Gray hair can appear gracefully as we age, but many of us still long for a polished, youthful look. Covering gray hair effectively is about restoring dimension, shine and softness without damaging your hair. Tressa Hair Color Gray Coverage has become a professional favorite because it delivers natural‑looking results while caring for the hair.
In this expert guide you’ll learn why Tressa’s Colourage line stands out, which shades work best on gray hair and how to apply them for salon‑worthy results at home.
Why Gray Coverage Matters in Hair Color
A Modern Salon survey found that nearly half of people color their hair specifically to address gray strands. Gray hair behaves differently than pigmented hair: coarse gray strands can be stubborn while fine grays absorb color faster. Understanding these differences helps you select the right product and technique. A quality professional hair color like Tressa Colourage respects hair texture and delivers long‑lasting, luminous color without harshness.

Why Tressa Is Recommended for Gray Coverage
Fade‑Resistant Formula That Locks Color
One of the biggest frustrations when coloring gray hair is how quickly the color fades. Tressa addresses this with its dye coupling technology, which creates strong molecular links that resist washing out. The result is longer‑lasting color that stays true between touch‑ups.
Stylists also note that Colourage mixes at a 1:1 ratio with developer; this double‑pigment system means you can achieve intense coverage without needing extra pigment additives
Multi‑Dimensional, Translucent Tones for a Natural Look
Gray hair often appears flat when covered by opaque dyes. Colourage uses translucent pigments that allow light to reflect off the hair, creating a natural, multi‑dimensional finish. This effect mimics the way natural hair has lighter and darker strands, so the color doesn’t look “solid” or artificial. If you’ve tried other colors that left your hair dull or monotone, you’ll appreciate the healthy shine and dimension of Colourage.
Oleic Acid for Hair Shine and Condition
An oleic acid base conditions hair while the color processes, preventing the natural oils from being stripped Oleic acid, a fatty acid derived from olive oil, helps smooth the cuticle and adds softness. Combined with the low ammonia content, it keeps hair shiny and manageable after coloring, even on coarse or textured gray strands.
User and Professional Testimonials on Gray Coverage
Stylists consistently report that Colourage is easy to formulate and delivers “what you see is what you get” results. Because the gel mixes quickly and stays consistent, there’s less guesswork. Professionals also appreciate that they can mix any shade 1:1 with developer to create a double‑pigment formula for stubborn grays. This flexibility means you don’t need multiple tubes of NN (double neutral) colors on hand, one tube and the right ratio will do. Users describe Colourage color as shiny, natural and long‑lasting.

Best Tressa Hair Color Shades for Gray Coverage
Tressa offers a wide range of shades. Here are some top picks for gray coverage, along with guidance on choosing the right shade for your hair type and skin tone:
6NA Natural Ash Brown
This Tressa hair color shade provides balanced coverage for medium to dark brunettes. The neutral ash base helps counteract brassiness while giving natural dimension. It’s ideal if you have predominantly gray temples or salt‑and‑pepper hair because it blends grays seamlessly without turning them too warm. Pair it with a 20‑volume developer for optimum deposit.
8AA Medium Cool Ash Blonde
If you prefer a lighter blonde with cool undertones, 8AA is a strong choice. The double ash (AA) tone neutralizes yellow in gray hair, resulting in a soft, smoky blonde. This shade suits lighter complexions and pairs well with cooler makeup palettes. Because ash tones absorb quickly on gray hair, check your processing time and always perform a strand test.
10B Lightest Blush Beige
For those who love a radiant, warm finish, 10B provides a soft blush beige that warms up gray hair without appearing brassy. It’s perfect for those with warm skin undertones and lighter natural color. The beige tone adds a hint of warmth that flatters mature complexions and gives hair a sun‑kissed glow.
Other Noteworthy Shades
- 5NN Natural Brown: Excellent for coarse gray hair that needs deeper deposit. Mix 1:1 with developer to create a rich, double‑pigmented result.
- 7Aa Dark Cool Ash Blonde: A darker ash blonde with cool undertones for blending moderate gray levels in light brown to dark blonde hair.
- 4R Auburn Red: If you love vibrant reds, this shade delivers a rich auburn with translucent dimension. Warm reds can brighten dull gray hair and complement rosy skin tones.
How to Choose the Right Shade
When selecting your shade, consider both your natural base color and skin undertone. A general rule: cool skin undertones (pink or blue) pair well with ash or neutral tones, while warm undertones (yellow or golden) look great with warm or beige hues. For high percentages of gray (75 percent or more), choose a shade with extra pigment and mix 1:1 with developer for better coverage

Application Tips for Optimal Gray Coverage with Tressa
Preparation and Mixing Guidance
Proper preparation ensures even coverage. Follow these steps:
- Assess hair texture and gray percentage: Coarse gray hair may require a stronger formula or longer processing time, while fine gray hair absorbs color quickly. Determine whether you need a permanent or semi‑permanent formula based on the amount of gray.
- Use a neutral (N or NN) series when in doubt: Neutral shades contain red, yellow and blue pigments, which help counteract unwanted tones and deposit color evenly on non‑pigmented hair.
- Mix color and developer thoroughly: Colourage’s gel consistency mixes easily. Use a 1:1 ratio with 20‑volume developer for maximum gray coverage, adjusting developer strength for lighter or darker results. Mix only what you need to avoid waste.
- Protect the hairline: Gray hair around the face can be more resistant or more porous. Soften resistant areas by applying 20‑volume developers around the hairline before applying color. For porous areas, apply color last or use a lower developer.
Application Techniques to Ensure Even Coverage
- Section hair into small subsections: Apply color to thin, even sections to ensure all strands are saturated. Work systematically from back to front, saving the hairline for last if it’s porous.
- Start where gray is most stubborn: Apply the mixture to areas with the highest gray percentage first. This ensures maximum processing time on stubborn sections.
- Use a brush and bowl or applicator bottle: Because of the gel consistency, Colourage works well with either method. For precise placement, a brush allows better control; bottles speed up full‑head applications.
Timing and Aftercare Advice
Processing time varies by shade and hair type, but generally 30–45 minutes will give full deposit. Check the strand after 30 minutes to see if additional time is needed. Once complete, rinse with cool water until water runs clear, then shampoo with a color‑safe formula and condition. Moisturizing shampoos and treatments help maintain shine and extend color life. If you have a lot of grays, plan a root touch‑up every 4–6 weeks to keep regrowth under control.
