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.

If you are looking for a book with precise recipes for different shampoo and conditioner bars this is not it. This is more science for the crafter who wishes to formulate their own recipes. I have purchased several books which inform but not overwhelm the home soap maker.

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.
