Boticário Match Lab Multi-Benefit Rebuilding Leave-In – Reduces Porosity, Repairs Cuticles & 230°C Heat Protection – 5.07 fl oz (150 ml)

Boticário Match Lab Multi-Benefit Rebuilding Leave-In (150 ml / 5.07 fl oz) is a rinse-free finishing and rebuilding leave-in created for every hair type that has been through a lot — damaged, bleached, color-treated or chemically processed strands that feel rough, porous and hard to manage.

Made in Brazil by O Boticário, one of the country’s most loved beauty houses, this leave-in belongs to the Match. Lab line, the brand’s laboratory-driven answer to fibre reconstruction. Brazilian hair care is famous worldwide for turning heavily processed hair into soft, aligned, touchable strands, and this formula is a compact example of that expertise.

The vegan, lightweight cream layers a protective film over the cuticle, helps reduce the appearance of porosity and supports the hair fibre against the heat of your blow-dryer, with thermal protection up to 230 °C (446 °F). Use it on damp hair before styling or on dry hair as a finisher.

Key Features:

• Reduces porosity: helps smooth and reseal a raised cuticle so hair looks less rough and holds moisture better.
• Rebuilds with proteins: a blend of wheat, corn and soy proteins plus free amino acids helps repair the look and feel of the hair structure.
• Thermal protection up to 230 °C (446 °F): a heat-shield layer for blow-drying and hot-tool styling.
• Helps prevent chemical damage: supports strands that go through bleaching, coloring or straightening routines.
• Restores cuticle integrity: Lactic Acid helps balance the pH of the fibre and fights the visible signs of dryness.
• Antioxidant action: Tocopheryl Acetate (vitamin E) supports the fibre against day-to-day oxidative stress.
• Vegan, rinse-free and travel-friendly: 150 ml of concentrated cream that works on all hair types, no rinsing required.

How To Use

1. Dispense a small amount of leave-in into your palm — start with less than you think you need.
2. Apply along the lengths of the hair, avoiding the roots.
3. On damp hair: distribute evenly before blow-drying to help protect the strands from the heat of the dryer.
4. On dry hair: work a tiny amount through the mid-lengths and ends for a finishing, anti-frizz effect.
5. Do not rinse. Style as usual.

Expert Tip: emulsify the cream between your palms first, then press it into the most damaged sections (usually the ends and the face-framing pieces) before spreading whatever is left over the rest of the hair — this keeps fine hair from going flat while still protecting the areas that need it most.

Ingredients (Highlights)

• Lactic Acid: an alpha-hydroxy acid that helps regulate the pH of the hair fibre and helps reduce the appearance of dryness and roughness.
• Hydrolyzed Wheat, Corn & Soy Proteins + Triticum Vulgare (Wheat) Protein: small protein fragments that help fill in and repair the look of a weakened hair structure.
• Amino Acid Complex (Arginine, Glycine, Serine, Proline, Threonine, Valine, Alanine, Aspartic Acid): building blocks that support the resilience and softness of processed hair.
• Panthenol (Pro-Vitamin B5): a classic humectant that helps hair hold moisture and look more flexible.
• Tocopheryl Acetate (Vitamin E): provides the formula’s antioxidant action.
• Hydrolyzed Ceratonia Siliqua (Carob) Seed Extract: a plant-derived conditioning agent that helps leave strands soft and aligned.

FAQ

Is this a rinse-out treatment or a true leave-in?

It is a true leave-in. You apply it and leave it in the hair — no rinsing at any point.

Will it weigh down fine or low-density hair?

Not if you use a small amount. Start with a pea-sized quantity on the ends and lengths only, keeping it well away from the roots, and build up only if needed.

Can I use it every day?

Yes. It is designed for daily use on damp or dry hair, and it is especially useful on the days you blow-dry or use hot tools.

Is it safe for bleached, colored or keratin-treated hair?

Yes — it was developed exactly for that kind of hair. It supports strands that have been bleached, dyed or chemically processed, and it does not strip color.

Is the formula vegan, and does it contain any allergens I should know about?

The formula is vegan and cruelty-free. It does contain wheat, soy and corn proteins, so skip it if you are sensitive or allergic to wheat, gluten, soy or corn derivatives. As with any new product, patch test first.
