About 3B springy-ringlet hair
Type 3B is springy ringlets — corkscrew curls the diameter of a Sharpie marker (about 8mm). Denser than 3A, with full body and definition that holds reliably across the head. 3B is the most-represented curl pattern in mainstream beauty media and the type with the widest range of suitable products. It's also the type with the most varied porosity profile, which is why 3B routines differ dramatically from person to person.
Identifying 3B hair
Pattern: full corkscrew loops, Sharpie-marker diameter. Density: typically 100,000-150,000 strands across the head. Shrinkage: 25-35%. The ringlets bounce when stretched and release, and the pattern holds reliably through drying.
Compare with 3A (sidewalk-chalk diameter, looser loops, less density) and 3C (pencil-thin loops, tighter and more packed). The Sharpie test is the easiest: wrap a damp 3B strand around a Sharpie and it should match closely.
What 3B hair needs
Mid-weight to heavy curl creams suit 3B, with the right weight depending on porosity. Low-porosity 3B needs lighter formulas with heat application; high-porosity 3B benefits from heavier butter-based creams and sealing oils. Most 3B routines layer leave-in + curl cream + gel.
The standard 3B wash-day uses the LCO method (Liquid → Cream → Oil) for low-porosity hair, LOC (Liquid → Oil → Cream) for high-porosity. Plop with microfibre 15-20 minutes after styling, then diffuse on low or air-dry without touching.
The 3B wash-day routine
Cleanse with a sulphate-free shampoo once a week, co-wash mid-week if needed. Deep condition weekly under heat (heat cap or plastic cap with body heat for 30 minutes). Apply leave-in to soaking-wet hair, layer a curl cream and gel, scrunch upward, plop 15-20 mins.
Hard-water UK regions (London, SE, Anglia) need monthly chelating clarifying — calcium and magnesium build up on 3B's natural pattern, flattening definition over weeks. Use a chelating shampoo (one with EDTA or citric acid) every 3-4 weeks.
Heat styling and 3B
The keratin denaturation threshold is approximately 160°C — above that, you cause progressive permanent damage to disulphide bonds. For 3B-safe heat styling: use protectant (Curlsmith Miracle Shield), stay below 160°C, one pass per section, limit to once monthly for special occasions.
Heat tools at higher temperatures (180-200°C, common for most curling tongs) permanently denature the curl pattern over time. Once damaged, hair stays straighter until cut. For straightening 3B regularly, consider a keratin treatment instead — it's chemically engineered for daily heat use.
UK climate calendar for 3B
Jan-Feb: central heating drops humidity to 30%. Switch to LCO method, layered moisture, weekly steam treatments. Skip humectants in styler (they pull water OUT of dry-air hair).
Jul-Aug: UK humidity averages 85% with dew points >15°C. Skip humectants (glycerin, honey) in your styler — they pull moisture from the air into your hair, causing the worst frizz of the year. Switch to polymer-based anti-humidity stylers.
All 3B products in this collection are screened for mid-weight to heavier formulations suitable for springy ringlets, with porosity-specific picks called out. Free UK delivery over £25, next-working-day before 2pm.
3B medium-hold styling
Type 3B forms defined spiral ringlets the diameter of a Sharpie marker — tighter than 3A, looser than 3C. The classic 3B mistake is gel only (creates stiff crunchy curls with no movement). The 3B-correct approach is cream + gel: a medium-hold curl cream provides moisture and softness, then a curl gel on top adds definition and frizz control.
3B sweet-spot products: Bounce Curl Defining Curl Creme + Bounce Curl Hair Spray, or Camille Rose Almond Jai + Curl Keeper Original Gel. These pairings give curl definition that lasts 3-4 days without the helmet feel.
Refresh and pineapple
Night care for 3B: pineapple high on the crown in a satin scrunchie, OR a satin bonnet for the whole head. Cotton anywhere causes frizz halo by morning. Day 2-3 refresh: water in a spray bottle + a few drops of leave-in, mist roots, finger-twist any flattened sections.
