An overnight application designed to nourish and rejuvenate hair while the user sleeps. This intensive conditioning process typically involves applying a specialized formulation to dry or damp hair before bedtime, allowing it to penetrate the hair shaft throughout the night. As an example, one might apply a blend of natural oils and vitamins, covering the hair to maximize absorption, and then rinsing it out in the morning.
This type of treatment is important due to its ability to provide deep hydration and repair damage caused by environmental stressors and styling practices. The extended period allows for optimal absorption of beneficial ingredients, leading to improvements in hair strength, shine, and manageability. Historically, the practice of applying oils to hair overnight has roots in various cultural beauty rituals, emphasizing the benefits of sustained nourishment.
