Split ends, medically known as trichoptilosis, are a prevalent hair concern resulting from damage to the hair's outer protective layer, the cuticle. Dermatologist Dr. Shivani Yadav, founder of Skin Avenue Clinic, explains that common causes include excessive heat styling, chemical treatments, over-washing, and environmental factors like pollution and sun exposure. While many products claim to 'repair' split ends, Dr. Yadav clarifies that they can only be temporarily smoothed, as once a hair strand splits, it cannot be permanently fixed. The most effective solution is regular trimming to prevent further damage. To manage split ends, she recommends using gentle, sulfate-free shampoos, deep conditioning masks, and heat protectants when styling. Additionally, trimming hair every 6–8 weeks and protecting hair from environmental stressors are crucial for prevention. A balanced diet rich in protein, vitamins, and minerals, along with proper hydration and stress management, also supports overall hair health. Dr. Yadav concludes that healthy hair requires consistent care and timely interventions.
