Sisterlocks represent a specific locking technique created in 1993 by Dr. JoAnn Cornwell, a hairstylist and entrepreneur. Unlike traditional dreadlocks, which form through matting and can vary significantly in size and appearance, Sisterlocks follow a precise, uniform grid pattern. Each lock is intentionally created using a specialized tool and technique, resulting in uniform, pencil-thin locks that typically measure between 1/8 and 1/4 inch in diameter.

The distinction matters because Sisterlocks operate under a trademarked system with specific standards. The technique involves sectioning the hair into a consistent grid—usually between 200 to 600 locks depending on hair density and desired size—and then using a two-strand twist method with a special locking tool. This structured approach differs fundamentally from free-form or traditional locs, where the formation process is less controlled and locks grow more organically.
The visual result creates a very neat, uniform appearance. Because of their thinness and precision, Sisterlocks can be styled in ways that thicker traditional locs cannot. People with Sisterlocks can wear their hair down in waves, pull it into ponytails, create braided updos, or style individual locks with beads and decorative elements. This styling versatility appeals to many people who want the permanence of locked hair without sacrificing the ability to change their look.
Systerlocks work on various hair types, though they're most commonly associated with textured, curly, and coily hair. The technique requires enough curl pattern or texture for the locks to hold their form. Straight hair can technically receive Sisterlocks through the installation process, but maintaining the locks requires additional products and techniques since the hair has less natural grip.
Practical takeaway: Before pursuing Sisterlocks, understand that this is a structured, precision-based locking system requiring professional installation and ongoing maintenance—not a casual styling choice. The uniformity and styling flexibility are the main benefits that distinguish Sisterlocks from other locking methods.
Getting Sisterlocks installed is time-intensive. Most initial installations take between 8 to 15 hours, typically spread across two or three appointments. During your first consultation, a trained Sisterlocks consultant will assess your hair type, density, and health. They'll discuss your hair goals, how many locks you want, and what final look you're aiming for. This consultation determines whether Sisterlocks are suitable for your hair and helps you understand what to expect.

The actual installation follows a meticulous process. First, the consultant creates a grid on your scalp using a special pattern. They'll section your hair into small squares—this is where the uniformity comes from. Each section is then locked using the two-strand twist method and the specialized Sisterlocks tool. The tool, which looks somewhat like a crochet hook with a specific shape, twists and manipulates the hair strands in a particular way that creates the locked structure.
During installation, your hair is not permanently altered in the way that traditional locs are. Sisterlocks maintain a removable quality if you choose to comb them out later, though this process is lengthy and requires patience. The locks are created through the twist pattern and maintained through regular retightening, but the hair structure itself hasn't been damaged or permanently bonded.
The experience itself requires sitting still for extended periods. Many people bring entertainment, work on a laptop, or simply rest during their appointment. Comfort matters—wear clothes you don't mind being still in, and consider eating beforehand since you'll be in the chair for hours. After installation, your locks will look neat and intentional but will feel somewhat stiff initially. This stiffness decreases over time as you wash and maintain them.
Finding a trained Sisterlocks consultant is important. Only consultants who've completed Dr. Cornwell's training program can authentically install Sisterlocks. The official Sisterlocks website maintains a locator tool to find certified consultants in your area. Prices vary by region and hair density, typically ranging from $300 to $800 for initial installation, with some major urban centers charging more.
Practical takeaway: Budget 8 to 15 hours for installation and research certified consultants in advance. Know that installation is an investment in both time and money, but the precision of professionally installed Sisterlocks differs from DIY or non-certified approaches.
Once installed, Sisterlocks require regular maintenance to stay neat and prevent new hair growth from creating loose sections. Retightening appointments happen every 6 to 8 weeks as new hair grows from your scalp. During retightening, your consultant uses the same tool and technique to tighten the roots of each lock, maintaining that uniform appearance throughout the life of your Sisterlocks.

Between professional appointments, your daily care routine significantly impacts how well your locks maintain. Washing is one of the most important practices. You should wash your Sisterlocks every 2 to 3 weeks using products designed for locked hair. Regular shampoos often leave buildup between the twisted strands, so many people use residue-free or lock-specific shampoos. The washing process is straightforward—wet your locks, apply shampoo, massage your scalp gently, and rinse thoroughly. Unlike some hair types, locks actually benefit from regular washing because it removes dirt and product buildup that can cause odor or mildew.
Drying your locks completely is crucial. Wet locks left damp can develop mildew or odor issues. Most people either air dry by leaving their locks loose or lightly gathered, or use a hair dryer on low heat after towel-drying. Some people use microfiber towels or t-shirts to absorb water rather than regular towels, which can cause frizz.
Product choices matter. Palm rolling—a technique where you roll each lock between your palms to tighten it slightly and smooth flyaways—can be done with a light oil, beeswax product, or specialized lock balm. However, heavy products like thick waxes can accumulate over time and become difficult to remove. Many Sisterlocks wearers use minimal products or none at all, relying instead on the retightening appointments to maintain their locks.
Protective styling, while less critical than with loose natural hair, still matters for lock longevity. Protective styles like updos, low ponytails, or braided styles can reduce tension on individual locks and extend the time between retightening sessions. However, extremely tight styles can cause traction alopecia just as they can with other hair types, so balance is important.
Certain activities require consideration. Swimming in chlorinated pools can potentially lighten your locks and cause dryness—many people rinse or apply a leave-in conditioner beforehand. Ocean water requires similar precaution. Sleeping can cause friction between locks, so some people use a silk or satin pillowcase or wrap their hair in a silk scarf to reduce frizz and breakage.
Practical takeaway: Expect retightening every 6 to 8 weeks and develop a washing routine using lock-appropriate products. The maintenance commitment is ongoing, but relatively manageable compared to other locked styles if you stay consistent.
Your Sisterlocks journey has distinct phases, each with different characteristics and maintenance needs. Understanding this timeline helps you set realistic expectations about how your locks will look and feel throughout their development.

The first three months after installation represent the "baby locs" phase. Your locks look pristine and uniform right after installation, but they feel relatively stiff. During this period, you might experience some shedding around the roots as your hair adjusts to the locked structure. This is normal and not a sign of damage. Your locks may also feel tighter around your scalp than they will later. Many people find their locks feel most uncomfortable during this initial phase and loosen slightly as they mature.
Months three through six mark the transition phase. Your locks become softer and more flexible as they settle. You'll notice new growth at your roots as your hair grows from your scalp. The locks themselves start to show the pattern of your natural hair texture more distinctly. This is when many people first feel like their locks are "theirs" rather
