BioSilk Silk Therapy Leave-In Hair Treatment 34 oz — Reconstructing, Smoothes & Adds Shine

BioSilk Silk Therapy Original is a lightweight leave-in treatment that rebuilds and smooths hair while adding lasting shine and frizz control.

Formulated with silk proteins, this reconstructing leave-in treatment protects, conditions, and helps detangle strands without weighing hair down. The 34 oz professional-size bottle delivers repeated salon-style results for all hair types, from fine and straight to textured and curly. Sulfate- and paraben-free and cruelty-free, it works as a finishing gloss, daily detangler, and heat-protective booster.

How will BioSilk help my hair feel and look?

BioSilk silk proteins coat the hair shaft to smooth the cuticle, so strands glide together more easily and reflect light for improved shine. Regular use helps reduce the appearance of split ends and frizz while making hair easier to comb and style.

• Creates a silky surface for enhanced shine and manageability
• Reduces tangles to lower breakage during brushing
• Smooths frizz for a sleeker finish
• Leaves hair feeling soft without heaviness

Can I use this on wet and dry hair, and what results should I expect?

Yes—apply BioSilk to damp hair for conditioning and easier detangling, or use a small amount on dry hair to tame flyaways and add shine. On wet hair it supports styling and protects during blow-drying; on dry hair it refreshes texture and smooths the surface.

• Wet application: detangles, primes for heat styling
• Dry application: smooths flyaways and boosts shine
• Works as a finishing gloss after styling
• Safe for daily use on most hair types

Is this safe for colored, chemically treated, or textured hair?

BioSilk is formulated to be gentle—free from sulfates and parabens—and is compatible with colored and chemically treated hair. It provides an extra layer of protection and conditioning for hair that has been lightened, relaxed, or chemically styled, while also benefiting naturally textured hair.

• Color-safe ingredients that do not contain sulfates or parabens
• Helps protect chemically treated cuticles from moisture loss
• Enhances manageability for textured and curly patterns
• Can be incorporated into a professional haircare routine

How much should I use and how often?

A little goes a long way: start with a dime- to nickel-sized amount for short to medium hair, and a bit more for long or coarse hair. Use after shampooing and conditioning on damp hair, or sparingly on dry hair to smooth and refresh; daily use is fine for most people seeking consistent conditioning and shine.

• Short hair: very small amount for shine and control
• Medium/long hair: distribute evenly from mid-lengths to ends
• Coarse or thick hair: increase slightly to ensure coverage
• Reapply lightly on dry hair for mid-day touch-ups

Who this is for: BioSilk Silk Therapy Original 34 oz suits anyone who wants salon-style smoothing, easier detangling, and added shine without heavy residue. It's especially useful for people with frizz-prone, chemically processed, or tangled hair, and for stylists or households that prefer a large, economical size for repeated professional results.
