How Do Rastas Grow Their Hair: Locs Guide for Growth

Rastafarians grow their hair by simply not cutting it. That is the foundation of the practice. By abstaining from cutting, and often from combing or brushing as well, the hair is allowed to naturally knot and mat over time into the distinctive locks most people recognize. For Rastafarians, this is both a spiritual commitment rooted in Levitical scripture and a visible expression of living as naturally as possible. By the late 1960s, nearly all Rastafarians wore dreadlocks, and the style has since become one of the most recognized hair identities in the world. But if you are reading this because you want to actually grow healthy, strong locs, there is more to the story than just putting down the scissors.

What 'growing Rastafarian hair' really means

The first thing to get straight is the difference between hair growth and hair length retention. Your hair grows from the scalp at roughly half an inch per month regardless of what style it is in. Locs do not make your hair grow faster. That is a myth worth busting right away. What locs can do is help you retain length, because hair that is locked together is less exposed to daily friction, manipulation, and breakage than loose hair. So when you see someone with locs down their back, that is the result of years of growth combined with good retention, not some accelerated biological process.

The traditional Rastafari approach is specifically about non-interference: no cutting, no combing, and in the strictest interpretation, no twisting or styling either. Some households consider combing, brushing, or twisting the hair to be forbidden. This is the freeform or 'natural' route, where hair knots entirely on its own. However, plenty of people who want locs take a more managed approach: they use palm rolling, comb coils, or interlocking to guide the hair into defined sections from the start. Both are valid. The choice affects how your locs look and how long certain stages take, but it does not change your underlying hair growth rate.

Prep your hair before starting locs

If you are starting locs today, the condition of your scalp and hair matters more than most people realize, especially if you’re learning how to grow freeform dreads and want to lock in healthy, buildup-free hair from day one. Buildup from heavy creams, waxes, or grease will interfere with the locking process and create residue that is very difficult to remove once hair is locked. Before you begin, do a clarifying wash to strip away any product buildup. Use a residue-free shampoo, meaning one that avoids waxes, heavy fragrances, sulfates, and dyes. Some people need two rounds of shampooing to fully clear the buildup, especially if they have been using thick pomades or petroleum-based products.

Your hair length and type will also shape what starting method works best. Most textured and coily hair types (the majority of Black hair) will begin to coil and knot naturally if left alone, but the process can take months of patience before sections become defined. If you want more uniform sections from the start, a loctician can set you up properly. Going in with clean, healthy hair and a clear scalp is the best foundation you can give yourself.

Set your expectations now: the early stage of locs, often called the starter or baby loc phase, looks nothing like mature locs. Your hair may look frizzy, uneven, or puffy for months. This is completely normal. Knowing that ahead of time will save you a lot of frustration.

How to form and maintain locs, step by step

There are three main methods for starting and maintaining locs, and each has real-world trade-offs. New York State's natural hair styling curriculum formally recognizes all three as core locking techniques:

1. Palm rolling: You twist sections of hair between your palms in a consistent direction to encourage the hair to coil and mat. This is the most common maintenance method and takes roughly 45 minutes to 1.5 hours for a full head depending on how many locs you have. Palm rolling is gentle on the scalp and works well for keeping locs looking neat.
2. Comb coils (Nubian coils): A fine-tooth comb is used to coil small sections of hair at the root, creating defined starter locs. This method works especially well on shorter textured hair that has enough natural curl to hold the coil.
3. Interlocking: A tool or finger is used to pull the tip of a loc back through its own root, creating a knot that holds the new growth in place. Professional interlocking can take 3 to 4 hours for a full head. It holds longer between maintenance sessions but can stress the follicle if done too tightly.

Washing your locs

Washing is non-negotiable for loc health. Skipping washes allows dead skin, sweat, dirt, and product residue to accumulate on your scalp, which can lead to irritation, odor, and a compromised environment for hair growth. During the starter phase, some locticians recommend waiting about four weeks between washes to reduce the chance of new locs unraveling. Once locs are more established, a wash every two to three weeks is a common and practical target for most people, though your activity level, scalp oiliness, and climate may push you to wash more frequently.

Always use a residue-free or clarifying shampoo designed for locs. Diluting your shampoo with water in a squeeze bottle helps distribute it evenly without needing to scrub aggressively. Rinse thoroughly. Any shampoo left behind becomes buildup. If you feel like your locs have accumulated significant residue over time, a clarifying treatment can help break it down, but you may need to repeat it to fully clear the locs.

Drying your locs

Drying matters as much as washing. Locs hold water deep inside the shaft, and if they stay damp for too long, mildew can develop inside the loc, which causes a distinct sour smell and is very difficult to reverse. After washing, squeeze (do not rub) your locs with a microfiber towel or a clean cotton t-shirt. Then sit under a hooded dryer for 20 to 30 minutes or allow them to air dry in a warm, ventilated space. Avoid going to bed with wet locs.

Retwisting schedule

During the starter phase, retwisting every four weeks is the standard recommendation, with some people doing it every two to three weeks in the very early stages. As locs mature and lock more firmly, you can stretch that interval to every eight to twelve weeks or even longer. Over-retwisting is a real risk: twisting too frequently or too tightly at the root is a direct cause of traction alopecia, a form of hair loss caused by repeated tension on the follicle. If you are doing interlocking, the same caution applies. Tighter is not better.

What to actually use: products and routines

This is where a lot of people go wrong, often because of well-meaning but outdated advice. Heavy waxes, petroleum jelly, thick butters, and grease-based products were historically common in loc routines, but they bind with minerals in water and accumulate inside the loc. That buildup is nearly impossible to fully wash out, it interferes with locking, and it creates a breeding ground for bacteria. Avoid them.

What actually works for loc health is keeping it light and water-soluble. A good routine looks like this: a residue-free shampoo as your base cleanser, a light leave-in conditioner or water-based moisturizer applied between washes to prevent dryness, and a light oil (jojoba, almond, or diluted tea tree) applied sparingly to the scalp to address dryness without clogging follicles. If you have a scalp condition like seborrheic dermatitis, be careful with heavy oil application. Some oils may help manage flaking in certain people, but coconut oil in particular can aggravate seborrheic dermatitis in some cases. If you have ongoing scalp issues, get that addressed by a dermatologist before doubling down on oils.

For retwisting, a water-soluble loc gel that leaves no residue is far better than any wax-based product. Read labels. If a product lists beeswax, lanolin, or petroleum as key ingredients, skip it for use in locs.

How long this actually takes and what affects your progress

Hair grows at roughly 0.5 inches per month on average. Over a year, that is about 6 inches of new growth from the scalp. But what you actually see and measure depends heavily on retention: how much of that grown hair you are keeping versus losing to breakage. In the early stages of locs, you may also experience significant shrinkage, where the hair appears shorter than it actually is because it is coiling and compressing. This can be discouraging but it is temporary. As locs mature and begin to elongate, that apparent length starts to come back.

Several factors affect how quickly you see progress:

• Genetics: Your natural growth rate, hair density, and curl pattern are largely predetermined. Some people grow hair faster than others, and that is not something a product or routine can fully override.
• Nutrition: Hair follicles are metabolically active and need adequate protein, iron, zinc, and vitamins (especially biotin and vitamin D) to function well. Poor diet shows up in your hair over time.
• Scalp health: An inflamed, clogged, or irritated scalp is not an optimal environment for hair growth. Keeping your scalp clean and healthy is directly tied to retention.
• Tension and manipulation: Over-twisting, tight retwists, and heavy locs pulling on the hairline all contribute to traction alopecia. Research from JAMA Dermatology identifies dreadlocks as one of the higher-risk styles for this condition, particularly at the edges and hairline.
• Breakage: Even if your hair is growing from the root, breakage at the ends or shaft erases that growth. Dryness, harsh products, and rough handling all cause breakage.

For a realistic timeline: starter locs typically take 6 to 12 months to begin looking like defined locs. Fully mature, elongated locs with real visible length usually take 2 to 5 years depending on starting length, hair type, and maintenance. There is no shortcut to that timeline, and anyone claiming otherwise is selling you something.

Troubleshooting problems you might run into

Thinning edges or weak locs at the roots

If you notice your hairline thinning or locs feeling thin at the root, tension is almost certainly involved. Stop retwisting that area and give it a rest. This is early traction alopecia, and if caught early, it is reversible by relieving the tension. About 2% of Black men who wear dreadlocks or cornrows show signs of traction alopecia. The hairline and temple areas are most vulnerable. If thinning has been going on for months and the skin looks smooth and shiny (a sign of scarring), see a dermatologist as soon as possible because scarring alopecia is permanent.

Buildup and residue

Buildup usually announces itself as a thick, waxy, or gummy feeling inside the loc, sometimes accompanied by a dull appearance or a musty smell. Switch to a clarifying shampoo immediately and do two wash cycles back to back. Going forward, stop using any wax-based or heavy occlusive product in your locs. Prevention is much easier than removal here.

Scalp problems: itching, flaking, and irritation

Persistent itching and flaking while wearing locs is often seborrheic dermatitis or a similar scalp condition, aggravated by infrequent washing and product accumulation. Washing more regularly is usually the first step. Shampoos with pyrithione zinc or coal tar can help manage flaking. Heavy oil application to a flaky scalp often makes things worse, not better. If symptoms persist after improving your wash routine and simplifying your products, consult a dermatologist. Scalp conditions that go untreated can affect hair follicle health over time.

Dryness and brittleness

Locs can get dry, especially in low-humidity climates or for people with very coily hair that struggles to retain moisture. The fix is simple in principle: water is your best moisturizer. A light water-based leave-in conditioner or a plain water spritz between wash days, followed by a tiny amount of light oil to seal, is the standard approach. Avoid heavy butters in an attempt to compensate for dryness; they sit on top rather than penetrating, and they contribute to buildup.

Shrinkage making it hard to track progress

Shrinkage is especially pronounced in the early and teenage phases of locs. Your hair may look like it is not growing even when it is. One practical fix is to measure from the scalp to a consistent point on the loc every three months using a soft tape measure. You will see growth happening even when it is not visually obvious. Patience here is genuinely the only answer.

Where to start based on where you are right now

Not everyone reading this is starting from the same point, so here is a practical breakdown of next steps based on your current situation:

If you want to go deeper into specific starting approaches, there are detailed guides on [how to grow dreads naturally from scratch](25A44CA6-C438-4471-8584-EA438439F7F1) and how to grow freeform dreads without any manipulation, both of which address the non-interference route more specifically. The core principle across all methods is the same: healthy scalp, clean hair, light touch on products, and patience.

The Rastafari tradition has always centered the idea that natural hair, left to do what it does, carries meaning and integrity. Whether you are coming to locs from a spiritual place or simply because you want them, the practical path to long, healthy locs runs through the same fundamentals: clean scalp, minimal buildup, gentle maintenance, and enough time for your hair to do its thing.
