips glide through knots to reduce pulling and make detangling gentler.
• Tourmaline ceramic surface: The finish helps reduce frizz and add shine so hair looks smooth and polished after styling.
• All-in-one styling: Designed to detangle, dry, and add shape in a single pass to save time during busy routines.

Who It's For

The brush attachment is best for people with short-to-medium length hair who want to add loose curls or waves while detangling during blow-dry styling. It suits those who already own or plan to use The Knot Dr. Hot Air Dryer brush models BC116 or BC120 and prefer a compact head for more control on shorter sections.

It is less ideal for those seeking tight ringlets, very thick long hair where a larger attachment may be faster, or users who do not have a compatible Knot Dr. dryer brush model. Buyers concerned about build feel or heat output should compare with other attachments before committing.
