How Hairdressers Can Guarantee Reliable Grey Coverage and Vibrant Results

Achieving even, long-lasting grey coverage is one of the most common challenges for UK salons. Grey and resistant hair is often coarse and less porous, making it difficult for pigment to penetrate evenly. This can lead to patchy results, flat tones or faster fading, creating the risk of re-dos, extra product use and unhappy clients.

Andreia Professional Permanent Colours are designed specifically to deliver consistent, high-performance results on stubborn greys. Their conditioning, vegan formulas help pigment penetrate resistant strands while maintaining true-to-swatch tones.

• Up to 100% grey coverage

• Stable, fade-resistant pigments

• Reliable shade accuracy across appointments

• Conditioning formula with quinoa protein, prickly pear extract and avocado oil

• 0% Ammonia option for clients with sensitivities

• Creamy 1:1.5 mixing ratio for smooth, even application
  
  

Available through CM Hair & Beauty Supplies UK, Andreia gives salons a modern, trusted alternative to traditional grey coverage brands.

Grey coverage clients return every 4–6 weeks and expect the same shade every visit. Any inconsistency, uneven roots, weak coverage or unexpected tonal changes can undermine trust quickly. A predictable system like Andreia Professional helps salons deliver dependable results and strengthen long-term loyalty.

1. Prep properly

Apply to clean, dry hair. Ensure full saturation, especially around the hairline, where greys are most resistant.

2. Use the correct Andreia shade families

For stubborn greys, choose:

• N (Natural)

• IN (Intense Natural)

These can be mixed with fashion shades for customisation without losing coverage strength.

3. Respect full processing times

Allow full development for maximum pigment penetration. Cutting the time can result in weak or inconsistent coverage.

4. Keep detailed formula records

Note the shade, mix, timing and technique to ensure repeatable results every visit.

Salons using reliable colour systems like Andreia see:

• fewer re-dos and corrections

• stronger rebooking rates

• loyal grey-coverage clients

• increased efficiency and profitability

Consistent results protect your reputation and help grow long-term revenue.
