OUAI Fine to Medium Hair Treatment Mask, 8 oz — Lightweight Deep-Conditioning & Strengthening

This salon-quality treatment mask from OUAI replenishes moisture and improves manageability for hair that needs repair but can’t handle heavy formulas. Formulated with shea butter, panthenol, and hydrolyzed keratin, it targets frizz, split ends, and dullness while staying free from parabens, phthalates, SLS, and SLES. The cruelty-free, gluten-free blend rinses clean and enhances shine so hair looks healthier after each use.

How will this mask improve fine or medium hair without making it greasy?

The mask uses a lightweight conditioning base that delivers hydration where it’s needed most—mid-lengths to ends—so strands gain softness without added weight at the roots. Ingredients like panthenol and hydrolyzed keratin fortify and smooth the hair shaft, while shea butter provides emollience without heavy buildup.

• Light formula designed for fine-to-medium textures
• Targets mid-lengths and ends, not roots
• Panthenol for moisture retention and bounce
• Hydrolyzed keratin to strengthen and reduce breakage

What results can I expect after using OUAI treatment mask?

After use, hair should feel softer, appear shinier, and be easier to detangle and style. Over multiple treatments, you may notice fewer flyaways and improved manageability as the conditioning agents help seal the cuticle for smoother texture.

• Instant softness and improved slip for combing
• Enhanced shine without greasy residue
• Progressive smoothing with repeated use
• Reduces the appearance of damage and frizz

How do I use the mask for best results in my routine?

Use after shampooing: apply a generous amount from mid-length to ends, comb through to distribute evenly, leave on for the recommended time, then rinse. Finish with cool water to help seal the hair cuticle and lock in gloss; pair with your preferred OUAI shampoo for a cohesive regimen.

• Apply after cleansing, focus on mid-lengths to ends
• Comb through for even coverage and detangling
• Rinse with cool water to help seal and add shine
• Use weekly or as needed for deeper repair
