Does hair dyeing cause hair loss?
Generally, dyeing hair does not cause hair loss. However, frequent dyeing that irritates the scalp may lead to hair shedding. The extent depends on how often the hair is dyed. Detailed explanations are as follows:
1. No
Hair dyeing uses plant-based and chemical pigments to color hair as desired. It can effectively cover gray hairs and enhance one's appearance, making it a common cosmetic practice. If hair dyeing is done infrequently, the hair is typically unaffected, the hair follicles remain undamaged, and hair loss does not occur.
2. Yes
If hair is dyed frequently, the oxidation of ammonia and hydrogen peroxide in hair dyes can severely deplete the proteins within the hair, leading to dryness and the formation of numerous pores. Additionally, hair dyes may irritate the scalp and damage hair follicles, resulting in hair loss.
Besides, individuals with sensitive skin may also experience hair loss after dyeing their hair. Therefore, a skin patch test should be performed before dyeing to check for allergic reactions. Only if no allergy occurs should hair dyeing proceed. It is advisable to avoid excessively frequent dyeing. Regular scalp massage in daily life can promote blood circulation and contribute to healthier hair.
