Do NOT retighten, or allow others to retighten, your locks too tightly, too often, or too close to the scalp - this could damage your locks, as well as your scalp/grid. All locks swell after styling and retightenings; give them room to do so. Please consult with your SL Consultant, if you think your locks are being retightened too tightly. Sisterlocks™ and Interlocks are hair locking systems generally used on natural hair. These styles in themselves, if properly maintained, will be beautiful! Attempting a "permed hair look" around your edges may damage your locks, grid and/or scalp. This applies to hair styles in general, not just locks.
