Henna isn't just for skin. Used correctly, natural henna is one of the oldest hair treatments there is — with real benefits and real limits.
What henna does for hair
- Colour: a translucent copper-to-red stain that layers with each use. It doesn't lighten hair; it deposits warmth.
- Strength: lawsone binds to keratin, which can make strands feel thicker and smoother over time.
- Scalp: many people find it soothing and anti-flake, though results vary.
A beginner-safe mix
- 100 g body-art or hair-grade pure henna powder (ingredient list should say Lawsonia inermis and nothing else)
- Warm water or brewed tea to a yoghurt-like paste
- 1 tbsp lemon juice or amla for dye release
- Optional: 1 tsp oil for slip
Rest 4–6 hours (or overnight in a cool place) before applying.
Step-by-step
- Section clean, dry hair.
- Apply the paste root to tip with gloves, coating each section fully.
- Cover with a cap and leave 2–4 hours.
- Rinse with water only until it runs clear; condition.
- Shampoo the next day — the colour keeps developing for 24–48 hours.
Honest limits
Henna is semi-permanent to permanent and hard to remove. It won't give ash, brown or black on its own. If you colour at a salon, tell your stylist you use henna. And skip any "instant" or "black" henna hair product — those are where the metallic-salt and synthetic-dye problems live.

Questions people ask
Does henna cover grey hair?
Pure henna stains grey hair a bright copper-red, not brown or black. For deeper tones you need to follow with indigo (a two-step process) — and never use 'compound' or pre-mixed 'black henna' hair products, which can contain metallic salts or synthetic dye.
How long should I leave henna on my hair?
2–4 hours for colour and conditioning. Longer isn't harmful but gives diminishing returns. Rinse with water only; shampoo the next day.
Can I henna over chemically coloured or bleached hair?
Do a strand test first. Pure henna is generally compatible, but results are unpredictable on bleached hair and the colour can shift. Avoid any product mixing henna with metallic salts before a future salon appointment.
