"How often should I wash my locs?" is the question I get asked more than almost anything else in my chair. And here's the truth after 20+ years as a loctician: there is no universal number. Stop overthinking it.
The simple rule of thumb I give every client is this — if it feels dirty, wash it. Locs are not the same as loose hair. Because locs are matted, they collect and hold onto things differently, which means your lifestyle plays a much bigger role in your wash schedule than the calendar does.
It Comes Down to What Your Hair Is Exposed To
For a client with a pretty simple day-to-day — minimal sweating, no heavy dust or smoke exposure — washing once a month before a re-twist is typically plenty.
But that changes fast depending on your environment and activity level:
- Work in construction, dusty, or smoky environments? Your hair is going to collect debris much faster. I recommend covering your hair while working when possible, and washing every 1–2 weeks.
- Sweat a lot or work out frequently? Sweat builds up differently in locs than in loose hair, and it can hold onto odor. You may need to wash sooner than the 4-week mark — weekly or biweekly, depending on how your hair feels.
- Notice a scent between washes? You don't have to do a full wash to handle this. Spray the Dr Locs Pre-Cleanse throughout your hair and rinse with water, or spray it onto a cloth and use it like a dry shampoo on the areas that feel dirty. It neutralizes odor without disrupting a fresh re-twist.
The Real Cause of Buildup Isn't Frequency — It's What You're Using
A lot of the "buildup" fear in the loc community isn't actually about how often you wash. It's about the over use of oil, creams, and gels.
If you're using oil on your hair often, understand this: oil is a sealant, not a moisturizer. It doesn't hydrate your hair — it locks in what's already there. Used too often without proper clarifying in between, oil and residue build up and start blocking moisture from ever reaching your hair shaft. This is the same for creams and gels. With creams not formulated for locs, these can also stay within your locs creating product buildup. (Our Dr Locs Amla Extract Conditioner however was created specifically for locs that this does not happen.)
That's exactly why a clarifying shampoo matters so much for loc wearers. It clears out your follicles so moisture can actually penetrate. If you're using oil regularly, work a clarifying wash into your routine consistently — not to wash "more," but to wash right.
Also a good detox is useful to rid of product buildup. However, I want to make this clear-----detoxing locs only makes sense if you decide to stop using products that are causing product buildup. The casual monthly detoxing I see online is confusing to me if you only go back to using the product again that caused the problem. Think about it.
If what you're actually after is moisture (not just sealing it in), reach for true moisturizing products in your wash routine — a moisture mix designed for locs, and a conditioner formulated for locs specifically.
One Thing to Keep in Mind
If you just got re-twisted and then wash your hair, the re-twist will loosen. That's normal. If you're comfortable with that trade-off, wash as often as you genuinely need to. If you'd rather preserve a fresh re-twist longer, that's a good reason to lean on the Pre-Cleanse spot-treatment between washes instead of a full wash.
The Bottom Line
Stop comparing your wash schedule to someone else's timeline. Ask yourself two questions:
- Does my hair actually feel dirty?
- What has my hair been exposed to lately — sweat, dust, oil buildup?
Answer those honestly, and you'll know exactly when it's time to wash. It really is that simple.
