## Frequently asked questions

### Can split ends be repaired without cutting?

No. Products can temporarily seal a split's appearance and reduce friction, but the shaft is physically frayed and nothing rejoins it permanently. Cutting above the split is the only actual fix, which is why prevention focuses on slowing how fast new splits form.

### How far above a split should I cut?

A few millimetres above the visible top of the split, since fraying extends slightly beyond what is easy to see. Cutting exactly at the visible end of the split usually leaves damaged fibre that splits again quickly.

### How often should I do search and destroy?

Check monthly and clear what you find in short sessions. If each session finds dramatically more splits than the last, or the ends feel thin and rough overall, that is the signal to switch to a proper trim instead of more hunting.

### Why do my ends split faster than the rest of my hair?

They are the oldest hair you own, with the longest history of washing, heat, sun, and friction, and the cuticle there is the most worn. Ends are also farthest from the scalp's oils. Faster splitting at the ends is normal; the management is protection plus regular removal.
