What is a common reason for hair breakage?

Hair breakage often occurs due to over-processing or excessive heat exposure. When hair undergoes chemical treatments like coloring, perming, or relaxing, the structure of the hair can be compromised. This can lead to weakened bonds within the hair shaft, making it more susceptible to breakage. Similarly, the use of high-heat styling tools like straighteners, curling irons, and blow dryers can strip moisture from the hair and damage its protective outer layer. This results in hair becoming dry and brittle, further increasing the likelihood of breakage.

While lack of moisture, improper brushing, and allergic reactions can contribute to various hair issues, they are not as direct in causing breakage as the effects of over-processing and heat damage. Lack of moisture can lead to dryness, which may ultimately result in breakage, but it is not the immediate cause. Improper brushing can lead to split ends or tangling but does not impact the overall integrity of the hair as significantly. Allergic reactions can cause irritation and hair health issues, yet they typically do not lead to breakage as a primary concern. Therefore, the primary reason for hair breakage is rooted in over-processing and the application of excessive heat, which weaken and damage the hair structure.
