Question: "I touched up my gray roots a week and a half ago and within a week they were already lighter than the rest of my hair. I already use color-treated shampoo and conditioner." -- Meghan L.
Answer: It sounds like "you're using the wrong color when doing the roots," says Johns. "Hair color should last three to six weeks or until the roots start to grow out. The ashier the color, the less gray coverage. The warmer the color, the better for covering grays," he advises. Also, be sure that you're using a permanent color that's intended for covering gray because semi-permanent color simply can't offer the same coverage. And, Johns says to continue using color-treated hair products in the shower because they will help keep color truer longer.
Question: "I have really dark hair and I'm considering coloring it red. What's the healthiest and most effective way to get the specific hue that I want? Should I go to a professional or buy a box at the drugstore?" -- Devran M.
Answer: "The best way to get the right hair color is to go to a professional," Johns says explaining that "If you pick the wrong red shade you (or we) may not be able to get it out or fix it." And, when it comes to choosing the hue, he advises, "When you go red, it should be a red that appears naturally, not a red that appears on a clown or a vegetable. Look for coppery, cinnamon, strawberry and auburn reds. Avoid aubergine, cherry, orange and pumpkin hues. If it doesn't appear in [natural hair color], it won't appear natural on you."

Question: "How can you extend the life of hair color while combating dandruff? I haven't found an anti-dandruff shampoo that doesn't cause my hair to fade." -- Jessica
Answer: Unfortunately, Johns says, "all anti-dandruff shampoos cause color fading, because they are like a medicine for your scalp." He continues, "the only way to extend the life of any hair color is to use the right [color-formulated] shampoo and conditioner." But, Johns recommends asking your doctor how long you need to use the anti-dandruff formula and to inquire whether there are other options for treating it.

Question: "Can I get highlights if I've already dyed my hair?" -- Patrice J.
Answer: Johns says that this is absolutely an acceptable practice. In fact, he says, "for most clients, I color them first, then I highlight them." His rationale for highlighting color-treated hair is that "it looks more natural."
