How much should I trim for split ends?

For mild splits, 0.5 cm is usually enough. Moderate splits need 1-2 cm removed. Severe splits with damage up the shaft may need 3-5 cm. The goal is to cut just above where the splitting starts.

How often should I trim to prevent split ends?

Every 8-12 weeks for most hair types. Fine hair may need trims every 6-8 weeks. Curly hair can often go 10-14 weeks. Regular trims prevent splits from travelling up the shaft and causing more breakage.

Can split ends be repaired without cutting?

Split ends cannot be permanently repaired. Bond-building treatments and serums can temporarily seal splits, but the only real solution is to cut above the split. Prevention through heat protection and gentle handling is key.

How We Calculate This

This calculator estimates the ideal trim amount based on split end severity, hair type and growth goals. It balances damage removal with length retention.

How it works

Base trim amounts are set by severity level, then adjusted for hair type and growth goal. Fine hair is slightly more trim-prone while curly hair can retain slightly more length. The maximum trim is capped at 30% of total length.
