- Memory-Flex™ tension bristle is ideal for quickly detangling thick or coarse hair. Comfortable ball point tips are gentle on hair and scalp. The iDetangle by Olivia Garden detangles quickly and gently on wet and dry hair. The Flexible Vented Head Design adjusts tension based on hair type. Extra large vents guarantees that the brush is always dry and free of moisture (unlike a cushion brush). Dual-Curve Shape perfectly hugs the scalp for incredible comfort and superior styling control. Every bristle is actively styling with each stroke. An added benefit is that it also provides a great scalp massage! More features include the ergonomic handle, unibody snag-free design, and special anti-slip coating. This is the perfect detangling brush.
