BioSilk Silk Therapy Hair Serum 12 oz — Lightweight Frizz Smoother & Shine Enhancer

Designed for anyone who wants faster styling and a polished finish, BioSilk Silk Therapy Serum blends a silky formula that layers easily over damp or dry hair. This iconic serum is formulated to improve manageability, impart sheen, and reduce the appearance of flyaways without weighing hair down. It works well as a prepping step before heat styling or as a finishing touch to tame frizz and accentuate natural texture.

How will this serum change my daily styling routine?

Incorporating BioSilk Silk Therapy Serum typically shortens styling time by smoothing the hair cuticle and reducing tangles. Apply a small amount to damp hair to ease combing, or use a drop on dry strands to control frizz and refine shape. The lightweight feel leaves hair soft rather than greasy, so you can layer other products if needed.

• Apply 1–2 pumps on damp hair to detangle and prepare for blow-drying
• Use a tiny amount on dry ends to smooth flyaways and add shine
• Compatible with heat tools as a prepping step (use appropriate heat-protectant routine)

Will this serum work on my hair type—curly, fine, or thick?

BioSilk Silk Therapy Serum is formulated to be versatile across textures and densities. Fine hair benefits from a minimal amount to avoid weighing, while medium to thick hair can use slightly more to manage frizz and define shape. Curly and wavy hair types can apply through mid-lengths and ends to enhance definition and reduce haloing without flattening natural bounce.

• Fine hair: use one small pump concentrated on ends
• Medium hair: distribute 1–2 pumps from mid-lengths to ends
• Thick or curly hair: use 2–3 pumps to control frizz and define curls

How should I apply the 12 oz serum for best results?

Start with a small amount—less is more—and increase gradually until you find the right balance for your hair. Rub the serum between palms and smooth through damp or dry hair, focusing on mid-lengths and ends. For heat styling, allow the product to settle briefly before using a blow dryer or flat iron.

• Dispense sparingly; spread evenly between palms first
• Work from mid-lengths toward ends, avoiding the roots if you have oily scalp
• Reapply a tiny drop on dry hair to tame frizz or add shine as needed

Who is this for: BioSilk Silk Therapy Serum in the 12 oz size is ideal for people who want an easy-to-use finishing and prepping product that enhances shine and manageability. It suits unisex users, salon professionals who need a reliable styling staple, and anyone with medium to long hair seeking smoother, more polished results. If you prefer lightweight serums that layer well with other styling products and want a recognizable classic formula, this product is designed for you.
