How to Use IROIRO blue hair dye the Right Way
Start with clean, dry hair unless the label says otherwise. Apply a small amount and add more only if needed. Focus on the areas with faded, dull color. Reapply every 4 to 6 weeks as color fades. Be consistent. Results build with routine use.
Mistakes to Avoid
The biggest mistake is using too much. Excess product weighs hair down and wastes money. Another mistake is skipping the patch test. Always test a new IROIRO blue hair dye on a small area first. Do not expect overnight miracles. Give any product at least a few weeks.
