Is this oil suitable for someone with sensitive skin or scalp?

Rosemary essential oil may not be the best choice for very sensitive skin or scalp due to its potent nature. If you have a reactive skin type, it's crucial to proceed with extra caution.

Before any broader application, always perform a patch test: dilute one drop of the oil in a teaspoon of a mild carrier oil (like jojoba or sweet almond oil) and apply a small amount to the inside of your forearm. Wait 24 hours to check for any redness, itching, or irritation. This step is non-negotiable for all topical use with essential oils.

If you have known conditions like eczema, rosacea, or a very sensitive scalp, it's generally advisable to avoid stimulating essential oils like rosemary or consult a dermatologist first. The product's invigorating and astringent properties, while beneficial for oily and congested skin, can be too strong for delicate skin. Listen to your skin's response and discontinue use immediately if any discomfort occurs.
