Quick answer
No product repairs a split end permanently. Products smooth and prevent; scissors are the only cure. Here is how to slow it down.

A split end is a structural break. Serums and masks smooth the cuticle and make splits less visible, but nothing glues them back. Trimming is the only removal.
1. Trim every 8–12 weeks
A split travels upward if left. Small regular trims cost less length than one big cut later.
2. Seal ends daily in winter
A little serum on the last few inches is the highest-return habit.
3. Reduce friction
Rough towel-drying and tight ties cause most mechanical damage.
4. Protein and moisture in balance
Too much protein makes hair brittle; too little makes it limp. Alternate.
