After washing, towel‑dry your hair to remove excess water. Take a small amount of serum – a pea‑sized drop is enough for most people – and warm it between your palms. Gently spread the serum over the scalp, focusing on the roots and the area where the hair feels fragile or dry. Massage in a circular motion to stimulate circulation and ensure even coverage. If you prefer, you can also apply a light layer to the mid‑lengths and ends to reduce brittleness, but avoid heavy application that could make the hair look greasy. Once the serum is distributed, style as usual – it can be used before blow‑drying or as a finishing touch after styling. Store the bottle in a cool, dry place and keep it tightly closed when not in use. If you notice any irritation, discontinue use and seek professional advice.
