The OLAPLEX No.0.5 Scalp Longevity Treatment is a promising addition to any haircare routine, especially for those looking to improve scalp health. The lightweight formula absorbs quickly without leaving any greasy residue, making it easy to incorporate into both wash days and in-between refreshes. After consistent use, my scalp felt more balanced, hydrated, and less prone to irritation. While I can’t speak to long-term results just yet, the initial benefits are noticeable, and my hair feels healthier at the roots. I received this product in exchange for testing and review purposes. All views are my own and are honest.
