The application of concentrated treatments designed to nourish and repair hair is a common practice in hair care. This process involves coating the hair strands with a substance rich in emollients, humectants, and proteins, leaving it in place for a specified duration to facilitate deep conditioning. An example includes applying a keratin-based product to damaged hair and leaving it for 20 minutes before rinsing.
The rationale for incorporating this treatment stems from its potential to improve hair’s overall health and appearance. Regular application can lead to increased hydration, reduced breakage, and enhanced shine. Historically, similar practices utilizing natural oils and plant extracts have been employed across various cultures to maintain hair vitality and manageability.
