Fully revised and updated Second Edition of the Diploma in Natural Haircare Formulation

Diploma in Natural Haircare Formulation
Customers want haircare products that give them healthy, soft, and radiant hair that isn’t weighed down or greasy. They’re looking for products that improve the health of the hair and scalp. Many turn to making their own products—but DIY methods with castile soap, baking soda, coconut milk, and harsh vinegars fall short of expectations.

  • You want to be able to offer new and exciting haircare products to your customers.
  • You want your brand to reflect your values, using high-quality, natural, and organic ingredients.
  • You want to finally find the answer to your haircare struggles, and create the products of your dreams.

So… what’s holding you back?


I don't know where to start, or how to properly make the products...


I got frustrated with the lack of information, so I gave up trying...


What I've read on the internet just confuses me...


Nothing I've tried so far has worked, and I'm not sure why...

We’ve heard these very same frustrations from many of our students, and we understand. Haircare formulation isn’t impossible to do at home, but you do need to understand the science and the process before you begin, if you want your products to function properly. Unlike more straightforward products, like lotions or body butters, haircare products require specialized knowledge—and it isn’t impossible to learn!

You just need to know where to look!

If you’ve already been experimenting with DIY haircare products, you’ve likely had an experience similar to these:

"My first and only attempts at making castile-soap shampoo left me with crazy, frizzy, monster hair..."

"My homemade coconut oil shampoo left my scalp itchy and my hair gunky. Coconut milk left my hair too greasy..."

"I'm frustrated. Everything I've tried just dries out my hair, gives it a rough texture, or just weighs it down..."

"My hair needs more than just apple cider vinegar. It needs moisture, but nothing's worked..."

Do any of these problems sound familiar? It can be so frustrating to try again and again, and not know how to fix your formulation problems—or even identify what’s causing the issue in the first place!

Or maybe you have tried formulating haircare products properly—with surfactants and emulsifiers—but have still experienced challenges such as:


Getting the right consistency, viscosity, or slip to your products


Achieving the proper pH


Knowing what extracts, oils, and specialized ingredients to add


Creating the right surfactant system, and making sure there's enough foam with a sulfate-free shampoo


Understanding the natural options for surfactants and conditioning ingredients

There is a much easier way.

Introducing the


Say goodbye to frizzy hair, itchy scalp, and products that don’t work!

The Diploma in Natural Haircare Formulation takes you step-by-step through everything you need to know to formulate your own custom, high-performance shampoos and creamy, perfect conditioners. Learn from experienced and professional formulators and be supported each step along the way.

In this course, you’ll learn:

How to make shampoo without harsh sulfates like SLS, and instead discover a wide variety of gentle, natural surfactants.

How to make conditioners that leave the hair smooth, soft, and silky, with a natural shine (and not weighed down or greasy.)

About the characteristics and needs of different hair types, and how to customize your formulations to suit them.

Real information about what the scalp needs to be healthy.

The functions, properties, and benefits of a wide range of natural and organic haircare ingredients, so you can select ingredients for your formulations with confidence.

How to formulate effective and professional shampoos, conditioners, and hair treatments that leave hair strong, healthy, and shiny.

Praise for the School of Natural Skincare

I am a student of the School of Natural Skincare and part of their community now for about a year. The courses I have done or are doing are well taught and give you the fundamentals that are applicable to formulations. I have experience prior to these courses but still find the information extremely valuable.

Their community is vibrant and their experts are always on hand to help you to understand simple to complex concepts and procedures. I very much appreciate their mission and relatively unbiased approach to promoting healthy cosmetics and formulation techniques that are good for people, the environment and this for our future. Unlike other schools that promote a natural way or organic way for skin care, this school uses real data, real facts and tends to shy away from fear mongering.

Probably the best part of this course and their teaching is the methods used to get you directly involved with making decisions about your business, your products, your exact customers (current or desired) and then servicing those customers with your message and products. Great courses. And the staff and owners genuinely great people.

“I took the course to enable me to add a range of haircare products to my brand, Wellness on Tap.

Before taking the course I had problems finding the right thickener and identifying natural and biodegradable ingredients. Since taking the course my thickener problem has resolved and I am using all biodegradable ingredients in my products.

The Diploma in Natural Haircare Formulation is very well put together. The demonstrations are very helpful. I want to get rid of all plastic containers, so I especially loved the lesson on the syndet (solid shampoo) bars!”

Praise for the Diploma in Natural Haircare Formulation

I am really happy that I took the step and signed up for the Diploma in Natural Haircare Formulation.

“Before I started the course I didn’t know anything about making haircare products – I was at the stage of making homemade soap bars or easy oil based products. So this course was completely different and I had lots of new things to study, such as surfactants and preservatives.

I am really happy that I took the step and signed up for the Diploma in Natural Haircare Formulation. I didn’t have clue how to make a proper working shampoo with all the important ingredients and I have learnt so much. I have already made my first shampoo and testing it on myself, it looks very promising. I don’t have to ever buy shampoo from shops again!

Plus I am much more familiar now with how to read INCI ingredients. I read the labels on all products I buy nowadays and if it has a surfactant I don’t like, I don’t buy it!”

Michaela Bubakova, UK

This course has given me a solid base of knowledge and the confidence to formulate my own products.

“I already had some experience of creating haircare products but I wanted to delve more into the science of hair to formulate products to suit different hair types. I knew how to formulate for oily or dry hair, but not for other types or types in between, so the course was very helpful.

I now know how to formulate correctly for Afro-textured hair. I can now calculate the active matter for my shampoos formulas as I didn’t know how to determine this or what active matter to aim for.

The Diploma in Natural Haircare Formulation course provided me with some new formulas such as making a solid shampoo that’s soap free, a conditioner bar and heat styling products.

I particularly enjoyed the Module on ingredients as it’s so huge; I love it! It provided me with such a wide range of actives and ingredients to use in hair products and I have learnt which ingredients I can incorporate together as I wasn’t sure how to do this.

I enjoyed very much all the formulas, the science of hair, learning about hair types, and what suits each type. I wanted to have confidence in making all types of natural haircare products and this course has given me a solid base of knowledge and the confidence to formulate my own products.”

Inas Mohammed, Egypt

Do you teach how to formulate products for Afro-textured hair?
Our mission is to teach *how* to formulate for specific hair types, including Afro-textured hair. We teach you about the physiological and anatomical characteristics that are typical for different hair types and from this knowledge we build your understanding and ability to formulate for different hair types.

In addition to this we provide formulation examples suitable for many hair types, including Afro-textured, and also formulations targeted specifically at Afro-textured hair types.

As Afro-textured hair has different characteristics and needs we have sections in the following lessons dedicated to Afro-textured hair:

2.4 Hair types and shape covers the structural differences in Caucasian, Asian and African hair in terms of its cross-sectional shape, degree of curl, sebum and shine, grooming ease and breakage, maximum length and strength and the implications of this for haircare

2.7 Caring for Hair includes a section on caring for Afro-textured hair

6.2 Formulating shampoos for different hair types includes formulating for Afro-textured hair. This means you’ll be able to adapt/create formulations designed for the needs of Afro-textured hair.

8.1 Formulating different types of conditioner includes a section on Co-Wash (popular among people with Afro-textured hair type)

8.2 Formulating conditioners for different hair types includes formulating for Afro-textured hair. This means you’ll be able to adapt/create formulations designed for the needs of Afro-textured hair.

8.7 Formulating co-wash Includes a formulation template for co-wash (which you can adapt to create your own formulation) and a  formulation example for co-wash for dry hair.

9.2 Formulating Hair treatments: We include treatments suitable for Afro-textured hair including hair oil, hair butter/mask, clay hair mask.

The course has been designed in such a way as to teach students how to care for and formulate for Afro-textured hair types (and other hair types too).

Are there set lessons to do on specific days or can you do it in your own time?
The course is a self-study, self-paced course so you can study at a time that suits you and complete the course as quickly or slowly as you wish. All the lessons are pre-recorded, so they are available for you at any time.
How long will I have access to the course?
You will have access to the course inside the online classroom for 18 months. You can also download many of the materials to save on your own computer and keep for longer than that and if you wish to renew your access for another year this is possible too, for a small fee.
Why are your prices in US$?
We are an international school with students worldwide. US dollars are the most widely recognized and accepted currency. You can check the exchange rate for your local currency using xe.com.
I don’t have any experience, is the course still suitable for me?
Yes you can certainly take the Diploma class as a beginner. In fact, it will ensure that you learn the correct way to design and create products right from the start, so it is a great way to begin your journey with making products!

We include all the foundations of formulating in Module 1: Creating Professional Haircare Formulations and the practicalities of setting up and lab and making products in Module 3: Lab Skills, Equipment, and Packaging. These modules have been included to enable beginners to join the course and are a useful refresher for students with more experience.

What help is available if I need it?

The course is primarily designed as a self-study course. It takes a very thorough step-by-step approach and each module builds on the next. Therefore as you progress through the course, you’ll gain the skills and knowledge needed to become an expert formulator.

Inside the online classroom, we host a weekly Q&A with our Formulation Tutor, who can answer any questions you have about the course materials as you work through them.

When you sign up to the course you also get to join our private online student community (hosted on Facebook), where you can meet and discuss with other students and graduates, who have lots of knowledge, expertise and ideas to share. 

Where do I buy the ingredients and materials that I need?
As part of the course you receive a comprehensive global supplier list featuring hundreds of cosmetic suppliers all around the world. A shorter supplier list is available on our website here.

We have featured a range of ingredients in the course including those that are more common and easy to obtain. You can find an ingredient starter list here.

Depending on where you are based and what you want to buy you may need to order specialist ingredients from overseas. It is also possible to substitute ingredients for similar ones.
