This advanced electric hair regrowth brush from Hailicare is designed for body use and crafted from durable ABS, PC, and silicone materials. Free from harmful chemicals, it features a rechargeable 1400mAh lithium battery for cordless convenience. The device offers three massage modes—Wake-Up, Relaxation, and Sleep Prep—each paired with specific red, green, or blue LED lights to stimulate scalp microcirculation, relieve tension, and promote restorative sleep. Equipped with 72 rounded teeth, 8 micro-current comb teeth, and 6 elastic roller beads, it deeply massages the scalp while evenly dispensing nourishing liquids from its detachable 6ml reservoir. The 660nm red LED therapy aids follicle activation, enhances serum absorption, and balances scalp oil to combat hair loss. With adjustable EMS intensity levels and a compact ergonomic design measuring 21.2 x 8.5 x 5 cm, this professional tool supports healthier, thicker hair by improving scalp health and strengthening hair roots. The package includes the massage comb, Type-C charging cable, English manual, a storage bag, and packaging box for a complete user experience. Charging takes approximately 2.5 to 3 hours with up to 3.5 hours of use per charge. Note that the device cannot operate while charging.
