"Hydrating hair products" describes hair care products intended to replenish and maintain hair's moisture levels. Think conditioners, hair masks, or leave-in treatments with humectants and emollients that draw in and retain moisture.
Healthy hydration is crucial for hair's elasticity, strength, and shine, preventing breakage and dryness. A pivotal development was the introduction of humectant-rich products in the 1970s, revolutionizing hair care.
