You can spend a fortune at the salon getting instant locs, or you can buy a six-dollar tool and do it yourself. The crochet needle is the shortcut that turns loose kinky hair into tight, natural-looking dreads in hours instead of months. But here’s the thing nobody tells you: that tiny hook will absolutely stab you if you rush it.
I learned that the hard way. Two years ago, I was working on a friend’s hair, moving faster than I should have, and the needle went straight through the loc — all the way into my tongue. Right into the bone. I bled, I swore I’d quit, and my finger swelled up like a grape. But I kept going, because once you understand how to handle this tool safely, it changes everything.
So if you’re a barber, a loctician, or just someone who wants to install their own dreads at home, here’s exactly how to use a crochet needle the right way.
What You’re Working With
Before you even touch the hair, you need to understand the tool. A crochet needle isn’t one-size-fits-all. Most sets come with three different sizes, and they’re labeled by the number of hooks — single, double, and triple. The one with a single hook is the sharpest and the most dangerous. It’s thin, aggressive, and if you’re not careful, it will sink deep into your finger before you feel it.
The double and triple hooks are safer for beginners. They grab more hair per pass, which means you don’t have to stab as many times, and they’re less likely to punch through your skin. I personally use the double hook almost exclusively. It’s the sweet spot between efficiency and control.
You can find these needles on Amazon for about six dollars. They break sometimes — I’ve snapped three of them — but at that price, it’s nothing compared to what you’d spend on salon visits. And if you’re doing multiple heads, it’s worth having a backup.
The Setup: Hair That Actually Works
You can’t use a crochet needle on just any hair. For instant locs, you need kinky hair — the same texture you’d use for braids or twists. Straight or wavy hair won’t lock the same way, and you’ll end up with a frizzy mess that falls apart.
Take a small section of kinky hair and hold it between your thumb and fingers. Don’t grab too much at once. A piece about the thickness of a pencil is plenty. You want the hair to feel firm but not thick enough that you can’t see what your needle is doing.
If you’re working with loose hair to build a new dread, start at the root and work your way down. If you’re maintaining existing locs, focus on the spots where the hair has unraveled or looks fuzzy.
The Technique: Slow Hands Win
Here’s where most people mess up. They see a YouTube video where someone flies through a head of hair in twenty minutes, and they try to match that speed on their first try. Bad idea.
Hold the needle like a pencil, with your index finger resting near the hook for control. Use your other three fingers to manipulate the hair as you work. You’re not just stabbing blindly — you’re guiding the needle through the center of the section while your fingers keep the hair from spreading out.
Insert the needle slowly. I mean really slowly. Push it into the hair at a slight angle, not straight down. You want the hook to catch loose strands and pull them back through the center of the dread. That’s what creates the tight, matted texture.
The most important rule: don’t pull the needle all the way out. If you do, the hook will grab the hair on the way back and yank it out of place. Instead, pull the needle back just enough to release the hair it caught, then reinsert it a little further down. That’s how you build density without tearing the work apart.
Why Going Fast Will Make You Bleed
I can’t stress this enough. The crochet needle is sharp. Not “be careful with scissors” sharp — I’m talking “this thing will go through your nail like butter” sharp.
When I was learning, I was working on a client’s head, and I got cocky. I’d done a few rows without issue, so I picked up the pace. One wrong angle, and the needle slid right through the loc and into my tongue. I felt it hit the bone. Blood everywhere. I told my friend I couldn’t finish, packed up my tools, and went home.
That’s not a story I tell to scare you. It’s a story to keep you from making the same mistake. Go slow. Keep your fingers out of the needle’s path. And if you’re using the single hook, respect it. That one will make you bleed faster than any other tool in your kit.
Working Your Way Down the Dread
Once you’ve got the rhythm down, it’s just a matter of repetition. Insert, catch, pull back, move down. Insert, catch, pull back, move down. You’re essentially knitting the hair into itself, over and over, until the whole section feels firm and uniform.
As you work, rotate the dread with your fingers. Don’t keep stabbing the same side — you’ll create a flat spot. Turn it so the needle hits different angles, and the tension stays even.
You’ll know you’re done with a section when the hair feels solid. Loose strands should be pulled inward. The surface should look smooth, not fuzzy. If you see flyaways, you can hit them again, but don’t overwork it. Too much crocheting can weaken the hair and cause breakage.
What to Expect Time-Wise
A full head of instant locs isn’t a quick job. I charged a client $150 for a retwist, shape-up, beard trim, and crochet work, and the crochet part alone took me about three hours. The haircut after that was another 45 minutes.
That sounds like a lot, but think about it: three hours of work for a style that lasts weeks, and you’re paying less than you would for a single salon visit. If you’re doing it yourself, expect your first attempt to take even longer. That’s normal. Speed comes with muscle memory.
If you’re a barber adding crochet to your service menu, don’t undersell yourself. The time investment is real, and clients who want instant locs are paying for precision, not speed.
Choosing the Right Needle for You
Like I said, I prefer the double hook. It grabs more hair per pass, which means fewer stabs, and it’s less likely to bite you. The triple hook works too, but it can feel bulky in tight spots.
The single hook is for people who really know what they’re doing. It’s precise, but it’s also unforgiving. If you’re a beginner, start with the double. You can always size up once your hands know the motion.
If you’re looking for patterns or projects that use similar techniques, some of the easy crochet patterns for beginners on this site use the same basic hooking motion — just on yarn instead of hair. The hand mechanics transfer surprisingly well.
Final Thoughts
The crochet needle is one of the most useful tools in natural hair maintenance, but it demands respect. Go slow. Keep your fingers clear. And don’t let impatience turn a six-dollar tool into a trip to urgent care.
If you’re serious about learning, grab a pack of kinky hair, a double-hook needle, and practice on a loose section before you touch anyone’s head. You’ll stab yourself at least once — we all do. But if you pay attention, that first mistake will be your last.
