Boticário Match Science Pré e Pós-Química Hair Mask – Rebuilds the Cortex & Cuts Breakage by 54% – 8.81 oz (250 g)

Match. Science Pré e Pós-Química Hair Mask (250 g / 8.81 oz) is the reconstruction step of the Brazilian hair schedule ("cronograma capilar"), created by O Boticário for hair that has been through color, relaxing, bleaching or any other chemical service. It works deep in the cortex, helping to reconnect the internal bonds that chemistry leaves behind and helping hair recover its natural strength from the very first application.

The formula pairs Itaconic Acid with an Amino Acid Micro-Infusion that reintegrates and restructures the hair fiber while it repairs, hydrates and protects each strand. According to the brand's own testing, it delivers a 54% reduction in hair breakage, for stronger, silkier hair with an anti chemical-cut action.

Made in Brazil and shipped worldwide from MKPBR, this is a genuine Brazilian salon-inspired treatment straight from the country that turned hair care into a ritual.

Key Features:

• Rebuilds from the cortex: helps reconnect the hair bonds lost to chemical processing, restoring strength from the inside out.
• 54% less breakage (brand-reported): supports visibly stronger, more resilient strands from the first application.
• Itaconic Acid + Amino Acid Micro-Infusion: reintegrates and restructures the fiber while repairing, hydrating and protecting it.
• Anti chemical-cut action: helps reduce the appearance of mid-length snapping on colored, relaxed and bleached hair.
• Panthenol, flaxseed and chia extracts: add softness, suppleness and a silky finish without weighing hair down.
• Fast 3-minute ritual: a salon-style reconstruction step that fits into an everyday shower routine.
• Authentic Brazilian beauty: formulated and manufactured in Brazil by O Boticário, a certified cruelty-free brand.

How To Use

1. Wash your hair as usual and remove excess water so strands stay damp, not dripping.
2. Apply the mask along the lengths of the hair, concentrating on the most chemically processed areas.
3. Leave it on for 3 minutes.
4. Rinse thoroughly.

Expert Tip: use this mask as the reconstruction step of your hair schedule — alternate it with a hydration and a nutrition treatment across the week instead of using it every single wash, and comb it through with a wide-tooth comb so every strand is evenly coated.

FAQ

Is this mask suitable for hair that has been bleached or relaxed?

Yes. It was designed specifically for the before-and-after of chemical services, including color, bleaching, relaxing and permanent treatments, and it helps rebuild the fiber from the cortex.

How often should I use it?

Use it as the reconstruction step of your routine — most people use it once a week, or as needed when hair feels weak or brittle. Alternate with hydration and nutrition treatments for the best balance.

Can I use it if my hair is not chemically treated?

You can. If your hair is simply dry, fragile or damaged by heat styling, the amino acids and Panthenol still help strengthen and soften it — just space out the applications, since reconstruction is a treatment step rather than a daily conditioner.

Does it replace my conditioner?

On the days you use the mask, it can take the place of your conditioner. On other days, follow with the Match. Science Pré e Pós-Química conditioner or your usual one.

Is the packaging in Portuguese?

Yes — this is the authentic Brazilian retail product, so the label is printed in Portuguese. The full English usage steps and ingredient list are right here on this page.
