Consumers dedicate an impressive amount of time over the course of a lifetime to cleaning and styling hair, and managing its luster and sensorial appeal, but many daily treatments can damage the hair—notably harsh shampoos, heavy brushing and combing, as well as frequent exposure to chemicals, e.g., from perms, bleaching and dyes.
Moreover, environmental stressors including excessive exposure to sun and salt water, very dry or humid atmospheres, and absorption of city pollutants pose risks to the integrity of hair structure. Finally, aging phenomena contribute to decreases in the speed of hair renewal, weakening the keratin structures and producing thinner and less structured hair shafts.
Many approaches can be used to fight these phenomena. These include: repairing hair structure to recover as much of its integrity as possible; treating hair with specified ingredients to increase its strength and resilience; and directly acting on the scalp to promote hair growth. The practical application of these strategies is described here.
The Right Vehicles
Before delving into active solutions, it is important to consider that any hair care treatment must take into account a few major factors. The appearance of the treated hair must be pleasant and shiny, and its feel soft and manageable. The amount of residue left on the scalp and the hair should be negligible and non-noticeable. Also, for leave-on products, the drying time should be fairly fast. In other words, any vehicle for hair treatments should provide a perceivable hair conditioning effect without any stickiness or excessive build-up.
