VITAMINS hair cosmetics Keratin Hair Mask 3.4 fl oz — Protein Repair Deep Conditioner for Dry, Damaged & Frizzy Hair

VITAMINS hair cosmetics Keratin Hair Mask is a concentrated protein treatment that restores strength, reduces frizz, and delivers deep hydration to dry, damaged, or chemically treated hair.

Formulated with keratin, biotin, collagen, and castor oil, this 3.4 fl oz deep conditioner is built to rebuild weakened hair fibers while adding slip and shine. It works on all hair textures—straight, wavy, curly—and targets the common effects of heat styling, coloring, and environmental stress without weighing hair down. The mask combines protein rebuilding with moisturizing agents so hair feels reinforced yet flexible.

How does this mask rebuild and protect damaged strands?

The formula supplies keratin protein to fill gaps along the hair shaft, helping restore structural integrity. Collagen and biotin support elasticity and surface resilience while castor oil seals moisture for a smoother cuticle. Regular use can improve manageability and reduce breakage from daily styling.

• Keratin proteins help temporarily reconnect split or weakened areas.
• Collagen enhances surface strength and improves texture.
• Biotin supports overall strand resilience and appearance.
• Castor oil locks in moisture to reduce friction and breakage.

When should I use this deep conditioner in my routine?

Use the mask 1–2 times weekly or as needed for intensive repair after chemical services or heat styling. Apply after shampooing on towel-dried hair, leave on for 5–15 minutes depending on damage level, then rinse thoroughly. For a light maintenance boost, leave on shorter; for deeper repair, use a longer leave time or cover with heat.

• Post-shampoo treatment for best absorption.
• Shorter applications for fine hair; longer for severely damaged hair.
• Can be used before a styling session to smooth and detangle.
• Safe for colored and chemically treated hair when used as directed.

Will this mask weigh down fine hair or make curls stiff?

The concentrated protein is balanced with lightweight moisturizing agents so it strengthens without creating a heavy buildup when used correctly. Fine hair benefits from shorter applications and smaller amounts, while thicker or coarser textures can use more product for full coverage. Curls remain defined due to added hydration and improved cuticle alignment rather than stiffness.

• Use a pea-sized amount for short or fine hair.
• Apply generously on mid-lengths to ends for thick, coarse hair.
• Rinse well to avoid residue and maintain natural movement.
• Combine with leave-in products for added definition if desired.

How does this product help with frizz and shine?

Keratin smooths the hair surface while castor oil and collagen add gloss and lock in moisture, creating a sleeker appearance. By filling gaps and aligning the cuticle, the mask reduces the tendency of hair to absorb humidity and frizz. The result is shinier, more controllable hair that reflects light better.

• Cuticle-smoothing keratin reduces surface roughness.
• Moisturizing castor oil helps seal hydration and calm flyaways.
• Collagen boosts overall sheen and healthy-looking hair finish.
• Leaves hair easier to style and less prone to humidity-induced frizz.

Who is this for: VITAMINS hair cosmetics Keratin Hair Mask is suitable for anyone wanting to repair and hydrate stressed hair—people who color or chemically treat their hair, heat-style regularly, or live in dry or humid climates. It suits all textures from fine to coily when used in tailored amounts: lighter applications for delicate hair and richer treatments for thick, damaged lengths. If you want a salon-style protein and moisture treatment at home that targets strength, manageability, and shine, this mask is a practical addition to your weekly hair care routine.
