Masterclass Testimonials
Meet the makers behind these beautiful brands and discover how they've used the Masterclass to create their own shampoo and conditioner bars.
“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.”

"From course to successful launch! This masterclass is an absolute goldmine for product developers. It provided me with a deep understanding of ingredients and pH balance, making it easy to tweak and refine the formulas to fit our vision perfectly at KaliFlower Organics.
Thanks to this course, we successfully developed and launched three shampoo bars and three conditioner bars for our brand.Highly educational, well-structured, and highly recommended for any indie beauty entrepreneur looking to create professional, high-performing products that sell!"

"I absolutely loved Kristina's course. It changed the way I look at shampoo bars and made it crystal clear why certain ingredients are essential for achieving satisfying results.
​
I highly recommend this course. In today's world of endless "experts," it's hard to find someone with genuine experience and deep knowledge. Kristina's expertise really shines through, and I learned so much from her."

"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 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."

"The class gave me the confidence to move from simply making products to understanding the science behind creating a well-balanced, high-performing shampoo bar.
I especially appreciated the detailed guidance on ingredient selection, formulation techniques, troubleshooting, and creating products that are both effective and gentle on the scalp. The knowledge shared has helped me improve my formulations and inspired me to continue developing high-quality, small-batch products through Essence Elixir.
What I valued most was your willingness to share your expertise so openly and support makers at every stage of their journey. The Masterclass has been an important step in helping me grow both creatively and professionally."

"I create handmade shampoo bars and cold process soaps using carefully selected, skin- and hair-friendly ingredients.
Your masterclass helped me better understand formulation and improve the quality of my shampoo bars, giving me more confidence in my work."

"I finally understood how ingredients work together, rather than just following recipes blindly.
​
Since taking the Masterclass, I've developed several formulas tailored to individual clients' haircare needs. I started by gifting products to friends and family, and today I have regular customers who genuinely swear by my bars.
​
It's been an incredibly rewarding experience, knowing that I can help someone genuinely love their hair-wash day.
​
Don't overthink it, just do it. Even if you never plan to sell a single bar, the recipes alone are worth it. They're far superior to anything I've come across and tested on my own from the internet."

"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.“

“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.”

"The shampoo bar Masterclass has been such a valuable part of my journey. What I appreciate most is how user-friendly and solution-focused your method is, especially for different hair needs and struggles.
The formulas gave me the confidence to create natural, effective shampoo bars that people genuinely enjoy and come back for.
One of my biggest takeaways was learning how to make products that are gentle, practical, and truly supportive for different hair types and needs. I would highly recommend your Masterclass to anyone wanting to create high-quality shampoo bars with confidence."

"I started making natural products for myself and friends after deciding to remove hormone disruptors from my daily routine. I was happy with my products but wanted to learn more and improve my skills, which led me to the Masterclass. Since then, I've expanded into different types of bars, added them to my product line, and gained the confidence to experiment more freely."

"I've been making handcrafted soap and skincare products for several years, but I wanted to expand into hair care and create shampoo and conditioner bars that aligned with my natural, small-batch philosophy.
The Masterclass gave me the confidence to move beyond simply following recipes and truly understand formulation. I learned how ingredients work together, how to troubleshoot issues, and how to tweak formulas to create products that perform exactly the way I want them to.
Using the knowledge I gained, I was able to develop and customize my own shampoo and conditioner bars, improve my formulation skills, and confidently introduce new products to the Hazel & Grace collection.
The course helped transform hair care from an idea into a growing part of my business, and I'm excited to keep building on what I've learned."

“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 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."

It was very informative and I made my first few shampoo and conditioner bars immediately following the class.

"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!"
