BioSilk Silk Therapy leave-in hair treatment 12 oz — lightweight reconstructing serum for shine & split-end repair

BioSilk Silk Therapy Original is a lightweight leave-in serum that repairs and smooths hair by filling cuticle gaps, adds glossy shine, and helps reduce split ends without weighing hair down.

Formulated for everyday use on all hair types, this 12 oz (355 ml) leave-in reconstructing treatment combines silk proteins and gentle ingredients to improve hair texture and manageability. It’s sulfate- and paraben-free and cruelty-free, designed to be applied to wet or dry hair to detangle, protect, and boost shine while working to rebuild stressed or chemically treated strands.

How does BioSilk Silk Therapy help damaged or processed hair?

The serum deposits silk proteins that adhere to the hair shaft to fill microscopic gaps in the cuticle, improving strength and reducing breakage. Regular use helps create the appearance of smoother, more uniform strands that reflect light better.

• Reconstructs weakened areas of the cuticle for improved resilience
• Helps reduce split ends and lessen further breakage
• Enhances shine for a healthier-looking finish

Can I use this product on my fine or oily hair without it becoming greasy?

Yes — the formula is specifically formulated to be weightless, so a small amount smooths and protects without heavy residue. Start with a pea-sized amount and focus on mid-lengths to ends to avoid buildup at the roots.

• Lightweight texture suitable for fine strands
• Dose sparingly for oily or limp hair to maintain volume
• Works on wet or dry hair for flexible styling use

How should I apply BioSilk Silk Therapy for best results?

Apply a small amount to towel-dried hair to detangle and seal the cuticle before styling, or smooth a tiny amount over dry hair for shine and frizz control. Use it alone or before heat styling to help protect strands from thermal stress and environmental exposure.

• Rub a small drop between palms, then distribute mid-lengths to ends
• Use on damp hair prior to blow-drying, or lightly on dry hair to tame frizz
• Reapply sparingly — buildup is avoidable with minimal amounts

Is BioSilk Silk Therapy safe for colored and textured hair?

Its gentle, sulfate‑ and paraben‑free formula is compatible with color-treated, permed, chemically relaxed, curly, and textured hair. Because it helps seal the cuticle and reduces friction, it can improve manageability across a wide range of textures.

• Safe to use on color- or chemically-treated hair
• Improves detangling for curly and textured types
• Cruelty-free formula suitable for regular maintenance

Who is this for: BioSilk Silk Therapy Original is ideal for anyone seeking an everyday, multitasking leave-in treatment — from those with damaged or color-treated hair to people wanting a light finishing serum for shine and frizz control. If you want a simple, versatile product that strengthens, smooths, and polishes hair without harsh sulfates or parabens, this 12 oz bottle provides salon-tested benefits in a user-friendly form.
