Why Hair Turns Brassy After Keratin — and How to Fix It Without Damage
Expert tips for blondes and light tones using Brasil Cacau Keratin
First: Yes, Brassiness Happens — Here’s Why
After a keratin treatment, it’s common for blonde or light-colored hair to take on a warmer or even yellow-orange tint. This is due to a temporary shift in pH and heat exposure during the treatment process, which may subtly lift underlying warm pigments — especially in pre-lightened or bleached hair.
If this happened to you after using the Brasil Cacau Reconstruction Kit, don’t panic. The fix is simple, safe, and stylist-approved.
Use a Purple Toning Shampoo — Carefully
The most effective way to neutralize unwanted yellow or brassy undertones is to use a professional purple shampoo.
Why it works:
– Purple pigments cancel out yellow tones (color theory 101)
– Keeps cool blonde, silver, or ash tones fresh and balanced
– Works without affecting the integrity of your keratin treatment
💡 Tip: Choose a sulfate-free, keratin-safe formula to preserve smoothness and shine.

When Can You Start Using It?
Unlike other treatments that require a long waiting period before toning, with Brasil Cacau you can begin toning once the initial 48-hour post-treatment window has passed.
Here’s the correct schedule:
– First 48 hours: Don’t wash or wet your hair at all
– After 48 hours: You may begin using purple shampoo
– Best practice: Use it once a week for maintenance
There’s no need to overdo it — once a week is enough to keep your tone bright and neutralized.

Can You Color Your Hair After Keratin?
Yes — but timing and technique are everything.
If you plan to color your hair after a keratin treatment:
– Always consult your stylist first
– Wait at least 7–10 days post-keratin for optimal results
– Avoid high-lift or bleach-based color immediately after treatment
With professional guidance, you can safely enhance or refresh your color without compromising the smoothing effects of Brasil Cacau.
Final Thoughts: Smooth, Shiny, and Cool-Toned — It’s Possible
The Brasil Cacau Reconstruction Kit delivers long-lasting frizz control and silky results — but blonde and light-haired clients need a smart aftercare routine to maintain tone.
With the right toning strategy, you don’t have to choose between smoothness and color clarity.
And if you ever have doubts, ask your stylist to create a custom aftercare plan — because perfect hair should never come with guesswork.
