Who doesn't want to have a good hair day?

Four lessons dive into the ins and outs of using various product types to treat your hair and scalp, with tried and tested formulations enriched by evidence-based essential oil blends. You can follow our formulas, but we will also teach you to customize your creations!

We start with Lise Andersen’s lesson where she will discusses ingredients that are beneficial to your hair and walks you through how to make hair serums, pre-shampoo treatments, solid shampoos and clay masks,  ready for you to add your essential oils of choice.

Robert Tisserand spends the next three lessons going through three common areas of hair complaints – dry and damaged hair, oily hair and dandruff, and hair loss. He dives into the available research on essential oils and fatty oils that are useful for each of these areas and suggests blends that you can plug into your base formulations. 

At the end of the course you will have the knowledge not only to make, but to customize your haircare, incorporating essential oils for great results – and divine scents!

What previous students say about our courses:

This course was so complete and easy to follow. I loved the live webinars with Lisa and Robert (Lesson 2) and appreciated the structured classroom, as I have discovered that I do best in this type of setting. Also, thank you so much to Hana for her support, input and knowledge for each lesson! ~ Darlene Sekijima

I so enjoyed Lise’s personality and the banter between Hana and Lise. I have a very high stress life, and many times Lise, and Lise and Hana put a smile on my face or made me chuckle when I needed it most. Better than CBD! ~ Sheila McKenna

I appreciated the passion that was put into the course. I stumbled across this by chance and I am so thankful I did. This has expanded my passion and knowledge about formulations. It has enhanced my learning about essential oils. I just want to thank you for offering this course and all that you do. I feel so confident having your institute as my education platform. I am a beginner but feel confident with your amazing education that it wont be long before I am a pro!! ~ Penny Ferguson

The personalized attention and friendly feel. Sometimes you feel like instructors are holding back their best secrets or knowledge. But I didn’t feel like that with either Lise or Robert. Lise was delightful. I felt like I could just pull up a chair with a cup of tea and we could talk formulations! Also being able to learn about blending from Robert was an incredible treat! I would love to have a larger course about that!! ~ Kristi Maxwell

I loved the way the information was organized and the depth of information. I can do some real formulating now- like a pro! I also just love the “freshness” of Lisa and Hana, and the calmness of Robert. What a great team! I also SO appreciate the ongoing feeling that I am dealing with experts when dealing with Tisserand Institute. Thank you! ~ Tina Hammer

I really liked that we had the options to view live or on our own time. This was amazing as my schedule is very volatile and I wasn’t able to be there at the scheduled time as I thought I would. I really like Lisa and thought she was a fun and engaging teacher. I like the video format as well, so that I am engaged visually and can listen, because if it’s just one or the other I find I get distracted too easily. I also liked that some basic formulas were provided to get beginners started with the types of formulas that they are not familiar with. ~ Michaela
Friendly and fun, very well explained. Loved the course – thank you ~ Lilly Zoch
I thoroughly enjoyed this class! Felt like I was right in the same room and also appreciated the candor and humor. There was so much valuable information given by both Lise and Robert.
Not one thing – EVERYTHING! with all my TI courses. Quality of course content, facilitators, teachers and their knowledge, teaching platform – everything! ~ Niki Klelin
The dynamic between Lise and Hana was wonderful — it caused this course to be fun, interactive and so engaging. I’d subscribe to their podcast, if they had one. ~ Rhonda M
I notice I have been mulling things over a lot from this course and that more has gone in than I thought. I’m having my own distilled understandings arriving – which is proof of quality education. Overall i think it was a very good course and that your online platform is superb – as good as any I have used. ~ Nigel Sutton
This is a rare opportunity to study with one of the world’s leading experts on essential oils – don’t miss this chance! Let Robert Tisserand guide you in creating safe and effective blends with parameters based on clinical trials and scientific research.

FAQs

Will there be notes for me to review?
Yes. Each lesson comes with printable handouts of the slides used in the lesson, and additional lesson notes. These are sent to you before each lesson and are for you to keep and refer to at any time.
I am a certified aromatherapist. Will I learn anything new?
Many of our students have commented that our courses helped them grasp what they learned elsewhere in more detail, or complemented their previous education. Some of our students are lifelong learners, and some are teachers.
I am new to essential oils. Is this course for me?
We will let one of our previous students answer this one:

“The information presented is appropriate for all levels, and although I am just beginning my aromatherapy journey it all makes sense.”

Will there be assessments or exams? What kind?
Each weekly lesson is followed by a multiple choice quiz, and there is a summary test at the end of each course. Passing both the weekly quizzes and the final tests is a requirement for certification.
When will the live Q&As take place?

See above in the course description for specific dates. All live Q&As are recorded and you can ask questions any time on our online platform.

Will I be able to ask questions?
Absolutely! In addition to the live Q&A sessions, you can post your questions in the dedicated student forums.
How long will I have access to the recordings?

You will have access to all the recordings and course materials for at least twelve weeks weeks after the last lesson. All the printable materials (notes, handouts, charts, etc.) are of course yours to keep for reference forever. You can also re-enroll into all of our courses for a flat fee of $50 – and enjoy the full access to tutors and fellow learners again. 

Do you offer continuing education credits?
Because we have students from all over the world and of many professions we are not able to offer credits for specific organizations – there are simply too many. However, we issue a confirmation of CE hours gained on the course that you can apply with your professional organization and will be happy to assist with any additional documentation.
What if I fall behind or cannot attend classes?
We have found that running classes on specific dates works best to help you finish a program. You join a class of students, and learn along with them. Many students help each other with queries, and of course our tutors are there too. That said, if you miss a few classes you should be still able to comfortably jump right back in and if you do fall behind you can request extra time. Of course this cannot be indefinite, but we do our best to help you get your certificate.
