Yes, this single-ingredient peach kernel oil can be used on hair. Its light texture makes it suitable for applying to the mid-lengths and ends to help soften rough cuticles, add smoothness, and reduce the brittle feeling that can follow washing or heat styling.
For best results, use a small amount—about 2–3 drops warmed between your palms—and gently work it through damp or dry hair from the ears downward, avoiding the roots to prevent a weighed-down look. It can be used as a pre‑wash treatment, left on for 20–30 minutes before shampooing, or as a finishing touch after styling to tame flyaways and add shine. Because the oil is relatively lightweight, it typically does not leave hair feeling greasy if applied sparingly. As with any new product, it is wise to test it on a small section of hair first to see how your hair responds. This product is for external use only and is not intended to treat or prevent hair loss or scalp conditions.
