Product Overview

Give your fine to medium hair the intensive care it deserves with the OUAI Fine to Medium Hair Treatment Masque. This luxurious mask is expertly formulated to repair, hydrate, and restore shine without weighing hair down. Enriched with shea butter, keratin, and panthenol, it penetrates deep into the hair shaft to strengthen from within while locking in moisture. Free from parabens, phthalates, and sulfates, this gentle yet powerful masque is suitable for all hair types, especially fine to medium textures that need a moisture boost without heaviness.

Key Features and Benefits

  • Deep Repair & Strengthening: Keratin, a key structural protein, helps rebuild damaged hair fibers, reducing breakage and split ends. Panthenol (pro-vitamin B5) penetrates the hair cortex to improve elasticity and resilience.
  • Intense Hydration: Shea butter is rich in fatty acids and vitamins, providing deep moisture that softens and smooths the hair cuticle. This helps combat dryness and frizz while enhancing natural shine.
  • Lightweight Formula: Specifically designed for fine to medium hair, this mask delivers rich nourishment without leaving residue or causing limpness. Hair feels bouncy, voluminous, and full of life.
  • Clean Beauty: OUAI is committed to clean ingredients. This masque is paraben-free, phthalate-free, and sulfate-free, making it safe for color-treated and chemically processed hair.
  • Salon-Quality Results: Enjoy professional-grade hair care at home. The mask improves manageability, reduces tangles, and leaves hair silky smooth with a luminous glow.

How to Use

For best results, use the OUAI Treatment Masque once or twice a week in place of your regular conditioner. Start with clean, damp hair. Apply a generous amount from mid-lengths to ends, focusing on the driest areas. Gently detangle with a wide-tooth comb and leave on for 5–10 minutes. Rinse thoroughly with cool water to seal the cuticle and maximize shine. For an extra boost, use a shower cap and allow the mask to penetrate for 15–20 minutes.

Who It Is For

This masque is ideal for anyone with fine to medium hair seeking repair, hydration, and shine. It is particularly beneficial for:

  • Dry or dehydrated hair due to heat styling, coloring, or environmental factors.
  • Damaged hair from over-processing or chemical treatments.
  • Color-treated hair needing gentle, sulfate-free care.
  • Curly or wavy hair that requires moisture without weight.
  • Low porosity hair that struggles to absorb heavy products.
