Winter weather makes my dry scalp even more sensitive, and this Briogeo Scalp Revival Scalp Therapy Essentials Value Set ($85) packs an exfoliating shampoo and cool conditioner that I know will get things sorted. Plus, this set — valued at $126 — adds a massager to work those products in, plus a charcoal-and-tea-tree treatment to keep things balanced in the future, too.
