The duration for which oil should remain in hair is a critical factor influencing the efficacy of the treatment. This timeframe impacts the degree to which the hair shaft absorbs beneficial components and the scalp benefits from the oil’s properties. Example: A light oil may only need 30 minutes, while a thicker oil may benefit from an overnight application.
Optimizing the residence period is vital for achieving desired outcomes such as enhanced hydration, reduced breakage, and improved scalp health. Historically, various cultures have employed oil treatments for hair care, often with specific durations based on traditional practices and ingredients, seeking both cosmetic and therapeutic advantages.
