The honest answer to how often to retwist your locs is: probably less often than you’re doing it now. Retwisting keeps your roots neat, but it’s also the part of loc maintenance most likely to damage your hair when it’s overdone.
The right interval depends on the stage your locs are at and your hair itself, and for most people, stretching the gap between retwists is better for their hair than keeping it constantly tidy.
Here’s how often to retwist at each stage, why over-retwisting is the real risk, and how to find the interval that keeps your locs healthy rather than just neat. If you take one thing from this, let it be that a neat root is never worth a thinning hairline.
How often to retwist starter locs
In the early weeks, roots are still loose and it’s tempting to retwist often to keep everything looking crisp. Aim for roughly every four weeks. Some people go every two to three weeks in the very first stretch, but that’s about as often as you should ever go, and even then it’s a trade-off.
Starter locs are exactly where thinning and hairline damage begin, because the hair is being handled and tensioned before it has settled. So the instinct to retwist every couple of weeks for neatness works against you.
A little frizz at the root while your locs settle is normal and harmless. Chasing it with constant retwists is not. If you can sit with slightly untidy roots in the early months, your hair will thank you later.
There’s a second reason to go easy early on. Retwisting a starter loc too soon after washing, while it’s still damp and loose, can actually undo the coil or twist you’re trying to set.
Let your locs dry and settle between sessions rather than reworking them constantly. The early months are about patience more than upkeep, and the less you touch new locs, the faster they lock.
How often to retwist mature locs
Once your locs have locked, they hold their shape on their own and need far less upkeep. Every eight to twelve weeks is plenty for most people, and plenty of loc-wearers go three months or longer between retwists with no problem at all.
The thing to understand is that retwisting mature locs is mostly cosmetic.
You’re tidying frizz, not holding the locs together, because mature locs don’t need help staying locked. That means the choice is yours: retwist more often if you like a consistently sharp root, or stretch it right out if you’d rather protect your scalp and let your locs live a little. Neither is wrong, but less manipulation is almost always gentler on your hair.
A lot of people find their locs settle into a natural rhythm over time. As the locs get older and heavier, the roots hold better and the frizz matters less, so the gap between retwists tends to grow on its own.
If you started out retwisting monthly, don’t be surprised if a couple of years in you’re comfortable going three months or more. That’s a sign your locs are maturing well, not that you’re neglecting them.
Should you retwist before or after washing?
After. Retwist on freshly washed hair, once it’s dry or nearly dry, not before a wash. Clean hair holds a retwist better, and washing straight after retwisting can loosen the work you’ve just done.
The usual order is wash, dry properly, then retwist, which is why a lot of loc-wearers combine the two into one wash-and-maintain session every few weeks.
The one thing to avoid is retwisting soaking-wet hair and then leaving it to dry tightly coiled, which traps moisture at the root and can lead to the mildew smell and an itchy scalp. Let your locs dry through before or after the retwist, never sit damp and tightly twisted for hours.
Why retwisting too often is the bigger risk
This is the part that matters most.
Every retwist puts tension on the same follicles at the root. Do it too often, or too tight, and that repeated pull thins the hair over time and can lead to traction alopecia, the gradual hair loss and hairline recession caused by constant tension. It’s one of the most common ways loc-wearers damage their own hair, and it’s entirely preventable.
Watch for the warning signs: soreness or tenderness after a retwist, thinning where the loc meets the scalp, small bald patches, or locs that feel like they’re hanging by a thread at the root.
If a retwist ever hurts, that’s not “working”, that’s too tight, and you should say so. A good loctician will never leave your scalp sore.
Tension is also where the method and the hand doing it matter. Retwisting your own edges too tight is easy to do without noticing, because you’re pulling for neatness and can’t always see what you’re doing at the hairline.
If you retwist at home, keep the tension light, especially around the edges and nape where the hair is finest and most prone to thinning. Those areas need the gentlest touch and the longest gaps between sessions.
It’s worth saying plainly: retwisting too soon is as harmful as leaving it too long. Frequency isn’t neatness for its own sake, it’s a health decision. When in doubt, wait longer. Once you notice thinning starting, our post on thinning roots covers how to protect and recover them.
What happens if you don’t retwist at all
Nothing dangerous. If you stop retwisting, your roots go frizzy, and over time neighbouring locs may start to join at the base. Some people lean into this and let their locs freeform from that point, which is a legitimate look and a lower-maintenance one. So if you’re anxious about missing a retwist, relax.
Skipping it isn’t damaging; it just changes how tidy your roots look. The damage comes from doing it too much, not too little.
The main thing to keep on top of if you retwist less is separating your locs so they don’t merge into one another at the root. A quick separation every so often, gently pulling apart any locs that are starting to join, lets you stretch the gap between full retwists without your locs marrying together.
That’s the low-effort middle ground a lot of people settle into: less retwisting, occasional separating, and a bit of frizz they’ve made peace with.
What affects your ideal interval
A few things move the number for you personally:
- Texture. Tighter, coilier hair holds a retwist longer; looser or finer hair may frizz sooner.
- Maintenance method. Interlocking holds far longer between sessions than palm rolling, so interlocked locs are retwisted much less often. Our guide to interlocking vs palm rolling vs crochet explains the difference and the trade-offs.
- Lifestyle. If you swim or work out a lot, your roots may loosen faster, though that’s a reason to wash more, not necessarily to retwist more.
- How much frizz you’re happy with. A little frizz is not a problem, and tolerating more of it means retwisting less.
Getting it done
Whether you retwist yourself or see a loctician, the rule is the same: gentle tension, and not too often. A professional will keep the tension even and spot early signs of thinning before they become a problem, which is worth a lot if you’re prone to a tender scalp.
For what a maintenance appointment costs around the country, see our guide to how much a retwist costs in the UK, or find someone who does it through the retwist directory.
If you’re doing it yourself to save money, that’s fine, but treat the first few goes as practice and keep them light. It’s better to leave a root slightly frizzy than to pull it tight trying to match a salon finish.
Many people mix the two, seeing a loctician every few months for a proper retwist and doing light upkeep at home in between. Whatever you choose, the frequency is the thing that protects your hair, so build your routine around retwisting less rather than more.
If you’re new to all this and still working out your loc care routine, the guide to starting locs in the UK covers the aftercare basics that keep retwisting from becoming a problem in the first place.
The short version: retwist less than you think you need to, keep the tension gentle, and let your locs do most of the work themselves.
