OUAI Fine to Medium Hair Treatment Masque – 3.4 oz lightweight repair mask with shea butter & keratin for hydration and shine

OUAI Fine to Medium Hair Treatment Masque is a lightweight deep-conditioning mask that restores hydration, reduces frizz, and strengthens fine to medium strands without weighing hair down.

This intensive treatment was formulated for fine and medium hair types that need moisture and repair but can’t handle heavy, greasy formulas. Infused with shea butter, panthenol, and hydrolyzed keratin, the masque targets dryness, split ends, and brittleness while leaving hair soft, manageable, and glossy. The scent, Melrose Place, blends rose with bright bergamot, lychee, white musk and champagne notes for a subtle, luxe finish.

How will this masque improve my damp hair routine?

Use this masque after shampooing on towel-dried hair to deliver concentrated moisture where it’s needed most. A short five-minute treatment timeframe makes it easy to add into busy mornings or relaxed evenings without a lengthy sit time. Rinsing with cool water helps seal the hair cuticle and enhance shine.

• Apply a quarter-size amount from ends to mid-lengths, avoiding excess at the roots.
• Leave on for about 5 minutes; suitable for weekly or as-needed deep care.
• Rinse with cool water to lock in hydration and boost shine.

What ingredients deliver the repair and shine?

The formula combines emollients and strengthening agents to both smooth and fortify each strand. Shea butter provides lightweight moisture and softness, panthenol (pro-vitamin B5) improves elasticity and shine, and hydrolyzed keratin helps rebuild weakened hair fibers. The result is improved texture and reduced frizz without a heavy finish.

• Shea butter — hydrates and conditions dry or processed hair.
• Panthenol — enhances shine and strengthens elasticity.
• Hydrolyzed keratin — repairs and reduces breakage for smoother strands.

Will this product weigh down fine hair or affect styling?

No — the masque is balanced for fine to medium hair so it restores moisture without leaving residue that flattens styles. Because the texture is lighter than traditional heavy masks, it improves manageability and helps hair hold shape after styling. It’s also free from parabens, phthalates, sulfates and other common heavy additives.

• Light-to-medium consistency designed for thinner strands.
• Formulated without parabens, phthalates, SLS/SLES, and gluten.
• Rinse thoroughly to maintain natural volume and movement.

How does OUAI fit into a sustainable and cruelty-free routine?

OUAI products are cruelty-free and made without several common harsh ingredients, making them a practical choice for conscious shoppers. The packaging for this masque is recyclable, and the brand emphasizes ingredient transparency and formulas that perform. Using this masque in place of heavier daily conditioners can reduce overall product use while delivering targeted care.

• Cruelty-free formulation — no animal testing.
• Recyclable packaging — designed to be reused in local recycling streams.
• Concentrated treatment reduces frequency of heavier styling products.

Who is this for: This treatment masque is ideal for people with fine to medium hair who want visible repair, extra moisture, and reduced frizz without sacrificing volume. It suits chemically treated, heat-styled, or naturally dry hair that needs targeted strengthening and shine. If you need a fast, effective deep conditioner that won’t weigh hair down and prefers cleaner, cruelty-free formulas, this product fits the bill.
