L LUSETA Biotin Hair Growth Serum with Collagen — 3.38 fl oz Lightweight Oil for Thicker, Frizz-Reduced Hair

This lightweight serum combines biotin and collagen with conditioning oils to target the look and manageability of thin, stressed hair. Designed for daily use, the formula aims to protect against breakage, smooth flyaways and add dimension so hair appears fuller without weighing it down. It’s sulfate- and paraben-free and safe to use with color-treated hair.

How does this serum improve the feel and appearance of thin or damaged hair?

The serum works as a fortifying leave-in: collagen and biotin support the hair surface while argan oil hydrates and reduces frizz. Regular, small applications help reduce the appearance of breakage and add slip for easier styling. Over time hair looks smoother and gains a thicker-looking profile.

• Biotin and collagen to strengthen and add body
• Argan oil for hydration, shine and reduced dryness
• Lightweight texture that won’t leave heavy residue
• Daily use promotes manageability and softer strands

Will this serum protect my hair from environmental damage?

The formulation forms a protective layer around each strand to help shield against pollutants and UV exposure. This barrier helps minimize mechanical wear and free-radical stress that can accelerate breakage or dullness. Use as part of a routine to maintain healthier-looking hair between washes.

• Protective barrier to reduce pollution and UV effects
• Helps lock in moisture to prevent dryness
• Reduces split end visibility and surface roughness

How should I apply the serum for best results?

Dispense a small amount into your palms and distribute evenly through damp or dry hair, focusing on mid-lengths and ends. For thicker or longer hair, use slightly more; for fine hair, use a pea-sized amount to avoid weighing hair down. Can be combined with L LUSETA biotin shampoo and conditioner for a complementary routine.

• Start with 1–2 drops for short/fine hair; increase as needed
• Apply primarily to lengths and ends, avoid heavy roots
• Use daily or as a styling finishing oil for shine

Is this product safe for color-treated or sensitive hair?

Yes — the serum is formulated without sulfates and parabens and is labeled color-safe, making it suitable for chemically treated hair. Its gentle conditioning oils help restore softness and reduce tangles without stripping dyes. If you have scalp sensitivities, patch-test before regular use.

• Sulfate- and paraben-free, safe for color-treated hair
• Non-greasy oil blend to improve softness and manageability
• Patch-test recommendation for sensitive scalps
