Probably the most comprehensive blog out there about comfort shoes.
A useful resource for anyone interested (personally or abstractly) in the psychology of shopping addictions, and useful too for anyone looking to cut down their wardrobe. Very thoughtful.
Blog on the science of hair care, especially for people with curly hair.
Really excellent science-based skincare blog. Unfortunately, hasn’t been updated since October 2014, but has a lot of really useful info in the archives.
