My Sunday Loc Wash Day Routine (Step by Step)

A good loc wash day routine can be the difference between locs that thrive and locs that slowly fall apart from neglect and buildup. Sunday is my wash day and it has been for about two years now. Not because Sunday is special in any technical sense, but because it gives me the whole day if I need it, there is no rush to be anywhere, and starting the week with clean, fresh locs does something good for how I feel going into Monday.

This post walks through my full Sunday routine from start to finish. Every step, every product type, every decision and why I made it. Whether your locs are new or fully mature, whether you wash weekly or every two weeks, there is something here you can take and use.

Why Wash Day Matters More Than People Think

A lot of people treat wash day as a chore. Something to get through. The quicker the better. That mindset leads to rushed washes that do not fully remove buildup, incomplete drying that leads to mildew and odour, and locs that start to deteriorate slowly from the inside without any obvious single cause.

Wash day is actually the most important maintenance practice in a loc care routine. More important than retwisting. More important than oiling. More important than any product you use in between. Clean locs and a healthy scalp are the foundation that everything else builds on. When wash day is done well and consistently, most other problems take care of themselves.

So even though I call it a routine, it is less about following steps robotically and more about giving your hair and scalp the attention they deserve on a regular schedule.

How Often I Wash

Once a week, every Sunday. This works well for my scalp type, which leans oily, and for my lifestyle, which involves working out a few times a week.

For people with drier scalps or less active lifestyles, every two weeks is perfectly fine and probably more common among loc wearers generally. The important thing is picking a frequency you can stick to and not letting washes stretch to once a month or longer. Buildup from products, sweat, hard water minerals and environmental debris accumulates faster than most people expect, and infrequent washing is one of the main reasons locs develop odour, thinning and weakness at the roots over time.

If you are in the starter loc phase, check with whoever maintains your locs about how often to wash. Some methods are more delicate in the early stages and your loctician may recommend a specific schedule while your locs are budding and setting.

What I Use

I keep my product list short. Over the years I have tried a lot of things and come back to a few basics that consistently work.

A clarifying or residue-free shampoo is the most important product on wash day. Regular shampoos often contain ingredients that leave residue on the hair shaft, and over time that residue builds up inside the locs where it is almost impossible to remove without a very thorough treatment. A clarifying or residue-free formula cleans without leaving anything behind. I use this every wash.

After shampooing, I use a lightweight conditioner on the length of my locs but not on my scalp. Conditioner on the scalp can cause buildup and makes locs harder to retwist because the roots get too soft and slippery. On the length and ends it reduces dryness and makes the locs feel more pliable.

For drying I use a microfibre towel and a hooded dryer. The microfibre towel absorbs a lot of the water without the roughness of a regular towel, which can cause lint and frizz. The hooded dryer makes sure my locs are fully dry all the way through, which takes longer than people expect and is more important than most people realise.

The Full Routine

Morning, before I start

I drink a big glass of water and put on clothes I do not mind getting wet. Wash day always soaks my shirt no matter how careful I try to be. I section my locs loosely with a few clips so they are not all tangled together going into the wash. This makes the process faster and ensures every loc gets cleaned individually.

Step one: pre-wash oil treatment

Before any water touches my hair, I apply a thin layer of coconut oil or sweet almond oil to the length of my locs, not the scalp. This is a pre-wash treatment and the purpose is to protect the hair from hygral fatigue, which is what happens when locs absorb a lot of water, swell, and then contract as they dry. Repeated swelling and contracting weakens the hair shaft over time. A light oil coating before washing reduces how much water the locs absorb and protects the structure.

I leave the oil on for about twenty minutes while I do other things. I do not wrap it or apply heat during this step. Room temperature is fine.

Step two: first shampoo

I get into the shower and wet my locs thoroughly. Fully saturated, not just damp. Locs take longer to wet than loose hair because the density slows water penetration. I spend a good two minutes just wetting everything before applying any product.

Then I apply my clarifying shampoo directly to my scalp in sections, working it in with my fingertips using a gentle circular motion. I am cleaning my scalp here, not scrubbing my locs aggressively. The suds from the scalp clean run down through the length of the locs as I rinse, which is enough for a regular week.

I rinse very thoroughly. Longer than feels necessary. Shampoo left in locs is a common cause of buildup and it also makes locs feel dry and dull after drying.

Step three: second shampoo

Yes, I shampoo twice. The first wash removes surface dirt, sweat and product. The second wash actually cleans the scalp and hair properly. After the first rinse my scalp already feels different and the second lather comes up much cleaner than the first.

The second shampoo follows the same process. Scalp focus, gentle circular motion, thorough rinse. By the end of this step my scalp feels genuinely clean, not just rinsed.

Step four: conditioner on the length

With my locs still very wet, I apply a lightweight conditioner from mid-shaft to the ends only. I work through each loc individually, squeezing the conditioner in gently. I leave this on for about five minutes while I handle the rest of my shower routine.

Then I rinse it out well. Conditioner left in locs attracts lint and can contribute to buildup over time if it is not fully removed.

Step five: apple cider vinegar rinse (every three to four weeks)

This step does not happen every wash but I include it here because it makes a real difference when I do use it. An apple cider vinegar rinse removes mineral deposits from hard water, rebalances the scalp’s pH, closes the hair cuticle and adds a noticeable softness and shine.

I mix one part apple cider vinegar with three parts water in a spray bottle or a small bowl and work it through my locs section by section, then let it sit for two to three minutes before rinsing out. The smell disappears completely once the hair is dry.

Step six: towel and first dry

Out of the shower, I use a microfibre towel to squeeze excess water from my locs. Not rubbing, just squeezing from root to tip in sections. This removes a significant amount of water and cuts down total drying time. I then use the towel to blot my scalp gently.

After the towel I let my locs air dry for about thirty minutes. This gives the surface time to dry out slightly before I apply any product.

Step seven: light oil application

While my locs are still slightly damp, I apply a light oil, usually jojoba or argan, to the length and ends. Just a few drops total across all my locs. This is the moisture-sealing step. The locs still have water in them from the wash and the oil goes on top to slow how quickly that water evaporates as the locs finish drying.

I do not apply oil to my scalp at this stage. The scalp is clean and I want it to breathe a little before adding anything.

Step eight: hooded dryer

This step is non-negotiable for me. Air drying locs all the way through takes many hours, sometimes a full day, and in that time the interior of the loc stays wet long enough to develop mildew. Mildewy locs have a smell that is very hard to get rid of and it usually gets worse every time the hair gets wet again.

I sit under my hooded dryer for forty-five minutes to an hour. After that I check a few of my thicker locs at the root by pressing them between my fingers. If they feel even slightly cool or damp inside, I add more time. Fully dry means fully dry, not just dry on the outside.

Step nine: retwist if needed

I do not retwist every wash. Maybe every two to three weeks. When I do retwist it happens on wash day because the roots are clean and the hair is cooperative after a fresh wash. I use a very small amount of a lightweight loc gel or butter, just enough to hold the new growth in place during drying.

If I am not retwisting, I finish under the dryer, do a quick scalp oil application along my parts and I am done.

What Comes After Wash Day

The day after wash day is always my favourite hair day. My locs feel light, clean and defined. This is when I take my monthly progress photo because the hair looks its best and I get an accurate picture of where I actually am.

During the week I maintain moisture with a light water and jojoba spray every two to three days. I sleep on a satin pillowcase every night and wrap my locs in a satin bonnet when I remember. I do not add any more oil or product until the next wash day. The less I put on clean locs between washes, the longer they stay clean and the less buildup accumulates.

The Most Common Wash Day Mistakes

Not wetting locs fully before shampooing. Dry locs do not absorb shampoo evenly and the result is a patchy clean.

Using regular shampoo with heavy conditioners or silicones in the formula. These leave residue that builds up inside the locs over months and years.

Conditioning the scalp. This makes roots slippery, weakens the loc structure at the base and causes buildup right where you least want it.

Not drying fully. This is the one that causes the most damage over time. Mildew, odour, and weakening of the loc structure from the inside.

Skipping wash day when life gets busy. Every week you push past your regular schedule, buildup accumulates and the next wash becomes harder. Consistency is the whole game.

Your Wash Day Does Not Have to Look Like Mine

This routine works for my hair, my scalp and my schedule. Yours will look different because your hair is different. Maybe you wash every two weeks. Maybe you do not use a hooded dryer. Maybe your locs are brand new and you are still figuring out what they respond to.

The framework matters more than the specifics. Clean scalp, clean locs, full drying, light moisture after. Everything else is details you adjust over time as you get to know your hair.

Wash day is an act of care. For your hair and for yourself. When it stops feeling like a chore and starts feeling like something you actually look forward to, you know your routine is working.
