| The question | Can a home test answer it? | Which test |
|---|---|---|
| Is it human hair, not synthetic? | Yes | Burn test |
| Has it been coloured, permed or stripped? | Mostly | Bleach strand test, wash and air-dry, smell |
| Is the texture its own or steam-set? | Mostly, over several washes | Wash and air-dry |
| Are the cuticles intact and aligned? | Mostly | Cuticle slip test, tangle test |
| Is the weft well made? | Yes | Weft inspection, shed test |
| Did it come from one donor? | No | The vendor's written statement |
| Which country did it grow in? | No | The vendor's written statement |
What "raw" has to mean before you test it
You can only test hair against a definition, and the trade does not share one. Some sellers use the word for any undyed hair, steam-waved or not, or for mixed-donor hair. At Suvita, raw means hair from a single donor that has not been chemically processed: no colour, no perm, no steam-set pattern, washed and conditioned only. That is the definition this page tests against. The raw vs virgin vs Remy guide sets it beside virgin and Remy.
The definition has two halves, and they need different evidence. "Unprocessed" leaves marks on the hair that a buyer can check. "Single donor" does not. A bundle from one donor and a bundle matched from two or three unprocessed donors can pass every test below in the same way. Be wary of anyone, us included, who says a strand test proves donor count.
The testing protocol, step by step
Test one bundle and keep a second untouched as a reference. Cut test strands at the weft, close to the stitching, so you do not spoil the length.
- Inspect the weft dry. Stitching, weft edge, shade from root to tip, the taper of the ends. Weigh it: a bundle is 100 g. Smell it.
- Slip test. Feel the cuticle direction on a few strands before anything is washed off.
- Burn a few strands to rule out synthetic fibre.
- Wash three times with plain shampoo and no conditioner, smelling it wet, and let it air-dry without heat or product.
- Tangle and shed test on the dry, washed bundle.
- Bleach a strand if you colour hair, last, because it destroys the strand.
Repeat the slip test after washing: if the hair only felt right while coated, you will know.
What each test can and cannot prove
| Test | How | What it can show | What it cannot prove |
|---|---|---|---|
| Burn test | Hold a few strands cut from the weft end over a flame, away from the bundle | Human hair burns slowly, smells of burnt hair and leaves a crumbly ash; synthetic fibre melts into a hard bead | Anything about processing, donors or origin. Animal hair burns much like human hair |
| Float or water test | Drop strands into a glass of water | Very little | It is widely repeated but unreliable: coatings, oils and trapped air change how strands sit. We do not use it |
| Bleach strand test | Lift a small strand with lightener and watch it through the stages | Unprocessed hair lifts evenly; dyed hair lifts patchily or in bands; stripped hair turns gummy or snaps | Donor count. A clean lift fits raw, virgin or unprocessed Remy alike |
| Wash and air-dry | Wash with plain shampoo, no conditioner, three times, and let it dry untouched | Silicone coatings wash out and show the real feel; steam-set patterns loosen while a natural texture returns | Donor count or origin. One wash is not enough to judge |
| Cuticle slip test | Pinch strands and slide your fingers tip to root, then root to tip | Aligned cuticles drag one way and slide the other; hair that feels the same both ways may have had its cuticle stripped | Raw versus Remy: Remy hair is cuticle-aligned too |
| Tangle and shed test | After washing, finger-comb and brush gently from the ends up; run fingers along the weft | Matting suggests mixed-direction or damaged cuticles; heavy shedding at the weft points to the stitching | Donor count. Shedding is about weft construction more than the hair itself |
| Smell | Smell the bundle dry and again when wet | A strong chemical, sour or heavily perfumed smell suggests processing, or something being covered up | Very little on its own. Perfume can mask, and washed hair can smell neutral either way |
| Weft inspection | Look at the stitching, the weft edge, the ends and the shade from root to tip | Even stitching and a secure weft; one head's natural variation in shade and taper; perfectly uniform colour on a 'raw' bundle usually means colouring | That ends were drawn by hand rather than processed, or how many donors went in |
Three of these tests do most of the work. The wash and air-dry test removes the finish that makes processed hair feel good on arrival. The bleach strand test shows past colour or stripping that washing cannot. The cuticle slip test, repeated after washing, shows whether the cuticle survived. The float test is not worth the water.
If a bundle tangles or sheds, separate the two causes. Matting along the length is about the hair: cuticles running in both directions or damaged by stripping. Hair coming out at the weft is about construction, and our post on shedding, matting and slippage walks through the root causes.
A scorecard for your sample
Mark each test pass or fail. A raw claim survives only if the hair passes all of them; one clear fail on the bleach or wash test means the hair has been processed, whatever the label says.
| Test | Pass | Fail |
|---|---|---|
| Burn | Ash, burnt-hair smell | Melted bead, plastic smell |
| Bleach strand | Even lift through the stages | Patchy lift, colour bands, gummy or snapping strand |
| Wash and air-dry | Same feel after the third wash; natural texture returns | Goes dry, rough or limp once the coating washes out |
| Cuticle slip | Drags tip to root, smooth root to tip | Feels glassy and identical both ways |
| Tangle and shed | Combs through; little hair at the weft | Mats along the length; hair pulls free from the weft |
| Smell | Neutral, like clean hair | Chemical, sour or heavily perfumed |
| Weft | Even stitching; natural shade variation | Loose stitching; uniform dyed-looking colour sold as raw |
A full pass means human, unprocessed, cuticle-intact hair: what raw must be, and also what unprocessed virgin hair is. The last step is not a test.
What to ask the vendor in writing
Donor count and origin cannot be tested, so the seller has to state them on paper you keep. Ask for these on the proforma invoice or in an email before you pay:
- Donors per bundle. A number, not a word. "Raw" without a donor count is a label.
- Processing. Has the hair been coloured, permed, steam-set, acid-washed or coated? A yes or no for each.
- Texture. Is the pattern the donor's own, or set by steam?
- Origin. Where the hair was collected. Country names on a product list are often texture styles, so ask where the hair itself came from.
- Construction. Machine weft, single drawn or double drawn, and the weight per bundle.
- What happens if the bulk order differs from the sample you tested.
Grade letters do not answer any of these; the hair grades guide explains why. For the wider check of a supplier, not just the hair, see how to vet a hair supplier.
How this differs from checking a supplier's sample
Our post on how to check human hair quality before buying is about judging a supplier's sample as a whole: weight, length, finish and whether the bulk will match. This page is narrower. It asks whether hair sold as raw is what the word says, and where testing stops. If you plan to colour the hair, our guide to bleaching, toning and colouring extensions picks up after the strand test.
Our raw hair, and how to test it
Our raw hair is South Indian temple hair for most markets, and Indian hair from private donors for Israel and Muslim-majority markets. Each raw bundle is one donor's hair, in the texture and shade it grew in: straight, natural wavy or natural curly, in natural dark shades. Names such as Vietnamese or Burmese on our product list are texture styles made from Indian hair, not hair collected in those countries. Ask us the same written questions you would ask any vendor, and put them on the enquiry.
Test it the way this page describes. There is no minimum order, so you can start with a few bundles of raw Indian hair or a sample kit, run the scorecard and order in volume only once it passes. Wholesale terms for raw hair are on the raw Indian hair vendor page and under bulk and raw hair.
Questions people ask
- How can you tell if hair is raw?
- Run several tests on a sample: wash it three times and let it air-dry, feel the cuticle, lift a strand with bleach and look closely at the weft. If it passes, the hair is human, unprocessed and cuticle-intact. That fits raw hair, and unprocessed virgin hair too. Whether it came from one donor rests on the vendor's written statement.
- Does the burn test prove hair is raw?
- No. The burn test only separates human hair from synthetic fibre: human hair burns to a crumbly ash with a burnt-hair smell, synthetic melts into a bead. Processed hair, Remy hair and some animal hair all burn the same way, so a pass tells you nothing about raw.
- Does raw hair float or sink in water?
- The float test is widely shared but it is not a reliable sign of anything. Whether strands float or sink depends on coatings, oils and trapped air as much as on the hair. Use the wash and air-dry test and the bleach strand test instead.
- Can a home test prove raw hair is from a single donor?
- No. No test you can run at home or in a salon shows how many people a bundle came from or which country the hair grew in. Natural shade variation and a single natural texture are consistent with one donor, but they are not proof. Ask the vendor to state donor count and origin in writing on the invoice.
- Why does raw hair look different from bundle to bundle?
- Because each raw bundle is one person's hair in the texture and shade it grew in. Two donors rarely match exactly, so raw bundles vary more than virgin or Remy hair matched from several donors. That variation is expected; a set of 'raw' bundles that look machine-identical is worth questioning.
- What does Suvita mean by raw hair?
- Hair from a single donor that has not been chemically processed: no colour, no perm, no steam-set pattern, washed and conditioned only. It is South Indian temple hair for most markets, and Indian hair from private donors for Israel and Muslim-majority markets. It comes only in the donor's own texture and shade.
