『Work Sharing』Dyed Dark, Multiple DIY Dark Colors, Red Changed to Highlights Difficulty: ⭐️⭐️⭐️⭐️ Production Process: First, perform highlight coloring. The highlighted sections have a lot of residual pigment. After checking once, the bleach powder needs to be applied for 30 minutes, then each foil must be opened to reapply bleach powder and wait another 30 minutes to ensure the bleached sections start to fade, and then begin applying the base color. Since the original hair color is uneven, the choice of base color must be conservative. Therefore, I formulated a brown shade that provides coverage while maintaining balance. Because the highlights were not fully bleached, another round of bleaching is required after rinsing. The difficulty in this step lies in separating the highlights from the base color, ensuring that the light-colored sections do not come into contact with the base color, or else all previous efforts would be wasted. Due to the dark dye at the ends, the highlight coloring must be applied in a gradient manner, dividing the hair into three sections: roots, mid-lengths, and ends. Finally, the result shows no darker ends compared to the roots ✅ The gradient effect also enhances durability, making the regrown black hair less noticeable.
