Starter locs (newly installed): Every 3–4 weeks to keep the sections neat and help them lock.
Mature locs: Every 4–6 weeks, or as needed based on your hair growth.
Interlocked locs: Every 6–8 weeks, since they stay neat longer.
Locs require regular washing (every 2–3 weeks) with residue-free shampoo, consistent moisturizing with water-based sprays and light oils, and protection at night using satin/silk bonnets to prevent lint
