Raw Human Hair Tester — Natural Black (1B), Unprocessed | Research Grade

Raw, unprocessed human-hair tester for product and cosmetic research. Single-donor Indian hair, ethically and directly sourced, with the cuticle intact and aligned — never chemically processed, steamed, or color-treated. Supplied as a bound tress for lab and at-home testing. This is a research tester — not one of our $5 weft samples (those are for salon and retail colour/texture matching). It is for evaluating how products perform on real, untreated human hair, including roughness and split-end / damage behaviour. Specifications Color: Natural Black (1B) Length: 6 inches Weight: approx. 8 g Hair: 100% raw, unprocessed single-donor human hair, cuticle-aligned Sourcing: ethically and directly sourced — no chemical processing Age-based testers also available on request. If you need hair from a specific donor age bracket — 25–35, 35–45, or 45–55 — for roughness or split-end research (older brackets carry more natural wear), ask us before ordering. Rough-hair and split-end-specific testers can also be supplied on request. Other colors — platinum blonde, golden blonde, white, and grey — are available on request. Ask about bulk / lab research quantities. For cosmetic and product-testing research use. This is a raw human-hair tester, not a medical product.
