BioSilk Silk Therapy Original Leave-In Hair Treatment 12 oz — Lightweight Shine & Split-End Protection

BioSilk Silk Therapy Original is a lightweight, leave-in silk protein treatment that smooths, adds shine, and helps fortify hair to reduce split ends.

Formulated for everyday use, this 12 oz (355 ml) reconstructing serum layers a silk-protein complex onto strands to fill and smooth the cuticle without weighing hair down. It works on wet or dry hair to detangle, boost luster, and provide a protective finish that helps hair look healthier and more manageable. Sulfate- and paraben-free and cruelty-free, the formula suits a wide range of textures from fine and straight to thick and curly.

How does BioSilk Silk Therapy Original improve hair texture?

The silk-derived proteins in this leave-in concentrate bind to the hair surface, evening out rough cuticle edges so strands feel smoother to the touch. Over time, regular use creates a sleeker appearance and reduces the friction that contributes to frizz and tangling.

• Silk proteins help fill and level cuticle irregularities.
• Lightweight formula avoids limp or greasy residue.
• Use after washing or on dry hair to smooth and control flyaways.

Can I use this product on colored or chemically treated hair?

Yes — the gentle, preservative-conscious formula is compatible with color- and chemically treated hair. It helps manage compromised strands by adding conditioning and shine without harsh sulfates or parabens that can strip treatment longevity.

• Sulfate-free and paraben-free for milder maintenance of treated hair.
• Helps reduce the appearance of split ends and improve comb-through ease.
• Safe for routine application to maintain softness and gloss.

How do I apply Silk Therapy for the best results?

Dispense a small amount into your palms and work through mid-lengths to ends; use sparingly at the roots to avoid buildup. Apply to towel-dried hair before styling to detangle and protect, or smooth a tiny amount over dry hair to tame flyaways and boost shine.

• Start with a pea-sized amount for short or fine hair; increase as needed for thicker lengths.
• Can be used before heat styling to improve manageability and finish.
• Reapply a little to dry areas to refresh shine between washes.

What benefits should I expect with continued use?

Regular application helps hair look more polished and resilient: strands appear smoother, reflect more light, and become easier to comb. While it’s not a permanent repair, the reconstructing effects of silk proteins reduce the visual signs of damage and make everyday styling simpler.

• Improved surface smoothness and visible shine.
• Reduced birdnesting and fewer tangles when brushing.
• Helps minimize split ends’ appearance and control frizz.

Who is this for: BioSilk Silk Therapy Original is designed for anyone seeking a lightweight, versatile leave-in treatment — ideal for people with colored, heat-styled, or naturally textured hair who want smoother, shinier-looking strands without heavy silicones or sulfates. It’s a practical choice for daily grooming, post-color maintenance, or as part of a styling routine to enhance gloss and manageability.
