OUAI Fine-to-Medium Hair Treatment Mask — Lightweight Deep-Conditioning, 8 oz with Shea Butter & Keratin

OUAI Fine to Medium Hair Treatment Mask is a lightweight deep-conditioning treatment that hydrates, smooths, and strengthens fine-to-medium hair without weighing it down.

This salon-grade mask is formulated for strands that need repair and moisture without heaviness. OUAI combines shea butter, panthenol, and hydrolyzed keratin to deliver slip, elasticity, and shine while keeping hair airy and touchable. The formula avoids parabens, phthalates, SLS and SLES and is cruelty-free, so it fits well into cleaner, modern routines where performance matters.

How will this mask improve my hair’s texture and manageability?

The mask replenishes moisture and smooths the hair cuticle to reduce tangles and frizz for easier styling. Lightweight emollients hydrate without leaving a greasy residue, while panthenol helps with softness and manageability.

• Shea butter provides controlled moisture and natural shine.
• Panthenol adds slip for easier comb-through and fewer breakages.
• Hydrolyzed keratin helps rebuild strength and reduce porosity.

Can I use this on color-treated or damaged hair?

Yes — the mask is safe for color-treated strands and supports recovery of weakened hair. Its reparative actives work to fortify fibers and lock in hydration without stripping color or adding weight.

• Strengthens hair bonds with hydrolyzed keratin.
• Restores soft feel after chemical or heat exposure.
• Formulated without harsh sulfates or parabens to protect color integrity.

How should I apply it to get the best results?

After shampooing, comb a generous amount through mid-lengths to ends and leave on for 3–5 minutes, or longer for more intense repair. Rinse with cool water to help smooth the cuticle and lock in shine.

• Use once or twice weekly for maintenance; more often if hair is very damaged.
• Pair with an OUAI shampoo for a matched routine.
• Apply to towel-dried hair for optimal absorption and even coverage.

Will this product weigh my hair down or make it look flat?

No — it’s specifically balanced for fine-to-medium textures so hair stays light and voluminous after treatment. The conditioning agents provide moisture and smoothing action without heavy oils that can dull movement.

• Formulated to avoid residue and excess oiliness.
• Delivers shine and softness while preserving body and bounce.
• Easy-rinse formula prevents buildup with regular use.

Who this is for: Ideal for anyone with fine to medium hair seeking a targeted deep conditioning treatment that repairs and hydrates without flattening the hair. If you routinely color, heat-styling, or use chemical services and want a clean, cruelty-free mask that improves manageability and strength, this OUAI treatment is tailored to those needs. Use it as a weekly restorative step or as-needed rescue to refresh texture, reduce frizz, and support healthier-looking strands.
