Your grandmother was right. What the science actually says about the oils Sri Lanka has sworn by for generations.
Your grandmother was right, and now the literature agrees with her. The oils this island has sworn by for generations — coconut, king coconut, castor — each earn their place, just not interchangeably.
Coconut oil is the only one shown to penetrate the hair shaft and reduce protein loss, which makes it a genuine pre-wash treatment rather than a topcoat. Castor is the thickest of the three: a scalp-massage oil for slow evenings, not a styling product. King coconut sits between — light enough for ends, gentle enough for daily use.
The rule of thumb from stylists we trust: oil before washing, not after styling. An hour under a warm towel beats an overnight pillow sacrifice every time.
