- Adds a glossy, salon-like finish
🥥 What Is Hair Oil?
Hair oil is a nourishing treatment that penetrates deep into the hair shaft and scalp. It helps repair damage, strengthen roots, and reduce hair fall over time. Hair oils have been used for centuries in Ayurveda and traditional beauty routines.
✅ Key Benefits of Hair Oil:
