Goldie Locks Signature Hair Serum — 3.4 fl oz Anti-Frizz, Lightweight Shine & Color- and Extension-Safe

Goldie Locks Signature Hair Serum is a lightweight, anti-frizz finishing and styling serum that tames flyaways, boosts shine, and protects color and extensions without weighing hair down.

This concentrated serum blends biotin with a botanical mix of marula oil, white truffle and vanilla bean to hydrate, smooth and add luminous sheen. Formulated protein-free and free of sulfates, parabens, phthalates and DMDM hydantoin, the serum is safe for color-treated hair and extensions while offering heat and UV protection. Its tropical citrus scent refreshes without overpowering, and the texture absorbs quickly to leave hair touchable, not greasy.

How does this serum control frizz and humidity?

The serum creates a lightweight surface layer that smooths cuticles and reduces static, which helps hair resist humidity-driven frizz. Instead of heavy silicones, the formulation uses nourishing oils and a conditioning blend that seals in moisture and keeps hair looking sleek through changing conditions.

• Lightweight oils smooth the hair shaft for immediate frizz reduction
• Cuticle-smoothing action helps hair remain sleek in humid environments
• Leaves no sticky residue so hair stays touchable and natural

Can I use the serum on color-treated hair and extensions?

Yes—this serum is designed to be gentle on enhanced hair, safe for both color-treated strands and most extensions. It omits proteins and harsh preservatives that can compromise treated hair, while adding conditioning and protective benefits that extend style longevity.

• Protein-free formula reduces the risk of buildup on treated hair
• Color-safe and extension-friendly ingredients maintain bond integrity
• Sulfate- and paraben-free to protect color vibrancy and extension materials

When should I apply it: before styling, after styling, or both?

The serum is versatile—use a small amount on damp hair as a heat-styling aid, or smooth over dry hair to refresh and seal shine. Applied before heat, it helps tools glide and improves manageability; applied after styling, it polishes the finish and controls flyaways without flattening volume.

• Damp hair: apply a pea-sized amount to mid-lengths and ends before blow-drying or flat-ironing
• Dry hair: smooth a tiny drop over surfaces to tame frizz and boost shine
• Use sparingly on fine hair to avoid weighing strands down

What are the key nourishing ingredients and sensory notes?

The formula combines biotin to support the appearance of fuller-looking strands with marula oil, white truffle and vanilla bean for hydration and gloss. Ginseng aids manageability, while a light tropical citrus fragrance leaves hair smelling fresh without being cloying.

• Biotin for the look of denser, more resilient hair
• Marula oil and white truffle for concentrated nourishment and shine
• Ginseng for smoother handling and a subtle tropical citrus scent

Who is this for: Goldie Locks Signature Hair Serum is ideal for anyone seeking a non-greasy finishing product that tames frizz, adds shine and protects color-treated or extension-enhanced hair. It's a good fit for fine to medium hair that needs light conditioning without heaviness, and for people who want flexible use—pre-styling protection, post-styling polish, or quick touch-ups during the day. If you prefer clean, vegan formulas without sulfates, parabens, or proteins and value a salon-quality finish from a compact 3.4 fl oz bottle, this serum offers a multi-use solution to simplify daily styling routines.
