VITAMINS hair cosmetics Keratin Hair Mask 3.4 fl oz — Deep Protein Repair with Biotin & Castor Oil for Dry, Damaged & Frizzy Hair

This concentrated 3.4 fl oz treatment combines keratin protein with biotin, collagen and castor oil to target broken, brittle areas and restore elasticity and shine. It is formulated as an intensive deep conditioner to be used weekly or as-needed to refresh texture, reduce surface frizz and improve comb-through ease without weighing hair down. The formula works on a variety of hair types—curly, straight, color-treated or heat-styled—providing salon-style conditioning at home.

How does this keratin mask repair damaged hair?

The mask delivers keratin proteins that help fill weakened spots along the hair shaft, while collagen supports surface strength and body. Together with emollients and oils, it rebuilds feel and reduces roughness for smoother cuticles.

• Keratin proteins penetrate to reinforce stressed strands
• Collagen adds tensile support and fuller-looking fiber
• Castor oil and conditioning agents seal moisture and tame flyaways

Will it work for both curly and straight textures?

Yes—its concentrated conditioning base adapts to different textures by restoring moisture and defining pattern without flattening natural volume. Curly hair gains improved curl definition and less frizz, while straight hair finds a silkier, shinier finish.

• Lightweight enough to avoid limpness on fine hair
• Intense hydration for coarser, drier curls
• Improves manageability for detangling and styling

How do I use the VITAMINS Keratin Hair Mask for best results?

Apply to clean, towel-dried hair focusing on mid-lengths to ends; leave on according to hair condition, then rinse thoroughly. Use weekly or more often on very dry or chemically treated hair for a restorative regimen that complements your shampoo and styling routine.

• Shampoo and towel dry before application
• Work evenly through lengths, avoiding the roots for finer scalps
• Leave 5–20 minutes depending on damage level, then rinse

What benefits do biotin and castor oil bring to this treatment?

Biotin supports overall hair resiliency and surface health, while castor oil delivers concentrated hydration and helps smooth the cuticle. Together they enhance the mask’s conditioning effect and improve the look of fullness and sheen.

• Biotin helps maintain stronger-feeling strands
• Castor oil locks in moisture and reduces dryness
• Combined with keratin and collagen for comprehensive conditioning

Who is this for: This VITAMINS keratin mask is designed for anyone seeking intense repair and smoother texture—ideal for people with chemically processed, heat-damaged, dry or frizz-prone hair, as well as those who want a restorative weekly deep conditioner to boost manageability and shine.
