The Specialist teaches you how. Certification proves you can.
The Specialist gives you the complete coursework and your first certificate. Pathway 3, Aromatherapy Certification, takes the very same coursework and carries it through the credential work: A Journey Through Anatomy, Physiology & Pathophysiology (the A&P course), twenty real client case studies, a research paper, and the written and final exams, guided one-on-one by our team. Everything you learn here carries straight into it.
Students begin here, and go far.
This coursework is where the journey starts. Graduates have used it to launch product lines, build practices, and become trusted resources in their communities.
“Aromahead really brought me so much joy every day during my studies. Coming from the Marketing and Sales and Corporate world it finally fulfilled my love for plants and flowers!”
“I signed up for the ACP course as a birthday gift to myself and I loved the fact that I could take as much time as I needed to complete the course.”
“I am especially grateful to the Scholar's Program for providing me with a sense of mastery: the scope of the course gave me real, relevant breadth and depth that has informed both my…”
What students say about the program.
“I loved learning how to use essential oils safely. … I also appreciated how well the parts that touched on chemistry were taught. I wish I had paid closer attention to chemistry when I was in school, but the way it was broken down in Aromahead Institute made learning so easy.”
“I loved the fact that I could learn at my own speed and on my way. The materials are broken down into easy-to-digest modules with tremendous support from the instructors, and the forum. The access to the essential oils data sheets to GCMS reports are priceless tools not just through the course but also to use as a professional.”
“I loved the research for each oil I chose for a blend. It was the best learning tool in understanding how the oils work with the mind and body. The science behind aromatherapy was so eye-opening and rewarding. Thankful for my Mentor Shelia, her feedback was priceless to me.”
“It allowed me to study at my own rate, learning all about how to safely use essential oils and to blend them with appropriate dilutions. I appreciated being able to learn how to read GC/MS reports so that I could safely substitue oils with similar chemical components but with different aromas.”
“Thank you Aromahead for showing me a whole new world! The courses, exercises, webinars, forum, and feedback are extremely informative and well-structured - based on science, research, and experience. I am so much more confident in my blending skills and know I can rely on a wide community of fellow graduates for support.”
“I have taken many of Aromahead’s courses and have loved every single one of them. They are all full of so much information. My long term goal is to continue learning and become even more confident in using these wonderful oils.”
Every hour counts toward Clinical Aromatherapist.
The Essential Oil Specialist is Pathway 2 on the path to Clinical Aromatherapist. It includes everything in Pathway 1, and every hour here carries forward: into the Pathway 3 Bundle, and all the way to the Scholars Program.

Essential Oil Specialist FAQ
What is the Essential Oil Specialist Certificate?
It is the credential you earn when you complete the Aromahead coursework: 170+ hours of professional-level training in essential oil chemistry, blending, and safe use. On completion you receive your certificate and may use the title Essential Oil Specialist.
Do I need any experience to start?
No. The course is built for both newcomers and people who already use essential oils. It begins with the foundations and builds steadily, at a pace you set.
How long does it take to complete?
You learn on your own schedule with lifetime access. Many students move through the coursework over three to eight months, but there is no deadline, take the time you need.
What is the difference between the Specialist and the full Aromatherapy Certification?
The Specialist is the complete coursework and earns the Essential Oil Specialist Certificate. The Aromatherapy Certification (Pathway 3) builds on the very same coursework by adding A Journey Through Anatomy, Physiology & Pathophysiology (the A&P course), twenty client case studies, a research paper, and the written and final exams, the experiential work that earns a professional credential.
Will everything I learn here count toward certification?
Yes, in full. The Specialist is Pathway 2 on the path. When you continue to Pathway 3, your coursework carries over completely, you only add the experiential work and the exam.
Can I use what I learn to help others or start a business?
Absolutely. Graduates use this foundation to make and sell natural products, guide friends and family, and build the early form of a practice. For client-facing clinical work, continuing to the Aromatherapy Certification is the recommended next step.
Which option should I choose?
Choose the Aromatherapy Specialist at $1,795 if your goal is mastery for yourself, your family, and your handmade products. It includes every Pathway 1 course. Most students who plan to work with clients choose the Pathway 3 Bundle at $2,395: for $600 more it carries the same coursework through to a professional credential, with the A&P course, twenty client case studies, a research paper, and the written and final exams. The Scholars Program at $4,495 is our complete path, for students who already know they want to become a Certified Clinical Aromatherapist.
What does it cost, and are there payment plans?

Do I really get lifetime access?
