Masterclass Testimonials
Meet the wonderful makers from around the world and read about their experience with the Masterclass
“I learned so much about shampoo and conditioner bar formulation from taking the Wild Ona Masterclass. I have since been able to offer a full line of clean, zero-waste shampoo and conditioner bars.​
They have been received very well by my customers, and the feedback has been incredible. It feels amazing knowing that I am providing my customers a product that is good for them and is not harmful to the environment.”

"I started using WILD ONA shampoo bars in 2023, and once I made the switch, I never looked back.
​
Kristina has created a beautiful product; now she shares everything- her recipes, her tools, her knowledge, and the secrets behind crafting an amazing shampoo bar.
​
The course feels like she genuinely wants you to succeed.
​​
I now make shampoo bars for myself and my family, and I also sell them in my local zero-waste store."

“I mainly create natural soaps. Since these are not ideal for hair, I started developing solid shampoo bars – as mild as possible and always with the zero-waste philosophy in mind.
​​
Through your Masterclass I gained new confidence in the process and was able to improve my formulations as well as create bars that are more beautiful and of higher quality.”

"I had already been making shampoo bars and had taken other workshops, but was still not fully satisfied with the results. Through your guidance on ingredients, formulas, methods and troubleshooting, I finally understood the exact ratio of ingredients needed and what to adjust to achieve the results I wanted.
​
The Masterclass was also really helpful in learning to scale for bigger batches. Although I now adapt my own formulas, I’m so thankful I purchased your course, which helped me establish my first product range that my customers love. I can highly recommend the Masterclass to anyone who wants to make shampoo bars or expand their knowledge.“

“The Wild Ona Masterclass was so worth the investment! I had enough customers repeatedly asking, "do you sell shampoo?" that I knew it was time to add them to my lineup.
I didn't have the time (or energy) to create and test my own formula, so instead I turned to a maker I had been following and admiring, who was offering a Masterclass on tried, tested, and loved shampoo recipes.
That's where Kristina and Wild Ona came in. The recipes and instructions were easy to follow and yielded beautiful results. Kristina didn't hesitate to answer any questions I may have had. I've been using Wild Ona recipes for a year and my customers love them!”

“Your Masterclass was clear, practical, and really helpful for understanding new formulations. As a cosmetologist, I value the use of pure, nature-derived ingredients.
This class gave me fresh inspiration. I’ve already created new bars with what I’ve learned, and my customers are loving them!”

"Purchasing the Masterclass was a complete game changer for me. I had no idea where to start in terms of making safe & effective shampoo & conditioner bars, but this course provided me with all of the information I needed to know.
The step by step instructions are extremely easy to follow, & the recipes are customizable, so I’m able to personalize the bars to my brand.
Kristina also includes directions on how to scale production, which will be useful for me as my business continues to grow. I’m so thankful for what she’s graciously offered in making this available for other small business owners.

“I had so many customers begging me for shampoo bars, but I didn't know where to start. I didn't like any of the formulas I found online, but once I found your course I knew this was the direction I wanted to go for my business.
They have been an absolute raving success for me! I made my own signature Rosemary + Thyme Shampoo Bar, starting with one of your formulas and adjusting it for my own business goals, and then also used some of your other formulas directly. Thank you so much for putting this together! It's now my own personal favorite shampoo for my hair and I'll never stop making them.

"The Wild Ona Shampoo Bar Masterclass gave me the confidence to create my own meaningful formulations, including a special bar I named ‘Hibiscus Hope’ in honour of my aunt who has breast cancer.
​​
Thank you again for creating such a thoughtful, inspiring, and empowering course. It remains one of the best investments I’ve made in my formulation journey, and I look forward to the day when I can fully launch my own line."

"I recently took a Masterclass on making shampoo and conditioner bars, and it was an incredible experience!
The formulas created a rich, luxurious lather, and the instructions were super easy to follow, even for a beginner. I’m especially excited to keep experimenting with different essential oil blends and natural colorants.
Kristina was so kind and helpful, answering all of my questions with patience and expert knowledge. Her guidance gave me the confidence to take my haircare game to the next level. I’m thrilled to share that I’ll be offering these shampoo and conditioner bars soon on my website—stay tuned!"

"I am very happy with the Masterclass. As a hairdresser, I have been using the shampoo and conditioner in my salon and also sell them both in my salon and on my website.
I initially enrolled in the master class because I had difficulty finding someone to create the product for me, so I decided to make them myself. After searching for a while, I discovered your Instagram and was convinced by the class. I am very happy—thank you!"

"As someone with a background in hair care, I initially found creating my own products a bit overwhelming.
However, after purchasing the Masterclass, the process has become so much easier. I'm now able to create my own shampoo and conditioning bars with minimal adjustments and design flawless packaging.
The step-by-step guidance makes everything straightforward and enjoyable to produce."

Recently, I’ve been branching out into natural hair care, and your course has really helped me expand my formulation skills.

“I absolutely loved the Masterclass!
It was very informative and I made my first few shampoo and conditioner bars immediately following the class.
I’ve been using my new bars myself and my hair feels soft and really compliments my natural wavy hair. I’m obsessed! I plan on selling these in the near future! Thank you so much for sharing!”

"Taking the Masterclass literally changed my business for the better. I have higher sales, and repeat customers because they love the product. I love educating customers, and I am confident in selling my products because of the course. I developed my own recipes based on the materials provided and the ingredients I already had."

"The results have been amazing. No more build-up or itchy scalp, and I now wash my hair less frequently.
My shampoo bars have worked so well that I started selling them at local markets, and I already have happy, returning customers who are just as amazed by the results as I am."

"Rice protein shampoo bars have become really popular, and I've received inquiries from friends who are interested in switching to shampoo and conditioning bars.
That's why I was thrilled to have purchased your Masterclass. I had been struggling to find a recipe that I felt comfortable using, especially in the extremely humid climate of the Philippines.
The portion where you adjusted the recipe for such conditions is truly a game changer."
Florence, Joy, Philippines
"The shampoo and conditioner bar recipes are easy to follow and truly take the guesswork out of making high-quality hair care. My customers love how their hair feels—soft, nourished, and healthy.
It includes step-by-step instructions, plus detailed descriptions of each essential oil, carrier oil, and butter so you understand exactly what you’re using.
Whether you’re starting your own hair care brand or just want clean, effective products at home, this course has everything you need!"
