Kostume Rio de Janeiro USA Nero Black Apparel Color-Depositing Mask
Dark hair doesn't fade to lighter — it fades to brassy. This Brazilian color-depositing mask lays cationic black pigment back onto the hair with every use, restoring the depth and glassy finish that dull, washed-out black and deep brunette loses over time.
Made in Brazil, where humidity, sun, and salt make hair repair a daily science rather than a seasonal fix. Lactic acid clears buildup and tightens the cuticle first, so pigment sits evenly and holds — that's what turns a color refresh into color retention.
[SENSORY LINE — one sentence on texture, scent, and pigment depth. Replace with what's true.]
What it does
- Refreshes and deepens black and dark brunette tones
- Deposits pigment with no developer and no damage
- Tightens the cuticle to improve color retention
- Balances the pH of hair and scalp for smoother, shinier hair
- Gently clears buildup and excess oil from the scalp
- Reduces static, frizz, and tangles for a glossy, polished finish
Key ingredients you'll love
- Cationic Black Pigments — deposit directly onto the hair to intensify dark tone
- Lactic Acid — exfoliates the scalp, balances pH, and tightens the cuticle
- Behentrimonium Chloride — conditioning agent that smooths the cuticle and cuts static
- Hydrolyzed Keratin — repairs the look of damage and restores smoothness
- Collagen — strengthens hair structure and improves elasticity
- Hyaluronic Acid — retains moisture and helps reduce fragility
Rounded out with sunflower, macadamia, olive, avocado, and cambre oils plus glycerin, forming a protective film that locks in moisture.
Best for
- Black and deep brunette hair, natural or colored
- Dark color-treated hair fading brassy or dull
- Stretching the time between salon appointments
- Adding depth and gloss to dark hair
- Anyone whose color mask leaves hair dry
How to use
- Shampoo and towel-dry. Wear gloves — pigment stains.
- Apply evenly through mid-lengths and ends, combing to distribute.
- Leave on 20 minutes.
- Rinse thoroughly and style as usual.
Pro tip: If your hair is very porous or lightened, do a strand test first — black pigment grabs hard and can go darker than you want.
