Our ancestors knew that washing hair with nettle decoctions stimulates growth and keeps the hair healthy. In GRANDMA SAID we used this well-known ingredient in an unusual combination with precious tamanu oil, sometimes called “miracle” oil. Native to Southeast Asia, tamanu oil is a great source of hair nutrients, used to regenerate and restore hair and scalp to its healthy state. For its properties tamanu oil is often used on broken, chemically treated and weak hair.
