Anabel さんのレビュー(2026年 05月 6日)
星 5 個のうち 5 個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

星 5 個のうち 5 個This is a useful book for understanding the chemical process behind making solid shampoo. I believe it is necessary to understand this aspect if one wishes to enter this field. However, the information is sometimes a bit repetitive. Overall, it is a useful compendium for reference.

Regarding your point on repetition, some key concepts are intentionally reinforced throughout the guide to help build a strong formulation foundation and ensure clarity when applying them in different contexts. Thank you again for your feedback, it truly means a lot.

星 5 個のうち 5 個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.
