There are a ton of books about makeup out on the market today, but not all are alike. I've found the two books that contain the most vital information anyone in the industry can benefit from!
This is THE BOOK of makeup. It is bigger than my physics textbook from college! Some of the information in this book is never spoken of anywhere else in any other book, a very well kept secret! It includes pictures with step by step information, great for future reference! I don't want to ruin anything for anyone, so you have to see for yourself :)
Color theory is obviously a gigantic part of makeup artistry, and knowing everything and anything about the topic can only benefit you. This book is the nitty gritty of color theory, a must have of any sort of artist.
