Probably the most comprehensive blog out there about comfort shoes.

Recovering Shopaholic

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.

Science-y Hair Care Blog

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.
