Hair Theory – Perfumed Hair Serum

A featherlight finishing serum that smooths, protects, and leaves your hair carrying a cloud of your favourite fragrance all day. Not a perfume spray. Not a styling product. A serum that does both. Each scent is our own impression of an iconic fragrance.

Key Benefits

• Long-lasting fragrance that clings gently to hair — never overpowering
• Lightweight formula — no grease, no weight, no residue
• Adds instant softness and mirror-like shine
• Protective finish reduces friction, breakage, and static
• Works on all hair types — dry, damp, or styled

Choose Your Scent

• Gucci Flora — Fresh peony and soft rose. Light, feminine, effortlessly elegant.
• Le Labo Another 13 — Ambrette and warm musk. Intimate, modern, quietly addictive.
• Dior Sauvage — Bergamot and ambroxan. Bold, confident, magnetic.
• Le Labo Santal 33 — Sandalwood, leather, and cedar. Warm, earthy, effortlessly cool.
• Warm Vanilla — Vanilla bean, amber, and creamy musk. Cozy, comforting, effortlessly inviting.
• Green Tea — Fresh green tea, dewy cucumber, and soft citrus. Clean, airy, quietly refreshing.

How To Use

On dry hair (anytime): 2–3 drops into palms, apply from mid-length to ends, style as usual. Fragrance activates with body heat and movement.

On damp hair (post-wash): Apply after washing on damp hair for an extra layer of fragrance and finish as hair dries.

Tip: Use as a standalone finishing product, or layer it as your Step 02 in the Hair Theory protocol.
