BioSilk Silk Therapy Leave-In Hair Treatment 2.26 oz — Reconstructing Silk Protein, Lightweight Shine & Frizz Control

BioSilk Silk Therapy Original is a lightweight, leave-in silk protein treatment that repairs, smooths and protects hair while adding long-lasting shine.

Formulated to work on straight, wavy, curly and textured hair, this 2.26 oz reconstructing leave-in delivers silk-derived proteins to help mend damage, reduce frizz and improve manageability without weighing strands down. Sulfate- and paraben-free and cruelty-free, it can be applied to wet or dry hair as a detangler, heat protectant and shine enhancer.

How does BioSilk help damaged or chemically treated hair?

BioSilk Silk Therapy deposits silk proteins and lightweight conditioning agents that temporarily fill and smooth the hair surface, reducing the appearance of split ends and stiffness from chemical services. Regular use helps hair look healthier and feel softer, while providing a smoother canvas for styling.

• Reconstructing silk proteins that smooth cuticle irregularities
• Helps reduce visible split ends and brittleness
• Improves comb-through to minimize breakage during detangling

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

Yes — the formula is designed to be weightless and non-greasy, making it suitable for fine hair when used sparingly. Apply a pea-sized amount to mid-lengths and ends; avoid the scalp if you worry about oiliness. For oily types, focus application on the ends or use it as a finishing polish after styling.

• Lightweight texture that won’t weigh down strands
• Small amounts improve shine without greasiness
• Works as a finishing serum or a leave-in detangler on wet hair

How do I add BioSilk to my daily routine and does it protect from heat?

Use BioSilk on damp hair before blow-drying to detangle and shield strands from styling heat, or smooth a tiny amount over dry hair to tame flyaways and boost shine. The product offers light thermal protection through its conditioning layer and helps reduce friction from tools, but it’s not a standalone high-heat barrier — pair with a dedicated heat protectant for intense styling.

• Apply to towel-dried hair before blow-drying for smoother styling
• Use a small amount on dry hair to finish and control frizz
• Complements stronger heat-protection sprays for high-temperature tools

What makes BioSilk suitable for different hair textures and routines?

The formula balances conditioning power with a light feel so it can support a wide range of textures — from fine, straight strands to denser curls — without requiring different versions. It detangles, enhances shine and helps protect against environmental stressors, making it a versatile addition whether you wash daily, style frequently, or maintain natural textures.

• Multi-purpose use: detangling, conditioning, smoothing and shine
• Sulfate- and paraben-free, cruelty-free formulation suitable for many routines
• Can be used on wet or dry hair to adapt to styling needs

Who is this for: BioSilk Silk Therapy Original is ideal for anyone seeking a lightweight, leave-in reconstructing treatment that improves shine, smooths frizz and helps protect hair from everyday styling and environmental wear. It’s a convenient option for people with damaged, chemically treated, textured, or fine hair who want an easy-to-use product that adds softness and manageability without heaviness.
