Removable-Lining Hair Steamer Cap

This hair steamer cap combines functional textile engineering with rigorous electrical safety. Made from polyester fibre with a silver-coated inner lining, it reflects infrared heat back toward the scalp while resisting wear. At 380 g and 24 × 20 × 12 cm, it offers full coverage without strain during prolonged use. Thermal delivery is governed by an all-copper core thermostat and FR-4 flame-retardant board, delivering 55–65°C at the inner surface and 45–55°C where it contacts the scalp — a range validated for safe, effective keratin softening and product penetration. Heat intensity is selected via a tactile 10-position mechanical switch (level 8 recommended), where each step modifies power delivery rather than absolute temperature — enabling intuitive, reliable control. Three timer durations (20/30/45 min) map directly to hair service needs: 20 min for conditioners, 30 min for perms, 45 min for stubborn colour or coarse textures. Its anatomical curvature fits snugly without pressure, and the double-layer lining detaches completely for hand or machine washing — preserving hygiene and thermal efficiency. All electrical interfaces — plug, wiring, insulation, and fuse — comply with EU safety directives for Class II portable heating devices.
