Welcome to the Queendom! I'm Sarah Ingle, basically your friendly neighborhood Rapunzel. Lately we've been on a quest to find the best and worst hair advice on the Internet. That quest evolved into our current series on the science of hair and busting haircare myths. Hope you'll join us!

How do I get hair info?
1. I read books by top hair researchers, watch their lectures, and ask them questions.
(I also read many published studies, but these three items come first to give context to interpret studies properly)
2. I have a Master of Science degree in Marketing -- but not the advertising kind. My graduate coursework and thesis focused on consumer research and statistics, which helped me learn to interpret & evaluate the quality of peer-reviewed studies.
3. I have my Hair Practitioner certification from the International Association of Trichologists (IAT).

I am *not* a cosmetic chemist and do not have a science PhD.
