Goldwell StyleSign Straightening Balm is a color-safe, vegan heat-protective balm that smooths and straightens medium to coarse hair for up to 72 hours while reducing breakage.

This lightweight-to-rich balm combines Marine Bamboo with a color-protecting formula to tame frizz, add glossy shine and shield hair from heat up to 230°C / 446°F. Designed for use with a hairdryer and, when needed, a flat iron, it helps create long-lasting straight styles and reduces mechanical stress during styling. The product is dermatologically tested, free from sulfates, mineral oil and alcohol, and formulated without animal-derived ingredients.

How does this balm keep hair straight and smooth for days?

The balm forms a smoothing layer that locks hair strands into place, resisting humidity and frizz so styles remain straighter for extended periods. It also boosts surface shine for a sleek, polished finish.

• Provides up to 72 hours of straightness for medium to coarse hair.
• High shine level that visibly enhances smoothness.
• Fights humidity and frizz to preserve the style outdoors and in damp conditions.

Will it protect my hair while I use heat tools?

The formula includes protective ingredients that help guard hair against damage from blow-dryers and flat irons up to 230°C / 446°F. It’s also shown to reduce hair breakage during thermal styling when used as directed.

• Heat protection rated up to 230°C / 446°F for safer high-temperature styling.
• Reduces hair breakage—improves strand resilience during styling.
• Works with both blow-drying and flat-ironing techniques for best results.

How do I use the balm for the smoothest, longest-lasting results?

Apply the balm to towel-dried hair, distributing evenly from roots to ends, then blow-dry to set the smoothing effect. If you need extra sleekness, follow with a flat iron on dry hair, working in small sections for consistent results.

• Work a small amount through towel-dried hair for even coverage.
• Blow-dry to activate the straightening and protective properties.
• Finish with a flat iron on dry hair for ultra-straight styles when required.
