Rosemary oil can be a beneficial addition to your scalp care routine due to its potential to improve hair growth and scalp health. When using rosemary oil on your scalp, it's important to consider the duration of application.

Ideally, you should leave rosemary oil on your scalp for at least 30 minutes to allow it to penetrate the skin and provide its benefits. However, if you have sensitive skin or experience any discomfort, it's best to rinse it off sooner.

Some individuals prefer to leave rosemary oil on overnight by applying it before bed and washing it off in the morning. This extended duration allows for better absorption and potential enhancement of its effects.

Remember to dilute rosemary oil with a carrier oil, such as coconut oil or jojoba oil, before applying it to your scalp. This helps prevent skin irritation and ensures proper distribution of the oil.

It's worth noting that individual experiences may vary, and it's always a good idea to perform a patch test before applying any new product to your scalp or skin. If you have any concerns or specific conditions, consulting with a dermatologist or trichologist is recommended for personalized advice.
