The KYVU B21 is a handmade full-bodied rake comb with a handle — crafted around the deepest comb head in the KYVU range. It's hand-sawn from a solid sheet of premium cellulose acetate — a plant-based material derived from wood pulp, with natural flexibility and lasting strength — then shaped, sanded and hand-polished to a glass-smooth, deep black finish you can feel the moment you pick it up. At 20.8 cm and a substantial 31 g, it's a properly-made comb built to last decades with care.

Best for: thick, curly, coily and tangled hair · deep-reaching detangling and styling · easing through dense sections in fewer strokes · sensitive scalps · men & women · hairdressers and home stylists. Prefer a full-head rake for long hair? See the T29 Rake Comb (19 cm). Want a compact, handbag-size rake? See the T19 Compact Rake Comb (17.4 cm).

Its 12 wide-spaced coarse teeth sit in a generous 5.7 cm-deep head — the fullest comb body KYVU makes. The widely-spaced teeth ease through thick, curly or tangled hair in fewer strokes, with less pulling at the roots and less stress on the scalp, while the tall teeth reach deep into dense hair where shallower combs only graze the surface. Equally at home on dry or damp hair.

The shaped handle gives full control and leverage when working through dense, curly or knotted hair, and the substantial 31 g weight gives the comb a solid, balanced feel in the hand — a properly-made tool for hairdressers and home stylists alike. Every tooth tip is hand-rounded so the B21 glides smoothly without scratching the scalp, gentle enough for sensitive scalps and daily use.

Cellulose acetate is warm to the touch and helps reduce static and frizz, so hair sits cleanly with fewer flyaways after every stroke. Because each comb is hand-sawn rather than moulded, there are no mould lines, seams or sharp edges — just a deep, glass-smooth finish that's kind to hair and scalp. The classic deep black finish, hand-polished to a clean shine, looks at home on any dresser, vanity or salon station.

Suitable for men and women, wet or dry hair. Wipe clean with a soft, damp cloth; avoid prolonged soaking and direct heat.

Frequently asked questions

What makes the B21 different from the other rake combs?
Its 5.7 cm-deep head is the fullest in the KYVU range, with 12 tall, wide-spaced teeth that reach deep into thick, curly and tangled hair where shallower combs only graze the surface. The T29 is a full-head rake for long hair; the T19 is the compact, handbag-size version.

Is it good for thick, curly or tangled hair?
Yes — it's built for it. The wide spacing and tall teeth ease through dense, curly or tangled sections in fewer strokes, with less pulling at the roots and less stress on the scalp.

Is it gentle on a sensitive scalp?
Yes. Every tooth tip is hand-rounded so the comb glides without scratching, and the wide spacing reduces pulling — comfortable for sensitive scalps and everyday use.

Does the B21 come in another colour?
Yes. The same full-bodied rake comb is available in a warm tortoiseshell finish as the KYVU T21. It's handmade from cellulose acetate — a plant-based material, cruelty-free and free of any animal product.
