Detailed answer

Split ends are caused by damage to the hair shaft and are not related to allergies to skincare products. Allergies to skincare products typically present as skin reactions such as itching, redness, or rashes but do not directly affect the hair. Split ends occur when the protective outer layer of the hair strand is damaged or frayed due to factors such as heat styling, excessive brushing, chemical treatments, or environmental factors. To prevent and treat split ends, it is important to minimize hair damage by using gentle hair care practices, avoiding excessive heat and chemical treatments, and regularly trimming the hair. If you suspect an allergic reaction to a skincare product, discontinue its use and consult with a healthcare professional or dermatologist.
