The Original Science library
Whether you are new to hair loss or a veteran of the Norwood Scale, this library exists to help you navigate the disparate information and research scattered across the internet. No sponsorships, no affiliations, completely impartial. It is free to read and always will be.
Understanding hair loss
Hair loss is a topic fraught with misinformation and miracle cures, from applying rosemary oil to your scalp (hint: it does not do much) to going all in on a transplant abroad. We want you as well informed as possible, so that when it comes to making a decision you can make the best one for yourself.
Everything here is organised by topic. If you would rather skip the reading and get a plan built around your own genetics, the DNA test and custom topical do exactly that.
