Vì sao tóc nhuộm cần chăm sóc khác

Hairdyeing process:

• Cuticle mở (NH3 + peroxide)
• Pigment chèn vào cortex
• Cuticle đóng lại nhưng never fully

Hậu quả:

• Hair shaft porous (xốp)
• Mất tự nhiên oil → khô
• Pigment thoát từng wash
• UV degrade pigment nhanh

Goal chăm sóc:

• Giữ pigment lâu (4-8 tuần)
• Repair protein structure
• Maintain shine
• Prevent breakage

Routine tuần
