Henna Is Not Just Another Box Dye
Henna hair dye shows up in nearly every professional's color conversation eventually, usually because a client asks about it after reading that it's "natural." That part is true: pure henna is a plant-based colorant, not a synthetic permanent dye built on PPD or ammonia. But natural doesn't mean simple, and it doesn't mean reversible. Reflection stocks the full Colora henna creme and powder range in Michigan, which makes it easy to get your hands on. Understanding what it actually does to hair comes first.
What Henna Actually Does to the Hair Shaft
Henna's color comes from lawsone, a dye molecule extracted from the Lawsonia inermis plant. Lawsone binds directly to keratin and coats the hair shaft, rather than opening the cuticle and depositing pigment inside it the way permanent color does. That's why henna behaves like a true stain. It sits on and in the outer layers of the hair, which is also why it fades through washing far more slowly than a semi-permanent gloss, and why it can't be lifted back out with a standard color remover once it's set.
Creme vs. Powder: Picking the Right Format
Colora's henna line comes in two formats, and the choice is mostly about workflow rather than the end result. The henna creme (Black, Burgundy, Mahogany, Brown, and Chestnut) is pre-mixed and ready to apply straight from the tube, which keeps timing predictable and consistent from one client to the next. The henna powder (Black, Ash Brown, Light Brown, and Natural) needs to be mixed with warm water or a mild acidic liquid into a paste, which takes more prep time but gives more control over consistency and intensity. Powder is also the format stylists reach for when blending a custom shade.
The Warning Every Stylist Needs to Give Before Applying It
This is the part of the henna conversation that actually matters at the chair, not just in a product review. Because henna coats the hair shaft instead of lifting it, it can interfere with chemical services that come after it. A relaxer, a perm, or even a permanent color line may not process evenly over henna-treated hair, and the result can turn out patchy, resistant, or more damaging than it would be on untreated hair. There's no reliable timeline for when henna "wears off enough" to make a chemical service safe again, since it depends on hair porosity, how many applications were done, and how the hair has been treated since. The safe approach is a strand test before committing to any chemical service on hair with henna history, every time, no matter how long ago it was applied.
Patch Test First, and Know What "Black Henna" Means
A patch test 48 hours before a full application is standard practice for any new color service, and it matters more with henna because allergic reactions, while uncommon with pure henna, can happen. It matters even more when a client mentions they've used "black henna" somewhere else. That term sometimes describes henna mixed with PPD or other synthetic additives to darken the result or speed up processing, and those additives carry a real risk of allergic reaction that pure henna does not. Colora's henna creme and powder are plant-based without that additive, but it's worth asking about a client's henna history before assuming every product they've used was the same thing.
Henna and Gray Coverage: Not the Same Job as Permanent Color
Henna on gray hair doesn't behave the way permanent color does on resistant gray. Because henna only deposits, it tends to tint white or gray strands a warm copper or orange tone rather than fully masking them in the target shade, since there's no existing pigment underneath for it to blend with. Clients looking for full, opaque gray coverage usually need a permanent color service instead, or need to go into a henna application with realistic expectations about the coppery cast gray hair will pick up. It's a good color to recommend for someone who wants warmth and shine with minimal commitment, not for someone trying to disappear every gray hair in one pass.
Getting a Clean, Even Result
Henna rewards patience more than speed. Section the hair the same way you would for any color application, apply from roots to ends with even saturation, and give it the processing time the product calls for rather than guessing. Once it's rinsed, skip shampoo for 24 to 48 hours if the client can manage it. Henna color continues to develop slightly after application, and an early wash can cut that short. Gloves throughout, since henna stains skin just as readily as it stains hair.
FAQ
Can henna lighten hair?
No. Henna is a deposit-only color that can add warmth, depth, or coverage over existing pigment, but it cannot lift melanin out of the hair the way bleach does. It works by staining the hair shaft, not by opening the cuticle to remove color.
How long does henna color actually last?
Henna fades gradually over many weeks rather than washing out in a handful of shampoos, since the lawsone molecule binds tightly to keratin. Expect it to hold noticeably longer than a typical semi-permanent gloss.
Can I color over henna with a regular permanent dye?
It's possible, but results are unpredictable since the existing henna stain changes how the hair takes new pigment. A strand test before a full application is the only reliable way to know how a specific head of henna-treated hair will respond.
