Numerous factors can contribute to weakened hair, leading to its splitting or snapping. These factors can be categorized into mechanical, chemical, and environmental stressors, as well as nutritional deficiencies and underlying health conditions. For example, roughly handling hair through tight styling or aggressive brushing can cause physical damage. Chemical processes like bleaching, perming, or relaxing alter the hair’s structure, making it more susceptible to breakage. Environmental factors, such as exposure to sun, wind, and dry air, can also dehydrate and weaken hair.
Understanding the various causes of compromised hair integrity is crucial for maintaining its health and appearance. Historically, hair care practices have evolved significantly, moving from simple cleansing and grooming techniques to complex chemical treatments and specialized products. This evolution highlights the growing awareness of the diverse factors influencing hair health and the importance of proactive preventative measures.
