Best natural beard dyes for grey coverage

Start with BRUTUS Naturals Plant-Based Hair & Beard Color. It's the only line here that's genuinely plant-based and PPD-free, and it's made for men's hair and beards, so it covers grey without the harsh dye smell or sting. Pick the shade closest to your natural colour — Light Ash Brown is the safest all-rounder, Sandy Blonde if you're fairer.

Who the others suit:

• Copper or sandy blondes — BRUTUS's Copper Blonde and Sandy Blonde give a warmer, less flat result.
• Want the fastest, cheapest grey fix — the all-in-one black kit covers grey in about 7 minutes and lasts up to 5 weeks, but it isn't plant-based.
• Prefer a shampoo-style touch-up — the black beard colour shampoo is the easiest for quick top-ups between dyes.
• Want a bigger kit — the reusable kits at Nordstrom give up to 10 applications, though they're ammonia-free rather than plant-based.

Whatever you choose, patch-test first and expect plant-based colour to fade faster than chemical dye.
