Scalp Massage Systems for Hair Growth
42 patents in this list
Updated:
Mechanical scalp massage systems must navigate the complex anatomy of the scalp, where the galea aponeurotica and underlying muscles form a thin, interconnected layer requiring precise stimulation. Current devices typically deliver forces between 0.5-2.0 N across contact areas of 1-4 cm², but achieving uniform pressure distribution while accommodating varying head geometries remains challenging.
The fundamental engineering challenge lies in replicating the nuanced biomechanics of manual massage—combining sliding, compression, and vibrational forces—while ensuring user comfort and safety across different scalp conditions.
This page brings together solutions from recent research—including synchronized multi-element massage heads, contour-adaptive protrusion systems, eccentric wheel-driven reciprocating mechanisms, and independently controlled vibration assemblies. These and other approaches focus on delivering consistent stimulation while accommodating individual user differences in scalp sensitivity and head shape.
1. Scalp Massage Device with Horizontally Vibrating Elastic Gripping Heads
Sotsu Medical Co., Ltd., SOTSU MEDICAL CO LTD, 2023
Scalp massage device with horizontal scalp gripping heads that provides deep relaxation to the scalp muscles and fascia. The device has a base with a drive source, and the massage heads attach to the base. The massage heads have elastic fingers that grip and horizontally vibrate along the scalp. This stimulates and relaxes the thin scalp muscles and fascia. The horizontal gripping motion allows deep massage of the scalp muscles and fascia, which are thin and interconnected with other body areas.
2. Head Massager with Rotating Synchronous Mechanism for Sliding and Swinging Massage Components
SHENZHEN BREO TECHNOLOGY CO LTD, Shenzhen Breo Technology Co., Ltd., 2023
A massage mechanism and head massager that provides a more effective and comfortable scalp massage experience by mimicking the humanoid grasping and pinching action. The massage mechanism has a rotating synchronous part that simultaneously drives multiple sliding and swinging massage components. This allows the massage parts to slide, swing, and oscillate at varying speeds. It creates a humanoid grasping and pinching motion that relieves scalp tension and promotes blood circulation. The periodic reversing rotation of the synchronous part opens and closes the massage components in a repeating cycle.
3. Scalp Care Device with Contour-Adaptive In-and-Out Massaging Protrusions and Rotatable Support Mechanism
