Sulphates strip more than dirt — they strip the natural oils your scalp needs to stay balanced. Over time that leads to dryness, irritation, and a cycle of over-washing that weakens hair at the root.
Parabens are preservatives with a question mark. They keep products shelf-stable for years, but the trade-off is a synthetic compound your body wasn't designed to process daily.
Going without both means the formula works with your hair, not against it. Less irritation, less buildup, and a finish that looks healthy because the hair underneath actually is.
