Choosing the Curl Size
Afro units are described by curl diameter in millimeters. Smaller numbers mean tighter curls. The curl is heat-set at the factory, so it comes back after washing; what loosens it over time is repeated high heat and bleaching or lightening, which is why afro units are best worn in their delivered color.
| Curl size | Look | Best for |
|---|---|---|
| 4 mm | Very tight coils, closest to 4C hair | Short fades, waves, close crops |
| 6 mm | Defined coils | Short fades and short afro styles |
| 8 mm | Looser coils, softer texture | Short to medium afro styles, twists |
| 15 mm and looser | Loose curl | Longer tops, curly styles |
| Waves | 360 wave pattern | Brushed wave styles |
Our afro units come in 4, 6 and 8 mm curls and in waves. Other curl sizes are made to order.
Ask clients for a photo of their natural hair grown out, and match the curl that blends with the sides and back. For textures beyond hair systems, see our hair texture guide.
Bases That Suit Afro Units
| Base | Why it suits afro units |
|---|---|
| Ultra thin skin | Invisible hairline for sharp line-ups; easy to clean |
| Durable skin | Strong bond, longer life, good for beginners |
| French lace | Breathes in hot weather; natural hairline |
| Hybrid (lace front, skin perimeter), made to order | Natural front with easy bonding |
Because afro styles are usually short, the hairline and edges are on show. A thin skin or lace front gives the cleanest line-up. Read Skin vs Lace Hair Systems and our hair system bases guide.
Specs to Get Right
- 01Color most afro units are 1B or off-black; match grey percentages for older clients
- 02Base color on a deep skin tone, a standard light lace or clear skin base can make the hairline look grey or ashy where the scalp shows through. Ask for a darker lace or a tinted skin base, and send a daylight photo of the client's scalp and forehead with the order so the base color can be checked against it
- 03Density 100% to 120% reads naturally with coily hair
- 04Hair length long enough for the style after cutting; our afro units come in 1" to 4"
- 05Size stock sizes such as 8x10 inches, cut to fit, or a custom template. See How to Make a Hair System Template
360 Waves on a Hair System for Black Men
A wave unit comes with the wave pattern already set, but it only reads as 360 waves when the hair is short and brushed the right way. After fitting, the barber cuts the top down to a short, even length (usually about 1/4 to 1/2 inch) so the pattern sits flat; left longer, the waves turn into loose curl. Brush from the crown swirl outward in the same circular direction every time, using a soft or medium brush with light pressure: the knots on a unit can't regrow hair, so hard brushing that would "train" natural waves just pulls hair out of the base. A durag at night keeps the pattern pressed down. How barbers turn fitting and maintenance into recurring appointments is covered in hair systems for barbers.
