What is the difference between ammonia-free and ammonia-based hair dye?

Ammonia opens the hair cuticle so the pigment can penetrate deeply — that is why permanent dyes with ammonia deliver the most stable results, especially on gray hair. However, if your hair is already damaged, dry, or you dye every 3-4 weeks, ammonia-free formulas are significantly gentler and reduce long-term stress on the hair fiber. Many modern ammonia-free dyes now cover even 50-70% gray hair quite effectively.

Which hair dye covers gray hair best?

Gray hair has a tougher cuticle that resists pigment, so not every dye can cover it properly. You need a permanent hair dye — ideally one labeled "100% gray coverage" — paired with the right developer strength (usually 20 vol). If your gray is under 30%, a semi-permanent dye may be enough for natural blending without a visible regrowth line.

When do I need a developer and which volume should I use?

Every permanent hair dye requires a developer (oxidant) to activate the color. If you are dyeing at the same level or darker, 10 vol is sufficient. For gray coverage or a 1-2 level change, go with 20 vol. For lifting 3+ levels you need 30 or 40 vol — but this puts more stress on the hair, so developer quality matters a lot here. When in doubt, always start with a lower volume.

How often should I retouch my hair color?

It depends on your growth rate and dye type. With permanent color, regrowth typically shows after 3-5 weeks — retouch only the roots, not the full length, to avoid over-processing the mids and ends. Semi-permanent color fades evenly over 6-8 washes and can be reapplied without stress. If you color frequently, always use a rebuilding mask between sessions to keep the hair strong.

What hair dye should I get if I have never colored my hair before?

If it is your first time, start with a semi-permanent dye close to your natural shade — it does not require a developer, does not alter the hair structure, and fades on its own if you are not happy with the result. This lets you test how a shade looks on you with zero risk. From there, if you want a more dramatic change or need gray coverage, you can move to permanent dye with confidence.

If you want a full shade change or complete gray coverage from root to tip, permanent hair dye delivers lasting color that holds up through washing. If you prefer something gentler — a tone refresh or a new shade without commitment — semi-permanent dye fades gradually over 6-8 washes. Plant-based dye suits those who want zero ammonia and natural ingredients, but it only darkens or enriches — it cannot lighten your hair.
