Will this shade cover gray hair effectively?

IGORA ROYAL permanent colors are formulated to cover gray reliably when mixed and applied as instructed. Coverage success depends on the percentage of gray, previous color treatments, and correct developer strength; follow product directions for best outcomes.

• Suitable for partial to full gray coverage
• Use appropriate developer volume according to instructions
• Better results on uncolored or lightly processed hair
• Professional strand test recommended for heavily resistant gray

How should I apply and develop this permanent color creme?

Mix the IGORA ROYAL color cream with the manufacturer-recommended developer in the correct ratio, then apply to dry, unwashed hair for standard permanent coloring. Development time varies by desired result and hair condition; always perform an allergy test and follow timing guidelines on the packaging.

• Mix color cream and developer per label instructions
• Apply to dry, unwashed hair for conventional permanent coloring
• Monitor development time; rinse and condition after processing
• Conduct patch and strand tests before full application

What maintenance and aftercare keep the medium-brown tone vibrant?

After coloring, use color-safe shampoos and conditioners to extend vibrancy and reduce fading. Limiting heat styling, using UV protection products, and scheduling touch-ups at appropriate intervals will help maintain depth and shine.

• Use sulfate-free, color-protecting hair care products
• Avoid excessive heat and frequent washing to preserve color
• Apply UV-protectant sprays when spending time outdoors
• Plan regular root touch-ups to keep an even appearance
