A hair-care regimen can vary from zero to six products a day. While previous generations may have had nothing and relied solely on grooming, in an increasingly competitive society, the prolonged wearing of unwashed, matted, and neglected hair is considered unusual at the very least.
In some developed societies, bar soaps for washing the scalp, particularly among men, are still common. These harsh anionic surfactant systems are not just poor cleansers, but also lead to extensive calcium salt buildup in the hair and reduced grooming capability.
Daily shampooing alone can be harmless to the hair shaft, and in itself can improve the ability to groom and style. Haircare products, in comparison to skin care are inexpensive and ubiquitous.
