Dry Hair Needs More Than a Surface Fix

The hair shaft is known as the cuticle. When heat, chemicals, and UV exposure takes assault, the outer layer becomes dehydrated and coarse — hair loses moisture, tangles easier, and starts to look dull and lifeless.

Most conditioners only coat the outer layer of the hair shaft. The Purifier Micellar Liquid Mask has a lightweight formula that absorbs deep into the hair due to its cationic properties. Its hydrating and restorative complexes leave hair in optimum condition with a smoother cuticle leaving hair tangle-free and shiny with visible results in five minutes.

WHAT IT DOES

Four Things That Happen in Five Minutes

The cationic properties allow the amino acids to penetrate deeper into the hair fiber within five minutes.

Moisture is absorbed rapidly by filling the porous sections of the hair creating smoothness, reducing frizz and static.

Due to its hydration and restorative benefits in conjunction with naturals oils these complexes helps to improve elasticity, shine and soothes the cuticle.

These complexes have been perfected in Rio by Kostume Rio de Janeiro to give lightweight results leaving hair with shine and volume.

The Activation Ritual

This isn't your ordinary heavy-weight mask you scoop from a tub. This formulation of complexes and advanced technology has put Purifier Micellar Liquid Mask in its own category. Due to its lightweight formula you're able to pump it directly into your palm. When applied into your hair in creates a creamy mousse texture.

Step 1 — Pre-cleanse (optional, but recommended for best results)
Shampoo with Purifying Anti-Metal Shampoo (use prior to any conditioning treatment.) Repeat twice for heavy build-up. This shampoo removes build-up from the cuticle of the hair shaft, allowing the Micellar Mask to absorb deeper into the hair fiber.

Step 2 — Application of Mask
Apply to very damp hair. Divide hair into four sections for optimal saturation. Dispense six (6) to eight (8) pumps into the palm of your hand or more depending on density of hair. Rub together to activate. You will feel a warm sensation due to its exothermic properties. (repeat for each section)

Step 3 — Distribute through hair
Work product through mid-shaft, ends, and up to the scalp. Comb throughly for best saturation. Pin hair up, shower, rinse thoroughly when finished.

Step 4 — Finish Towel dry and apply Purifying Spray Leave-In Conditioner. Apply liberally and style.

Seven Actives, Bottled in Rio

Deep Hydration Meets Restorative Strength
These actives create a moisture-rich restorative treatment for dry, weak, color-treated, and over-processed hair. Reconstructive Plex provides amino acids that work within the cortex to restore strength and elasticity. Macadamia and moringa oils, along with hydrolyzed quinoa and wheat proteins, replenish lost hydration. Cationic conditioning agents bind moisture and protein where hair needs it most — leaving hair deeply hydrated, resilient, and softer, with a shiny cuticle after every use.

Cationic agents are positively charged molecules drawn to the damaged, negatively charged areas of the hair — inside and out. They smooth the proteins and moisture in place so the hydration lasts well past rinse-out.

A plant-based protein rich in amino acids and moisture that helps protect and maintain color-treated hair, enhancing vibrancy and reducing fading.

This protein breaks down into moisture-binding peptides that attach to keratin, filling gaps within the hair's internal structure — while attracting moisture from the air and drawing it deep into the shaft.

A lightweight oil rich in essential fatty acids and vitamins — strengthens hair from the root, restores elasticity, and smoot the cuticle for hair that feels softer and detangles effortlessly.

Antioxidant-rich oil packed with vitamins and fatty acids that help to restore, hydrate, and smooth the cuticle on damaged hair.

An invigorating root extract rich in natural antioxidants that stimulates the scalp, helps soothe irritation, promotes healthier hair growth, and defends hair against environmental stress.

Cationic conditioning agents are positively charged molecules that are attracted to the negative areas of the internal and external parts of the hair shaft locking in proteins and moisture for overall health of the hair.

A restorative protein complex rich in amino acids — the building blocks hair is made of. It works deep within the hair shaft to rebuild the fiber from within, restoring resilience and elasticity so hair stretches instead of snapping. Less breakage, fewer split ends, and hair returned to its natural strength and shine.
