BioSilk Silk Therapy Original BSST2A Leave-In Hair Treatment, 2.26 Oz
Product description
Some hair routines center on rinse-out conditioning, others call for a leave-in treatment that can smooth and add shine as you style. BioSilk Silk Therapy Original is designed for the second approach, with silk proteins in a lightweight formula. Want a single step for detangling, conditioning, and shine? It can be used on wet or dry hair.
Key specifications

- Name: Silk Therapy Original
- Type: Leave-in hair treatment
- Size: 2.26 oz
- Formula: Sulfate-free, paraben-free, and cruelty-free


The treatment helps smooth strands, reduce frizz, and improve shine while helping protect hair from heat and environmental stress. Its silk-protein formula is intended to reconstruct and strengthen damaged hair and help prevent split ends. That makes it useful as part of a styling routine focused on a smoother, more polished finish, rather than as a rinse-out conditioner. The formula is described for straight, wavy, curly, fine, and textured hair.

Getting the most from it
Shake well, then place a small amount in your palms and apply through the hair from scalp to ends. Use it on damp hair before styling for conditioning, detangling, and smoothing, or apply to dry hair when you want to add shine and manage flyaways. Start with a small amount and distribute it through the strands, the treatment is designed to work without a heavy feel. Its leave-in format keeps it in the routine after application instead of adding a rinse-out step.



Buyers often describe their hair as feeling softer and silkier and looking shinier after use. Some also mention fragrance and frizz control as positives, including for fine hair. Feedback about the compact bottle is mixed: some appreciate its handy size, while others expected a larger bottle. These are individual impressions, so results and preferences can vary.
Everyday use

For a practical styling routine, apply a small amount to damp hair after washing, then work it through before styling. On dry hair, use it to smooth the finish and add shine. Because it can be used on either wet or dry hair, the treatment fits both post-wash care and touch-ups between washes. It offers a different kind of care from a rinse-out conditioner: an applied-and-left-in step that supports smoothness and shine while you style.


What to clarify

How do you apply Silk Therapy Original? Shake well, rub a small amount between your palms, and apply it through the hair from scalp to ends. It can be used on wet or dry hair.
Is it intended for a particular hair texture? The formula is described as suitable for straight, wavy, curly, fine, and textured hair.

What can it help with during styling? It helps condition, detangle, smooth, and add shine, while helping reduce frizz and protect hair from heat and environmental stress.
Final verdict
