Sealing Split Ends and Preventing New Ones
Split ends form when the protective outer cuticle of a hair strand wears away, usually from heat, mechanical friction or chemical processing, exposing and eventually splitting the inner cortex. No product can permanently mend an already-split strand, since the damage is structural, but sealing treatments coat the exposed area to reduce visible splitting and prevent it worsening until a trim is possible.
What is in this collection
Osmo's Wonder 10 range and Finishing Creme both work as sealing, multi-benefit treatments that smooth the cuticle and reduce the appearance of splitting, while Osmo Thermal Defense adds a preventive layer of heat protection to reduce future damage. Crazy Color's Bond Recovery Treatment takes a more intensive approach for chemically processed hair prone to splitting from colour or bleach work.
Brands in this range
Osmo and Crazy Color anchor this collection, spanning everyday sealing sprays and creams through to more intensive bond-recovery treatments for chemically stressed hair.
Zilion is an official NZ stockist
Sealing and bond-recovery formulas rely on specific film-forming and repair ingredients to work as intended, and Zilion sources both Osmo and Crazy Color through official distribution to keep that formulation reliable.
Why customers keep coming back
Split ends are an ongoing maintenance issue rather than a one-time fix, so customers tend to combine a sealing treatment with regular trims and heat protection rather than relying on any single product alone.

Frequently Asked Questions
Can split ends actually be repaired, or do they need to be cut off?
Split ends cannot be permanently mended once the strand has separated, though sealing treatments can smooth the area and prevent it worsening until your next trim.
What causes split ends in the first place?
Heat styling, chemical treatments, aggressive brushing and general wear over time all wear down the protective cuticle, eventually causing the strand to split.
How often should I trim my hair to prevent split ends?
Every six to eight weeks is generally recommended, though this varies depending on hair type, styling habits and how quickly damage tends to occur.
Will Osmo Wonder 10 stop my hair from splitting further?
It seals and smooths the cuticle to reduce further splitting and improve appearance, though it works best alongside regular trims rather than replacing them.
Is Crazy Color Bond Recovery Treatment only for coloured hair?
It is particularly beneficial for chemically processed or bleached hair, though it also supports general strand strength for anyone prone to splitting.
Can heat protectant prevent split ends from forming?
Yes, reducing heat damage is one of the most effective ways to prevent new splits from developing over time.
Why do my ends split even though I use conditioner every wash?
Standard conditioner smooths the surface but does not specifically target split ends, which need a dedicated sealing treatment for visible improvement.
Is it normal to have split ends even with healthy-looking hair?
Yes, split ends often start small and invisible before becoming more noticeable, especially towards the ends of longer hair.
Can brushing my hair too much cause split ends?
Yes, excessive or aggressive brushing creates friction that wears down the cuticle and contributes to splitting over time.
Should I apply sealing treatments to wet or dry hair?
This varies by product, with some designed for damp hair before styling and others formulated for use on dry hair as a finishing step.
Does hair grow slower if I have a lot of split ends?
Split ends do not affect the growth rate at the scalp, though untreated splitting can travel up the strand and lead to more breakage over time.
Can I use a split-end sealer alongside my regular shampoo and conditioner?
Yes, sealing treatments are typically used as an additional step, applied after conditioning or as a leave-in finishing product.
Is Osmo Finishing Creme suitable for fine hair prone to splitting?
Yes, though fine hair should use a smaller amount to avoid weighing the hair down while still getting the sealing benefit.
Can tying my hair up tightly cause split ends?
Yes, repeated tension from tight hairstyles can stress and eventually split the hair shaft, particularly where hair ties sit.
Will using these products mean I need fewer trims?
They can help extend the time between trims by reducing visible splitting, though regular trims remain the only way to fully remove existing splits.
Can chemically relaxed or permed hair be more prone to splitting?
Yes, chemical processing weakens the hair's internal structure, making split ends more likely without a supportive repair routine.
Is it worth using a split-end product if I already trim regularly?
Yes, sealing treatments help protect ends between trims and can extend how long your hair looks healthy after a cut.
Can men with shorter hair still get split ends?
Yes, split ends can occur on any hair length, though they are often more visible and problematic on longer hair.
Does dry weather make split ends worse?
Yes, dry air can further dehydrate already vulnerable ends, making them more prone to splitting.
How does Zilion guarantee these split-end treatments are genuine?
Zilion is an official stockist for Osmo and Crazy Color, sourcing every product directly rather than through resellers.
