Overview
Home manicure tables are where Sally Hansen Diamond Strength does its job, brushing on as a glossy strengthening layer that protects weak nails. Wear it alone or as a base under polish.
Splitting, breaking nails get a protective hardening coat with a glossy finish in one bottle. The listing is sparse, with conflicting volumes and no ingredient list, so you rely on the brand rather than details.
Who it's for
Brittle, peeling nails that need protection between manicures fit this treatment. People who want color or a gel system should choose a different product.
Pros and cons
- Strengthens and protects nails
- Glossy finish alone or under color
- Brand claims protection for days
- Volume figures conflict in the listing
- Ingredients not listed
- Needs reapplying as it wears
Performance notes
Protection comes from a hard film over the nail plate that resists bending, which is what reduces breaks and splits. How long it lasts depends on wear and water exposure. Reapplying maintains the layer.
