For Hair:
Massage it directly into your scalp
Take about 5 drops of rosemary essential oil and massage evenly into your scalp after bath or shower. Mix with a carrier oil (like jojoba oil or coconut oil). Rinsing out the oil afterward is optional — though if you do rinse, first let the oil sit on your scalp for at least 5 to 10 minutes beforehand.

Mix it into your shampoo
This can also apply to conditioners, lotions, or creams. Although don't add too much and keep to five drops per ounce of product. Afterward, use the product as you usually would. You can also add 2 to 3 drops directly to any hair product when you apply a dollop of it on your palm before use.

For Eyebrows & Eyelashes:
Using an applicator, lightly brush product onto eyebrows taking care to not saturate the brush. Apply in both directions fully coating the hairs. With the remaining product, brush eyelashes in thin light strokes starting at the lash line. For best results use daily. Results are typically seen 4-8 weeks.

For Skin:
Gently massage a few drops onto clean face, skin, or nails and allow to dry. Apply daily for best results.
