Hair Grading Explained: What 5A, 7A & 9A Really Mean

An 8A, 10A or 12A label does not identify a standardised specification. There is no universal hair-grading authority that makes one seller's number directly comparable with another seller's number.

Grades such as 3A, 5A, 7A, 9A and 10A are seller-defined shorthand. A seller may use them consistently within its own range, but the number alone does not establish material, donor count, processing, cuticle condition, length distribution, construction or measured performance. Ask what the seller's grade means in observable terms.

What the hair-grading scale does not establish

A universal ladder assigning donor counts, expected lifespan or bleaching performance to 3A, 4A, 5A, 6A, 7A, 8A, 9A, 10A or 12A would be misleading. Those details are not fixed by the grade.

• Fibre composition: whether the product is human hair, synthetic fibre, animal fibre or a blend.
• Donor composition: whether a piece contains one donor or mixed donors, and whether that statement applies to one piece or an entire order.
• Processing history: bleaching, deposited colour, coating, perming, relaxing or texture setting.
• Cuticle condition and direction: what is present and how root-to-tip orientation was maintained.
• Length distribution: how much of the stated hair-only mass reaches different lengths.
• Construction: how a weft, tip, tape, lace base or other attachment is made and inspected.
• Performance: shedding, tangling, breakage, colour response and wear under stated conditions.

If a seller uses a grade, ask for its own written definition and compare products within that system. Do not assume the same number transfers across brands.

What to compare instead of the grade

No single attribute guarantees performance, but a useful listing separates the facts below rather than compressing them into one number.

• Material: confirm human hair, synthetic fibre or a disclosed blend.
• Donor composition: single-donor material controls donor mixing within that unit; it does not make different donors biologically identical or guarantee an order-wide match.
• Cuticle direction: Remy is useful vocabulary for root-to-tip alignment, but it does not also prove donor count, processing history or lifespan.
• Processing: ask separately about bleaching, permanent colour, coatings and applied texture.
• Draw and mass: compare the hair-only mass and distribution of lengths. Single drawn and double drawn describe fullness through the ends, not a universal quality tier.
• Construction: shedding can involve the weft, bond or base as well as the hair fibre. Cuticle alignment alone does not establish fibre retention.

Keep colour, texture and origin separate

Natural human hair varies in colour and curl pattern. A seller's stocked range is not a biological limit. Shade codes such as #1B are commercial references, and texture names do not by themselves prove whether a pattern is natural or applied.

Read colour history as its own field: original colour, bleaching or lift, deposited colour and toning describe different steps. Read texture history separately: natural pattern, steam-set texture, perming and relaxing are not interchangeable. Hair that has been chemically lightened is processed regardless of the quality of that work.

Country words can refer to collection, processing, assembly, customs origin or a style name. Ask which meaning applies. For terminology and treatment-history questions, see our raw versus processed human-hair guide.

How to evaluate a grade claim

1. Ask for the seller's definition. What changes between its 7A, 9A and 10A products?
2. Request the underlying facts. Confirm material, donor composition, processing, cuticle direction, draw, hair-only mass, construction and availability.
3. Compare like with like. Use the same length, mass, colour state, texture and construction. A price or grade comparison is weak when those variables differ.
4. Use a sample within its limits. A sample can help assess shade, texture and handling. It cannot authenticate donor identity, geographic origin or the full future order.
5. Plan colour work separately. Previous treatment and current condition matter more than a grade number. Consult a colour professional before attempting lift.

Frequently asked questions

Is 10A hair better than 8A hair?
Not on the number alone. The labels are seller-defined, so compare the underlying specification and the seller's evidence.

What does 12A hair mean?
It means whatever that seller's grading system says it means. Ask for the written definition; there is no universal 12A specification.

Does a high grade mean raw or virgin hair?
No. Grade, chemical-treatment history, donor composition and cuticle direction are separate attributes.

Does a grade tell me whether hair will bleach well?
No universal grade predicts a colour result. Starting colour, previous processing, fibre condition, product history and the colourist's method all matter.

Which hair grade should I buy?
Choose from disclosed facts and the intended use, not the largest number. Ask for material, processing, draw, construction, quantity and matching guidance.
