Here are my curls almost 5 years after using henna exclusively to dye my grays, and honestly… it’s pretty + messy lol. My hair is naturally very dark brown, and my grays come in stark white (especially around my crown and the sides), so the contrast is loud. What I love is how henna hits those whites and turns them into this auburn-y tone, so you get this really pretty “split” effect along the strand where the color shifts. I usually re-henna every 3–4 months (so about 3–4 times a year tops), and I don’t just do my roots—I do my whole head. Over time the color has built up, and in the sun it gets super vibrant with that really pretty red all throughout, even though indoors it can look more subtle. I’ll be real: I don’t notice a ton of the “health benefits” other people talk about, but I do get a bit of strengthening, and it’s been a nice building block when my hair has been damaged in the past. The biggest takeaway? Henna lets me scratch that hair-color itch without the damage I get from commercial dyes (those tend to dry me out and cause breakage). Also: wear gloves. I didn’t last time, and my hands were orange for a week—so learn from my hot mess process.
