Sisterlocks represent a specific locking method created in 1993 by Dr. JoAnn Cornwell. Unlike traditional dreadlocks, which form through matting and twisting hair, Sisterlocks use a patented interlocking technique that creates smaller, thinner locks. The method involves using a special tool to interlock hair strands at the root, pulling hair through itself in a controlled, systematic way. This technique creates locks that are typically about the size of a toothpick, which is considerably smaller than most other locking styles.

The key distinction between Sisterlocks and other locking methods lies in their uniform size and precise installation method. Traditional locs often vary in thickness and may be created through twisting, braiding, or simply allowing hair to naturally mat. Sisterlocks, by contrast, follow a grid pattern across the entire scalp, creating consistent spacing and diameter. This uniformity means the locks mature at a similar rate and maintain a more polished appearance throughout their lifespan.
The Sisterlocks community is international, with trained consultants operating in numerous countries. The method was developed specifically to work with textured hair types and has gained popularity among people seeking an organized, professional appearance while maintaining locked hair. The smaller size of Sisterlocks means they dry faster than larger locs, which can be beneficial for maintaining scalp health.
Understanding these fundamentals helps explain why Sisterlocks require different maintenance approaches than other locking styles. The tighter interlocking at the base means the hair holds its shape differently, and the smaller diameter affects how products penetrate and how the locks respond to moisture.
Practical Takeaway: Research the differences between Sisterlocks and other locking methods before committing to the style. Understanding that Sisterlocks use a specific interlocking technique rather than twisting or braiding will help you find trained professionals and set realistic expectations for installation and maintenance.
Locating a qualified Sisterlocks consultant requires specific steps since this is a trademarked method requiring formal training. Dr. JoAnn Cornwell established a certification program that trains consultants in the precise technique. The official Sisterlocks website maintains a directory of trained and certified consultants organized by geographic location. This directory remains the most reliable resource for finding professionals who have completed the required training and meet the standards set by the method's creator.

When searching for a consultant, several factors warrant consideration. First, verify that the consultant appears in the official directory—this confirms they have completed the training program. Second, check how long they have been practicing Sisterlocks; experienced consultants may have developed effective techniques for different hair types and textures. Third, examine their portfolio of work. Most consultants maintain photos showing their installations and the progression of how locks mature over time. This visual information helps you understand the quality you can expect.
Distance and cost represent practical considerations in selecting a consultant. Installation prices vary by region and typically range from $300 to $800, depending on hair thickness, length, and consultant experience. Some people travel to specialists they trust, while others prefer local consultants for convenience and ongoing maintenance appointments. Initial installation generally takes 4 to 8 hours, so comfort during the appointment matters.
During your first consultation, reputable consultants will assess your hair type, discuss your lifestyle, explain the maintenance requirements, and answer questions about the process. They should provide realistic timelines for how locks mature and explain what to expect in the first weeks after installation. This conversation helps determine whether Sisterlocks align with your needs and expectations.
Practical Takeaway: Use the official Sisterlocks directory to locate certified consultants in your area, review their portfolios, and schedule consultations with at least two professionals before making a decision. Ask each consultant about their experience, the specific timeline for your hair type, and what maintenance you'll need to perform between appointments.
The Sisterlocks installation process follows a systematic approach that takes substantially longer than many other locking methods. The consultant begins by sectioning the hair into a precise grid pattern across your entire scalp. The number of sections depends on your hair volume and the density you desire—typically ranging from 200 to 600 locks. Each section represents where one lock will form. The consultant marks these sections using a special tool and technique to ensure consistent spacing.

Once sectioning is complete, the actual interlocking begins. The consultant uses a specialized tool that looks similar to a small crochet hook to pull hair through itself at specific points along each section. This creates the interlocked structure that defines Sisterlocks. The process requires significant precision; each lock must be interlocked correctly to ensure proper formation and longevity. The consultant typically starts at the nape of the neck and works upward, taking breaks as needed for comfort.
Installation typically takes between 4 and 8 hours depending on several factors: the thickness and density of your hair, the number of locks you're having installed, the length of your hair, and how quickly your hair accepts the interlocking pattern. People with fine hair or lower density may require fewer locks and less time, while those with thick, dense hair may need more locks and additional time. During installation, wear comfortable clothing and plan to sit in one location for extended periods.
Immediately after installation, your locks will feel different from your natural hair texture. They may feel slightly stiff or structured, which is normal. The consultant will provide specific instructions about caring for your new locks during the critical first weeks. Most consultants recommend waiting 1-2 weeks before washing to allow the locks to set properly. During this initial period, avoid activities that would cause excessive tension on the locks or expose them to water.
Practical Takeaway: Prepare for your installation appointment by wearing comfortable clothing, eating beforehand, and clearing your entire day. Bring water and snacks if your consultant allows. Ask your consultant to explain the sectioning pattern and explain how many locks you're having installed, so you understand what to expect and can recognize proper installation quality.
Maintaining Sisterlocks requires consistent daily and weekly care to keep them healthy and properly formed. Unlike some other locking styles that require less frequent attention, Sisterlocks demand regular maintenance to preserve their structure and prevent breakage. The smaller diameter and tighter interlocking pattern means that neglect shows more quickly than with larger locks.

Daily care includes gentle handling of your locks and keeping them clean and dry. When washing, use the same technique recommended for traditional locks: focus on the scalp and roots while allowing soapy water to rinse through the length of the locks. Avoid excessive scrubbing or twisting of individual locks, which can cause them to unravel or break. Most people wash Sisterlocks 1-2 times weekly, though this depends on lifestyle, scalp condition, and personal preference. Use products formulated for locks rather than regular shampoos, as many commercial shampoos leave residue that builds up over time.
Weekly maintenance includes re-interlocking the locks at the root. This is the most important aspect of Sisterlocks care. As new hair grows from the scalp, the locks can become loose at the base if not interlocked regularly. Many people perform basic root maintenance between professional appointments by visiting their consultant every 4-6 weeks. Some consultants teach clients to perform basic re-interlocking at home, though this requires practice and the proper tool.
Environmental factors affect maintenance needs. In humid climates, locks may require more frequent washing to prevent mildew and mold growth. In dry climates, scalp hydration becomes more critical. Swimming in chlorinated or salt water requires pre- and post-swimming care to prevent damage. The general principle involves protecting locks from excessive tension, keeping them clean and dry, and maintaining proper interlocking at the root zone.
Practical Takeaway: Commit to a regular washing and maintenance schedule before getting Sisterlocks installed. Understand that root maintenance appointments every 4-6 weeks are not optional—they are essential for keeping locks properly formed. Ask your consultant to show you proper washing technique and discuss whether you can perform basic home maintenance or if professional visits are necessary.
Sisterlocks undergo a maturation period after installation that typically lasts 6-12 months, during which they transition from newly interlocked hair to fully formed locks. Understanding common challenges during this
