Olaplex Weightless Nourishing Mask - 200ml

Olaplex Weightless Nourishing Mask is a lightweight restorative mask for fine to medium hair, created to nourish without weighing hair down. Thanks to the signature bond-building technology, it reinforces the hair structure, improves elasticity, and reduces breakage. It hydrates, softens, smooths, and adds natural shine while maintaining lightness and volume. It works in 3–5 minutes, delivers results that last for up to 5 washes, and is suitable for color-treated, weakened, and damaged hair, leaving it smoother, more manageable, and full of life with regular use.

Technology

• Bond-building / Bis-Aminopropyl Diglycol Dimaleate — Olaplex’s signature bond-repair molecule that helps rebuild disulfide bonds in the hair (the core scientific concept behind Olaplex).
• Biomimetic Cuticle Technology — a technology designed to “seal” the cuticle, improving moisture retention and protection for multiple washes.
• Volume Boost Complex and Essential Hydra-Fresh Complex — developed to create airy volume and lock in moisture with minimal weight.

Formula and key ingredients

1. Bis-Aminopropyl Diglycol Dimaleate — the active Olaplex bond-repair agent that works on the level of disulfide bonds.
2. Moisture retention: Glycerin, Sodium Hyaluronate, Panthenol (Provitamin B5), Polyglutamic Acid — hydrate, increase elasticity, and boost shine.
3. Emollients/softeners: Hydrogenated Castor Oil/Sebacic Acid Copolymer, Shea Butter (Butyrospermum Parkii), Coconut Oil (Cocos Nucifera Oil), Capric/Caprylic Triglyceride — nourish and smooth the hair (in light, non–weighing-down concentrations for this product).
4. Cationic conditioning agents: Polyquaternium-37, Behentrimonium Chloride, Stearamidopropyl Dimethylamine — improve detangling and shine.
5. Antioxidants and botanical extracts: Rosa Canina (rosehip), Rosmarinus Officinalis (rosemary), Helianthus (sunflower), and others — provide additional support for cuticle health.

Texture

Texture: lightweight and serum-like, absorbs quickly and does not leave a heavy film — users often describe it as feeling more like a delicate hair lotion rather than a dense cream mask.

Who it is for / expected results

• Target hair type: fine to medium hair that needs moisture and strengthening without added weight. Suitable for color-treated and chemically processed hair, as well as hair damaged by heat styling.
• Expected results: softness, light volume and nourishment, reduced tangling and breakage, enhanced shine, plus a strengthening effect from bond technology with regular use. Actual results depend on the level of damage and on how it is combined with other Olaplex products.

Reviews and opinions

• Professional/media: recent reviews of new Olaplex launches (including the new mask line) note fast, visible shine and softness; many reviewers highlight that the masks work noticeably in just 3–5 minutes.
• Consumers: generally positive feedback from those with fine hair, who notice volume and no heaviness; however, some users with very dry/thick hair feel it does not give “enough” deep moisture, so they may prefer a richer, more nourishing mask.

How to use

Apply to freshly washed hair (after shampoo), distribute evenly through lengths and ends, leave on for 3–5 minutes, then rinse thoroughly. For more intensive care, it can be left on slightly longer, but the product is formulated as a quick mask for regular use. Frequency: typically once a week for fine to medium hair, and can be adjusted depending on the level of damage — frequent use of heavy oils and masks is usually not recommended for very fine hair. If hair is extremely fine, use a small amount and rinse very well to avoid build-up. If hair is thick and very dry/damaged, consider Rich Hydration Mask, which is recommended for coarser/drier hair types — Olaplex offers different masks tailored to hair type. For best results, pair with the professional Olaplex system (No.4 shampoo, No.5 conditioner, and other products), especially if there is chemical damage.
