How long until your locs hit your shoulders? Your waist? Your hip? This dreadlock growth calculator gives you a personalised estimate based on your current loc length and your hair texture. Enter your numbers, pick your goal — and see your timeline unfold.
Average Dreadlock Growth Rates by Hair Type
| Hair type | Monthly growth (cm) | Yearly growth (cm) | Shrinkage factor |
|---|---|---|---|
| 4C — Coily | ~0.45 cm | ~5.4 cm | High (40–60%) |
| 3C/4B — Curly | ~0.70 cm | ~8.4 cm | Moderate (25–40%) |
| 3A/3B — Wavy-curly | ~0.95 cm | ~11.4 cm | Light (10–25%) |
| 2A-2C — Wavy | ~1.15 cm | ~13.8 cm | Minimal (<10%) |
Note: human hair grows on average 1–1.3 cm per month. Dreadlocks appear to grow slower because the hair contracts and loops back on itself as it locks — especially in coily textures. Once locs mature (usually after 1–2 years), length retention improves significantly.
Frequently Asked Questions
How fast do dreadlocks grow?
Dreadlocks grow at the same rate as loose hair — roughly 1 to 1.3 cm per month — but the visible length depends heavily on hair texture and shrinkage. Coily 4C locs may only show 0.45 cm of apparent growth per month due to the hair looping back as it locks. Wavy textures with low shrinkage can see up to 1.15 cm per month of visible growth.
How long until my dreads are shoulder length?
It depends on your starting length and hair texture. Starting from scratch with 3C/4B curly hair, expect roughly 14–20 months to reach shoulder length (~28 cm). Coily 4C hair may take 30–40 months from the same starting point. Use the calculator above for a personalised estimate.
Do dreadlocks grow faster after they lock?
Yes. During the locking phase (usually the first 6–18 months), locs shrink considerably and appear shorter than they actually are. Once locs mature and the internal structure tightens, length retention improves and growth becomes more visible. Many loc wearers notice a visible "growth spurt" after full maturation.
