BioSilk Silk Therapy Original

Lightweight leave-in treatment that smooths, strengthens, and adds glassy shine

Silk Therapy Original is BioSilk’s iconic, weightless leave-in treatment that helps tame frizz, seal split ends, and boost softness and shine. The silky formula glides through damp or dry hair to improve manageability and protect against everyday stress—from brushing and heat to humidity—leaving hair sleek, touchable, and luminous.

Why You’ll Love It

• Instant frizz control—smooths cuticle for a polished, flyaway-free finish
• Silk-infused shine—adds a healthy, reflective gloss without heaviness
• Damage protection—helps cushion hair from styling stress
• Split-end help—lightly seals and softens rough ends
• Multi-use—works on damp before blow-dry or dry as a finisher

How to Use

1. Dispense a small amount into palms (start with a pea-size for fine hair).
2. Emulsify and apply from mid-lengths to ends on damp or dry hair.
3. Blow-dry or air-dry and style. Add a drop to dry ends to finish and add shine.

Best For

All hair types seeking smoothness, softness, and shine—especially frizz-prone, dry, or heat-styled hair.

Bonus Benefits

• Weightless feel—no greasy residue
• Enhances slip for easier detangling
• Great as an overnight end-sealer or pre-blowout primer

Pro Tip

Mix a tiny drop with your favorite curl cream or leave-in to boost slip and shine without weighing curls down. For ultra-sleek blowouts, apply before round-brushing and smooth a whisper over flyaways after styling.
