Split ends cannot be entirely prevented without trimming, but there are methods to minimize their formation and maintain healthy, long hair.
Brush hair gently from the ends, use a microfiber towel to absorb water, and wear loose braids or buns to avoid breaking.
Furthermore, trims should be done every 6-8 weeks to remove split ends before they go up the hair shaft without removing too much.
Reduce heat styling methods like blow drying, straightening, or curling, apply heat protectant spray, and adjust temperature settings if needed.
Deep treat dry hair on a regular basis, paying special attention to the ends, which are more prone to splitting.
