Haarkur

Haarkur is a term used in German-speaking contexts to denote a hair treatment designed to improve the condition of the hair. It usually refers to a deep conditioning mask that is applied after washing and left to work before rinsing. While not a medical therapy, a haarkur is part of cosmetic daily or weekly routines intended to restore moisture, add protein, or protect color and heat damage.

Types and formulations vary. Moisture- and emollient-rich masks typically contain oils (argan, coconut), butters (shea), and humectants (glycerin). Protein-based formulas may include hydrolyzed keratin or wheat proteins to strengthen strands. There are also color-protecting and repair-focused variants, plus overnight or oil-based haarkuren for intensive treatment.

Application generally involves washing the hair, towel-drying to remove excess water, applying the product to mid-lengths and ends (and sometimes the scalp, depending on the product), detangling, leaving the mask in for a recommended time (often 5–20 minutes, longer for intensive treatments), and rinsing thoroughly. Frequency ranges from weekly to biweekly, depending on hair type and needs; overuse can lead to buildup or weighed-down hair.

Safety and suitability considerations include patch testing for allergies, avoiding eye contact, and selecting formulas appropriate for hair type (dry, oily, color-treated, or chemically relaxed). Haarkur complements regular conditioner and can be part of salon treatments for damaged or severely processed hair.
