A reusable, 13g lightweight salon-grade aluminum foil hair treatment cap (also called a tin foil hair mask cap) offers two thickness options—standard (6C) and single-use (2C)—with a 27cm diameter, elastic band for a snug fit, and no electricity needed: its aluminum vacuum layer traps body heat and moisture for warm conditioning, ideal for daily use. Available in pink, blue, or black edge colors, it’s in stock for bulk wholesale (1440 pcs per 62×58×52CM carton, 22KG gross weight).
