Tip #2: Opt For Semi- or Demipermanent Dyes
On the subject of ammonia, Schaudt provides another helpful tip: "Look for a semi- or demipermanent coverage," she told POPSUGAR. "These are typically ammonia-free, meaning the colour penetrates under the outer cuticle of your hair." And should things not go according to plan — whether you change your mind about the shade or miss a tiny spot — these formulas also give you a little more wiggle room, as they're not permanent.
