Looking to learn more? Although we have lots of information on this website, I highly recommend taking classes/courses through Aromahead Institute, which is approved by both NAHA and AIA. That is what I did! 
Andrea is a wonderful teacher who makes you feel like she is right there with you as you take each class. The step-by-step videos are very helpful in showing you how to make each of the products in the course, giving you the confidence you need to make the blends and products yourself.
All courses are online - go through them at your own pace! You have access for life.
A great place to start is the FREE introduction course.
Beginner with no previous training?
If you aren’t interested in becoming certified, and just want enough education to properly use essential oils for your own use, you might want to consider these courses:
Aromatherapy for Natural Living - this class is perfect for moms and families new to essential oils. Topics covered: intro to essential oils, using essential oils with your children (even little ones!), how to make your own cleaners using essential oils, and even luscious creams and balms to pamper your skin. This course has it all, and is affordable to boot!
Body Butters and Lip Balms - this course will teach you how to make fail-safe body butters, lip balms, deodorants, and more. Everyone can enjoy this course, especially if you like knowing what is in your body care products, or if you have sensitive skin. Also makes for great gifts. You could even open your own online store
Want to be a Certified Aromatherapist?
Aromatherapy Certification Program (ACP) - If you are interested in becoming a certified aromatherapist (or if you don’t care about being “certified” but just want the knowledge) - this is the program for you! This is the first class I took, and boy did I enjoy it. You don’t need any previous training. Tons of thorough information, full of data sheets for dozens of oils, as well as videos and access to a forum for discussions. 235 hours of training. Includes the Anatomy & Physiology course.
Advanced Graduate Program (AGP) - Did you graduate the Aromatherapy Certification Program and just can’t get enough? This is your next step. 125 hours of training.
Want to be a Clinical Aromatherapist?
Scholar’s Program - when you graduate from this program, you will have 400 hours of training under your belt. This program includes the ACP, AGP, and 40 hours of electives. This is the highest standard of aromatherapy education approved by AIA and is exclusive to Aromahead Institute.
A Massage Therapist who wants aromatherapy training?
Aromatherapy for Massage Therapists - this course is to help teach massage therapists how to incorporate aromatherapy in their practice (although anyone can register). Learn how to better help your clients: reduce their muscle pain, provide inhalers for headaches, make diffusers to calm the mind, create and implement salves, and so much more.
