Wash dreadlocks by saturating them completely, shampooing the scalp with a residue-free cleanser, rinsing until the water runs clear, and drying thoroughly.
Learning how to wash dreadlocks correctly is the difference between healthy, fresh locs and a scalp that’s itchy or an odor that won’t quit. The process hinges on one core principle: you’re cleaning the scalp, and the lather is just traveling through the locs. Most people who struggle with buildup or mildew simply skip a step — usually the rinsing or the drying. The routine below walks through each stage in order, with the exact technique that prevents frizz and keeps your locs locked tight.
Before You Start: Pick the Right Shampoo
The shampoo you choose matters more than the brand. Residue-free and clarifying formulas are the standard for loc care because they lift dirt and oil without leaving anything behind for the locs to absorb. Heavy, moisturizing shampoos and conditioners are the problem — the slip they create encourages hair to detangle, which is the opposite of what locs need.
Conditioner is generally avoided in loc maintenance for the same reason. If your scalp needs extra attention, a diluted apple cider vinegar rinse is a common optional step for deep cleaning, but it’s not a replacement for conditioner and doesn’t belong in every wash. Products designed for locs, like locking gels or residue-free styling creams, should only be applied after washing and drying completely.
If you’re shopping for a new cleanser, our tested rundown of the best dreadlock shampoo options for clean locs covers formulas that won’t build up.
The Step-by-Step Washing Routine
Work through these five steps in order. The whole wash takes about 20 minutes, plus drying time.
1. Saturate the Locs Completely
Wet your hair thoroughly with warm water before any shampoo touches it. Fully saturated locs distribute product evenly, and the warmth opens the hair shaft so the cleanser can actually lift buildup. A quick splash won’t cut it — every loc should be soaked through.
2. Shampoo the Scalp, Not the Loc Body
Apply the shampoo to your palm or directly onto the scalp in a few sections. Massage with your fingertips — not your nails, which can irritate the skin — working the cleanser into the scalp in small circles. You’re not scrubbing the locs themselves here; the shampoo will travel down the shaft on its own with the water.
3. Let the Lather Run Through
Use enough water to carry the suds down the length of each loc. Gently squeeze the lather through the middle and ends. For mature locs, “milking” — squeezing the lather down the shaft — is gentler than rubbing and creates less frizz. Aggressive scrubbing can weaken the loc structure over time and cause it to fray.
4. Rinse Until the Water Runs Clear
This step is where most people cut corners. Rinse thoroughly, separating locs as you go so the water reaches the center of each one. Keep going until the water runs completely clear — no suds, no slippery feeling. Incomplete rinsing leaves shampoo residue deep inside the loc, which becomes buildup and eventually odor.
5. Dry Completely
Press the excess water out with a towel, then wrap the hair in a microfiber towel or a clean T-shirt. Drying is critical: if moisture sits in the locs overnight, mildew can develop. New locs need especially careful handling during this stage so they don’t stick together while drying, but mature locs still need to be fully dry before bed. Many people use a blow dryer on a low setting to finish the job.
How Often Should You Wash Dreadlocks?
Frequency depends on your scalp and how long you’ve had your locs. Guidance from loc-care sources ranges from once a week to every two to three weeks, and some people naturally settle somewhere in between. What matters is consistency — letting the scalp go too long without washing leads to buildup, while over-washing can dry out the skin and locs.
Your scalp’s oil production and your lifestyle are the real deciding factors. If you sweat heavily or use styling products, weekly washing keeps buildup in check. If your scalp is dry, stretching it to every two weeks is reasonable. After the early locking period, some people find they need to wash more often — every day or every other day — to manage scalp oil, and that’s fine as long as the routine stays gentle.
| Washing Mistake | Why It Hurts Your Locs |
|---|---|
| Washing without fully wetting first | Shampoo pools on the surface and never cleans the scalp or inner loc |
| Scrubbing the loc body aggressively | Causes frizz, weak spots, and premature fraying |
| Using fingernails on the scalp | Irritates skin and can cause scabbing or sores |
| Skipping the final rinse | Leaves residue that becomes buildup and invites odor |
| Sleeping on damp locs | Traps moisture that leads to mildew and musty smell |
| Using heavy conditioners | Adds slip that encourages unwanted detangling |
FAQs
Can I use regular shampoo on dreadlocks?
Regular shampoo works in a pinch, but residue-free or clarifying formulas are better for locs. Standard shampoos often contain conditioners or oils that leave buildup inside the loc over time. If you use a regular shampoo, rinse extra thoroughly and watch for film or odor developing — that’s the sign to switch.
Why do my dreadlocks smell even after washing?
A lingering smell almost always points to moisture or residue trapped inside the locs. The fix is a deeper rinse next time, and a much more thorough dry — use a blow dryer on low heat until every loc feels dry to the core. Persistent odor can also come from buildup, which a clarifying wash may resolve.
Is apple cider vinegar good for dreadlocks?
A diluted ACV rinse is a helpful optional step for deep cleaning, not a daily necessity. It can break down product buildup and rebalance the scalp. Mix roughly one part vinegar to four parts water, pour it through after shampooing, and rinse it out completely. Use it sparingly — a few times a month at most.
