BioSilk Silk Therapy Original Leave-In Hair Treatment 2.26 oz — Smooths & Adds Shine

BioSilk Silk Therapy Original is a lightweight, leave-in silk protein treatment designed to smooth, strengthen and add shine to all hair types without weighing strands down.

Designed by BioSilk, this 2.26 oz bottle delivers a concentrated silk-protein formula that detangles, reduces frizz and helps protect hair from heat and daily stressors. It’s free of sulfates and parabens and formulated to be cruelty-free, making it a simple daily step to improve manageability and surface appearance for straight, wavy, curly or textured hair.

How does BioSilk Silk Therapy help frizzy or unruly hair?

The silk proteins in this leave-in treatment smooth the hair cuticle, which reduces surface friction and the appearance of frizz. Applied to damp or dry hair, it helps strands lay flatter for a sleeker finish while improving shine and manageability.

• Silk proteins smooth cuticles for less frizz and flyaways
• Lightweight texture avoids buildup on fine or oily hair
• Works on damp hair as a styling primer or on dry hair for quick touch-ups

Can this product help repair damaged or split ends?

BioSilk Silk Therapy supports the look and feel of damage‑prone hair by reinforcing and coating strands, which can make split ends appear less noticeable and hair feel stronger. While it doesn’t replace a trim, regular use improves surface condition and resilience against daily styling stress.

• Reconstructing silk proteins help improve strand texture
• Regular application minimizes the visual impact of split ends
• Protects hair from heat styling when used prior to blow-drying or flat-ironing

How should I use it for best results on different hair types?

Use a few drops on damp hair to detangle and prime for styling, or smooth a light amount over dry lengths to tame flyaways and boost shine. Adjust the amount: a pea-sized drop for short or fine hair, more for long or coarse textures, concentrating on mid-lengths and ends.

• Damp hair: apply evenly before styling to detangle and protect
• Dry hair: use sparingly for shine and to control frizz
• Fine hair: use minimal product to avoid heaviness; thicker hair can use additional drops

Is BioSilk Silk Therapy Original safe for color-treated or chemically processed hair?

Formulated without sulfates and parabens and created to be gentle, this leave-in treatment is compatible with color-treated and chemically processed hair. It provides conditioning and protective benefits that help maintain appearance and manageability between salon visits.

• Sulfate- and paraben-free, suitable for treated hair
• Helps reduce breakage and improve surface shine after coloring or chemical services
• Can be used daily as part of a maintenance routine
