How often can I use it, and does it build up over time?

This conditioner is formulated for daily or every-wash use. Because it relies on light oilseed oil rather than heavy silicones or waxes, it rinses clean without leaving a progressive coating that makes hair feel limp or "waxy" after a week. If you shampoo regularly (every 1–3 days), you can condition each time without buildup concerns. People who co-wash (conditioner-only cleansing) or use abundant leave-in stylers, oils, or dry shampoos may notice residue after 2–3 weeks; a monthly clarifying shampoo or an apple-cider-vinegar rinse (1 tablespoon per cup of water) resets the hair surface. For very fine hair that gets greasy quickly, conditioning every other wash and focusing only on the last 5–7 cm of the ends is often enough to keep tangles manageable without weighing down the root area.
