How long should I leave coconut oil in my hair for optimal nourishment and rejuvenation? Is there a universally accepted timeframe, or does the duration vary based on hair type and condition? Could it be beneficial to consider the specific needs of frizzy or damaged hair when determining this? If I were to apply the oil, should I anticipate that leaving it in for a short period might yield different results compared to an extended treatment? Would a mere 30 minutes suffice, or is it prudent to indulge in a more prolonged application, perhaps several hours or even overnight? What about the thermal effects of wrapping my hair in a warm towel or using a heat cap? Would these techniques amplify the oil’s efficacy? Furthermore, are there any signs or symptoms to watch for that indicate I’ve allowed the oil to linger too long? What insights can be gleaned from those who have experimented with various approaches?
