How to Use Interlock Tools for Locs: A Complete Guide

Interlock tools are essential for maintaining and forming dreadlocks (locs), especially during the early and mature stages of loc development. The interlocking technique involves threading the tool through the base of the loc to tighten and secure the hair, promoting a neat, durable, and well-structured lock. When used correctly, this method strengthens locs, reduces frizz, and prevents unraveling.

This comprehensive guide walks you through each step of using interlock tools effectively, along with expert tips, tool selection advice, and aftercare practices to keep your locs healthy and vibrant.

Step-by-Step Guide to Using Interlock Tools

1. Prepare the Hair
Begin with clean, dry, and detangled hair. Washing your hair 1–2 days before interlocking ensures it’s free of excess oils, product buildup, and debris that can hinder the tool’s movement. Use a residue-free shampoo and avoid heavy conditioners before interlocking, as they can make the hair slippery.

Gently comb or finger-detangle the hair to remove knots. This step is crucial for minimizing breakage and ensuring smooth tool passage. For tightly coiled textures, finger detangling is recommended to preserve curl pattern and reduce tension.

2. Section the Hair
Divide the hair into manageable sections using a rat-tail comb. Common sectioning patterns include parting the hair into four quadrants (front, back, left, right) or using a grid pattern for uniform loc sizing.

Secure each non-working section with clips or hair ties to prevent tangling. Section size depends on your desired loc thickness—smaller sections (0.5–1 inch) create thin, defined locs, while larger sections (1–2 inches) yield thicker, chunkier locs.

3. Choose the Appropriate Tool Head
If using a double-headed interlock tool, select the tip size based on your loc thickness. Smaller hooks (e.g., 0.5 mm) are ideal for thin, delicate locs, offering precision and tighter locking. Larger hooks (e.g., 1–2 mm) work better for thick or mature locs, reducing the risk of splitting.

Adjustable interlock tools eliminate the need for multiple heads, allowing you to customize the hook size. Beginners should start with a medium-sized head for better control and reduced risk of snagging.

4. Start Interlocking
Take a single section and locate the root area where new growth has emerged (typically 0.5–1 inch). Insert the interlock tool just beneath the scalp, threading it through the base of the loc.

Slide the tool down the loc shaft to about 1 inch from the tip, then gently tighten the hook to grip the hair. This anchors the tool and prepares it for twisting. Be careful not to pull too hard, as excessive tension can damage the scalp or break hair strands.

5. Form and Tighten the Locs
Rotate the tool in the same direction as your loc’s natural twist—usually clockwise for right-handed twisting or counterclockwise for left-handed. Consistency in direction is critical; reversing the twist can loosen or unravel the loc structure.

As you twist, the tool pulls the new growth into the existing loc, reinforcing the lock from root to tip. For starter locs or loose tresses, repeat the twisting motion 2–3 times per section to ensure firmness. Mature locs may require only one pass.

6. Repeat the Process
Work systematically through each section, interlocking one loc at a time. Maintain consistent tension and technique across all sections to achieve uniform results.

Take breaks if needed to avoid hand fatigue, especially during full-head maintenance. A complete interlocking session typically takes 1–3 hours, depending on hair density and loc count.

7. Finishing Touches and Aftercare
Once all locs are interlocked, restore moisture with a lightweight leave-in conditioner or natural oil (e.g., jojoba, argan, or coconut oil). This prevents dryness, brittleness, and breakage—common issues after mechanical manipulation.

Inspect each loc for evenness, tightness, and shape. Trim any excessively loose hairs if necessary. For nighttime protection, wear a satin or silk bonnet, or use a satin pillowcase to minimize friction and frizz.
