Locs 2026: installation, maintenance, sisterlocks vs traditional locs, the complete guide

Locs are a commitment. Not just aesthetic, but a commitment of time, patience, and often identity. Once installed, you wear them for years. You watch them mature, age, change texture. And that's what makes them one of the most powerful and most demanding hairstyles on afro and textured hair.

Before committing, you need to know what you're getting into. Sisterlocks, traditional locs, butterfly locs, soft locs: each one has its own installation, budget, maintenance and risks. This guide pulls together what to know (including what salons don't always tell you), written with our network of pro locticians in London, NYC, Toronto, Lagos, Cape Town, Joburg, Paris, Brussels and Montreal.

The 4 main loc types

Traditional locs

The oldest and most common. Installation by twisting or interlocking (needle technique). Average diameter 0.8 to 2 cm. Maturation in 12 to 24 months.

Installation: 3 to 6 hours.
Cost: £150-350 / $200-450 / CAD 250-500.
Maintenance: retwist every 4-6 weeks, £40-90 / $50-120 per session.
Commitment: 3-10 years minimum, often longer. Traditional locs are a long-haul relationship.

Sisterlocks

Very fine micro-locs (3-5 mm diameter) installed with a needle following a precise geometric grid. A patented technique, so only certified sisterlocks consultants can install them officially.

Installation: 12 to 24 hours (often split across 2 days).
Cost: £500-1,500 / $700-2,000 (upper price bracket).
Maintenance: retightening every 4-6 weeks, £80-150 / $100-200 per session.
Pros: mobility (you can style them like long hair), faster maturation, fine and worked aesthetic.
Cons: high initial cost, dependency on certified consultants.

Butterfly locs / Goddess locs

"Instant locs" achieved with hair extensions. The visual effect of locs without the commitment of a real loc journey. Wear 6-10 weeks like braids.

Installation: 4 to 8 hours.
Cost: £100-220 / $130-300.
Note: these are not real locs. They take down completely at the end. Perfect for testing the aesthetic before committing.

Soft locs

A recent variant of butterfly locs, with softer, more flexible texture. Often installed with marley hair extensions rather than synthetic.

Installation: 5 to 8 hours. Cost: £130-250 / $170-330.

How to choose: 5 critical questions

1. What level of commitment are you ready for? Real locs mean 3+ years minimum. Butterfly or soft: 6-10 weeks max. Don't confuse them.
2. What initial budget? Traditional £150-350. Sisterlocks £500-1,500. Butterfly or soft £100-250.
3. What recurring budget? Count a retwist every 1-2 months at £40-150. It's the investment people often forget.
4. What professional life? Locs are now widely accepted at work, but the climate varies by sector and country. Sisterlocks and fine traditional locs are the most universally accepted.
5. How do you travel? If you move often, are you ready to find a loctician in each new city? Sisterlocks require certified consultants who aren't available everywhere.

The critical phase: first 6-12 months

The first year of a loc's life is the most complex. Locs aren't yet stabilised, they can come undone at washing, frizz, or lose structure. It's normal, it's maturation. You have to resist the urge to cut everything.

6 rules to get through it:

1. Spaced washes. Once every 2-3 weeks max. Too many washes in the first 3 months equals locs that come undone.
2. Residue-free shampoo. A shampoo that leaves deposit prevents locking. Our shop lists shampoos compatible with maturing locs.
3. No heavy products. Heavy butters, thick oils on lengths build up and prevent tightening. Limit oil to the scalp, in minimal quantity.
4. Regular but not too frequent retwist. Every 4-6 weeks is ideal. More frequent means mechanical stress on the follicle and traction alopecia risk.
5. Visual patience. For 3-6 months your locs will look "messy" (frizz, irregularities, uneven lengths). It's normal maturation, not failure.
6. Satin bonnet at night. Like braids. Especially during maturation when friction is the enemy.

The risks (an honest look)

Traction alopecia

The number-one risk. Retwists too tight, too frequent, on already-tense locs create permanent follicle tension. The follicle eventually dies. The loss is permanent.

Warning signs: thinning temples, receding hairline, locs "falling" from the roots.

Prevention: spaced retwists (6 weeks minimum), light tension, and if you feel a sore temple, immediate stop, rest, and a castor oil treatment for 8-12 weeks.

Mildew (loc mould)

Poorly dried locs after washing can develop fungus inside. Characteristic acid smell, itching, sometimes scalp crusts.

Prevention: complete drying after each wash. Heat cap or hood dryer 30-45 minutes after each shampoo. No skipping.

Buildup

Locs that don't "lock", that stay soft, that don't mature, are often buildup victims: products accumulated in the fibre.

Solution: clarifying shampoo detox (apple cider vinegar diluted 1:4 in water, or baking soda paste). 1-2 times per year max.

Retwist moment: what to know

The retwist (or maintenance) is the central gesture of a loc life. It consists of tightening the roots to integrate new growth into the existing loc. Two techniques:

Palm rolling: the stylist rolls the loc between palms after applying a setting product. A gentle technique, recommended on mature locs and fragile clients.

Interlock / Latch: the stylist passes the loc through the root with a specific needle. More durable but more tense. Avoid if you have fragile temples.

A good loctician uses one or the other based on your profile. Beware of pros offering only one technique for everyone.

Sisterlocks: the special case

Sisterlocks deserve a note. It's a complete system (technique, maintenance protocol and dedicated tools) patented in 1993 by Dr. JoAnne Cornwell. A real sisterlocks install requires:

1. A paid pre-consultation (£40-100).
2. A test session of 50-100 micro-locs to check compatibility (2-3 hours).
3. The full installation over 12-24 hours, often split across 2 days.
4. A home maintenance kit (£50-150).
5. A retightening every 4-6 weeks at £80-150.

Total first-year cost: £1,000-2,500. In exchange you get the most versatile loc family, stylable like long hair, fine and worked in its aesthetic.

Finding a loctician of confidence

Locs demand expertise that doesn't improvise. On Miapoda, multiple loc specialists are listed in London, NYC, Toronto, Lagos, Joburg, Sydney, Paris, Brussels and Montreal. Filter by "Locs" or "Sisterlocks" for the full list. Each profile shows practised techniques, experience and before-after photos.

One last thing: locs are a journey, not a sprint. Find a loctician you can see yourself working with for several years. The quality of a loc life depends as much on maintenance regularity as on the initial install.
