Best suited to people who want a maximum-strength hold for structured, editorial, spiked, or otherwise architectural short-to-medium styles on fine or normal hair — not a light everyday styling gel. It works for both men's and women's short cuts and suits stylists or confident at-home users comfortable handling a very firm-hold acrylic gel.

Hardliner exists for the moments a regular styling gel can't hold — sharp partings, spikes, and other structured or avant-garde shapes that need to survive a full day without collapsing, while the included pintail comb lets you carve those lines precisely as you work the product through.

1. Warm a small amount between the palms and work it through towel-dried hair, focusing on mid-lengths to ends.
2. Use the included steel pintail comb to section hair and cut in sharp partings or spikes as desired.
3. Shape the style with fingers or comb for structured, editorial, or spiked results.
4. Air-dry or blow-dry to set the hold; re-mold with fingers through the day if the style needs a touch-up.

Pros:

• Delivers the highest hold level in Goldwell's StyleSign range, so structured styles hold through a full day
• FlexPROtec complex with UV filters helps protect color and hair from heat- and sun-related fading
• Comes bundled with a steel pintail comb for sectioning and precision styling
• Bamboo shoot extract keeps the strong hold from feeling brittle or overly stiff

Cons:

• Hold level is too strong for soft, natural, or everyday looks and can feel heavy if overapplied on fine hair
• Contains fragrance allergens (linalool, limonene, geraniol, eugenol) and parabens, which may not suit fragrance- or preservative-sensitive scalps
• Best suited to short-to-medium lengths; not designed for long-hair styling
