Taught by Karen Williams and the Aromahead instructor team.
This is where you become a professional.
Most people start with a bottle of lavender and a question. You finish this program able to read that oil’s chemistry, blend it for a real person’s needs, and put your name behind the result.
That is the line between someone who took a good course and a Certified Professional Aromatherapist: real practice, real feedback from our team, and a credential that says you can do the work. For more than twenty years, this is the program where that line gets drawn.
Learn it. Practice it. Prove it.
The certification adds three stages on top of the coursework, the same arc every Aromahead graduate walks: learn the science, practice with real people, then prove your skill to earn the credential.
Master the science and the craft
Everything in the Essential Oil Specialist coursework is included: 7 in-depth lessons, 48 essential oils, the chemistry of how they work, and hands-on blending. Finish it and you earn the Essential Oil Specialist Certificate, your first certificate on the way.
Work with real people, and the body
The included A&P course, A Journey Through Anatomy, Physiology & Pathophysiology, shows you how oils work in harmony with the human body. Then you complete twenty real client case studies. Your personal case-study instructor, an advanced professional aromatherapist on our team, reads every report and gives you feedback, one blend at a time.
Show what you can do, and earn the title
Research and write a paper on an aromatherapy topic you choose, then pass the written exam and the final certification exam. When you finish, you have met the education requirement for NAHA Level 2 and AIA Level 2.
After certification, you’ll be able to…
- Read an oil like a professionalUnderstand the chemistry of why essential oils work, grounded in current research.
- Know what aromatherapy can, and can’t, doGive honest, informed guidance about when oils help and when something else serves better.
- Blend for real needsCreate blends that ease physical symptoms or balance difficult emotions, 100% naturally.
- Keep everyone safeBlend confidently for children, during pregnancy and nursing, and for the elderly.
- Make remedies from scratchBody butters, soaps, salves, and bath salts you formulate yourself, no recipe required.
- Turn it into work you loveWeave aromatherapy into an existing health practice, or begin an entirely new career.
Go deeper than you thought a course could.
Thirty-four video lessons, taught with real plant chemistry in a warm, plain-spoken voice. This is the kind of depth that sets the certification apart from a weekend course.
The chemistry, by family
You learn oils the way professionals do, by their molecular families: esters, monoterpenes, monoterpenols, sesquiterpenes, phenols, oxides. These are the layers that make medicinal blending actually work.
A full class on a single oil
We spend an entire lesson on Eucalyptus alone: its chemotypes, when the cineole type beats the camphor type, what to pair it with to lift mental fatigue. That is the depth you study at, oil after oil.
Read a GC/MS report
Learn to read the lab report behind every bottle, so you can judge an oil’s quality and choose the right one for the situation, the way a professional sources their oils.
Real safety, real math
Use the phototoxicity calculator, learn drug interactions, and blend safely for children, during pregnancy, and for the elderly. Here, safety is a skill you practice, not a disclaimer.
Make remedies with your hands
Body butters, lip balms, hard salves, pain-and-inflammation butters, steam blends, inhalers. You leave able to formulate your own, not just follow a recipe.
The business of aromatherapy
Price your products, label them to FDA guidelines, and choose your path: a product line, a practice, or teaching. The program ends by helping you build your own vision.
A real certification, with a real exam.
By the time you finish, you will answer questions like these, the kind on the exams, with confidence. There is a written exam and a final certification exam, plus twenty client case studies and a research paper, each one read by your instructor.
- Which essential oil is contraindicated when the client is taking warfarin (Coumadin)?
- Which chemotype of Thyme is safe for the skin?
- Citrus oils have a large percentage of which chemical family?
- How many carbon atoms are found in a sesquiterpene?
- Which of the following components is a ketone?
- As an aromatherapist, what should you always do when you’re working with someone?
Every class, module by module.
This is the whole path through the certification, seven modules of real, in-depth study. Every class is a full video lesson with recipes, datasheets, and remedies you can make the same day.

What students say about the program.
Rated 4.9 out of 5 by 88 students in our post-course surveys.
“This program went far and beyond my expectations. I did struggle in the first few lessons because of all the chemistry involved… But looking back now I am so grateful for that overwhelming amount of information. I have learned so much and I am so happy I decided to go for it. I can’t wait to open my business!”
“I found the chemistry videos to be very fun. I had never found chemistry to be interesting until this course. It made the oils so much more meaningful to me. I look forward to learning more and deepening my understanding of how and when to use individual oils.”
“The real-life case studies and interactive sessions were like missing puzzle pieces, helping me integrate and comprehend the information more effectively. Each lesson not only improved my clarity but also significantly boosted my confidence in the subject matter.”
“I felt a little nervous reaching out to case studies, and figuring out how to branch this into my business. But the more I made the products the more I became inspired to help others. Especially when the products worked well for people.”
“I loved the hands-on aspect of this class. Being able to experiment with different oils and products by doing the case-studies was very eye opening.”
“This is absolutely one of the best programs ever! A wealth of information and assistance was provided!”
