From Real Formulators
⭐⭐⭐⭐⭐
“So glad I found this. I’ve been studying formulation for a few years and I’ve spent a lot of money on courses that ended up being mostly fluff or just didn’t go deep enough. This bundle is different. It’s probably the most complete material I’ve bought so far. I love the scientific approach, it’s not just recipes, it actually explains the ‘why’ behind everything. It’s a lot of information to process, so I’m still going through it, but even the chapters I’ve finished have already helped me clarify things that other courses made confusing. Also, Ashley is great and actually replies to messages, which is rare to find. Definitely worth the investment if you’re serious about formulating <3.”

“I have been loving reading this. I am wanting to figure out a shampoo bar and this has been excellent to understanding what it should have. This has given me a great foundation. It is also easy to find different sections if you are wanting to pounce around to understand something better.”
