回复：请教大家染发的后续问题：染发半年新长出的黑发和还没褪色的金发对比明显，在脑壳上呈一弧线

Buy Clairol's Herbal Essences Haircaolor #46 (Radiant Ruby) or 49 (beyond cherry). Since you already bleached your hair when you colored to Gold, these two colors will give you beautiful effects. Don't buy black one. It will look fake. If you don't like the dark red tone, you can buy the warmest dark brown. It will not only cover the golden color, but also give you a chocolate touch. Good Luck!
