Hair care after keratin treatment is what actually decides how long your results last — not the treatment itself. The wrong shampoo can undo weeks of smoothness in a matter of washes.
Hair care after keratin treatment matters more than most people expect going in — the products you reach for in the shower afterward decide how long your results actually hold. Ordinary shampoo is built to strip oil and buildup, and it does that job well enough to strip out the very treatment you paid for, too. This guide covers the FELPS Omega Zero Açaí Oil aftercare range at Timeless BD: what each product actually does, how often to use it, and how to build a routine that protects your results instead of quietly washing them away.
Hair Care After Keratin Treatment: Why Regular Shampoo Works Against It
Most everyday shampoos rely on strong detergents — sulfates being the most common — to cut through oil fast. That's exactly what you don't want after a keratin, nanoplastia, or color service: those same detergents strip the treatment out of the hair shaft faster than normal wear would. Frequent washing, hot water, and swimming in chlorinated water all work the same way, wearing down results well before they'd naturally fade on their own.
The practical fix isn't complicated — it's switching to a gentler, treatment-specific shampoo and conditioner, washing a little less often, and using a deep-conditioning mask on a regular schedule rather than only when hair already feels rough.
The FELPS Omega Zero Açaí Oil Aftercare Range
FELPS Professional, the Brazilian brand behind Omega Zero, positions this range specifically as an after-chemical routine — meant to follow a keratin or nanoplastia service (or simply protect color-treated hair) rather than replace it. The açaí oil in the formula is the same ingredient FELPS uses across its treatment line, so the aftercare products are built to work with, not against, whatever service came before.

Omega Zero Açaí Oil Shampoo — the everyday cleanser
A gentler, sulfate-conscious shampoo meant to be your default wash between treatments. It cleanses without the aggressive stripping action of a regular drugstore shampoo, which is the main reason a smoothing treatment or color service fades faster than it should.
Omega Zero Açaí Oil Conditioner — every wash, non-negotiable
Pair this with the shampoo every time you wash. Skipping conditioner after a treatment is one of the fastest ways to see results fade early — it's not an optional extra step here, it's part of the same routine.
S.O.S Mask — the weekly deep-repair step
A heavier, once-a-week treatment for hair that's noticeably dry, damaged, or coming off a chemical service. This isn't a daily conditioner replacement — it's the step that catches damage before it becomes breakage. The 300ml size suits a single user's ongoing routine; the 1000ml is better value if you're maintaining several heads of treated hair or simply go through product quickly.
A simple rule of thumb: shampoo and condition every wash, mask once a week. If your hair still feels rough or dry between masks, that's a sign to wash less often — every two to three days rather than daily — rather than reaching for a stronger product.
Where Clarifying Shampoo Fits In
FELPS Clarifying Shampoo does a different job to the everyday Omega Zero shampoo, and it earns its own place in the routine rather than being an everyday swap-in. Use it in two situations: always right before your next chemical service, so the treatment processes evenly on clean, buildup-free hair — and, in between services, as a periodic deep-clean every three to four weeks to clear the product buildup, hard-water minerals, and styling residue that an everyday shampoo leaves behind. Used that way, it actually extends how fresh your results look rather than working against them; it's a stronger formula, which is exactly why it's a periodic step rather than a daily one.
Building a Weekly Routine
Here's the full hair care after keratin treatment routine broken into a simple weekly rhythm:
- Wash days (2–3x a week): Omega Zero Açaí Oil Shampoo, followed by the Conditioner every time.
- Once a week: swap the conditioner for S.O.S Mask on one of your wash days.
- Every 3–4 weeks, and always before your next service: one deep-clean wash with FELPS Clarifying Shampoo to clear buildup.
- Ongoing: keep hot water to a minimum and avoid chlorinated pools where possible — both work against the same results you're trying to protect.
Frequently Asked Questions
How often should I wash treated hair?
Every two to three days rather than daily is the general guidance for anyone maintaining a keratin, nanoplastia, or color treatment. Washing less often reduces how much the treatment is exposed to detergent and hot water, both of which shorten how long results last.
Can I use a regular shampoo instead of Omega Zero?
You can, but most regular shampoos contain stronger detergents that strip smoothing and color treatments faster. If you've invested in a treatment, a gentler, treatment-specific shampoo is the more cost-effective choice over the life of the result.
Is the S.O.S Mask a replacement for conditioner?
No — use conditioner every wash and the mask roughly once a week as an added deep-repair step, not as a swap for your everyday conditioner.
When should I use Clarifying Shampoo?
Right before your next chemical service, and as a periodic deep-clean every three to four weeks in between, to clear buildup that an everyday shampoo leaves behind. It's a stronger formula than your daily shampoo, which is why it's a periodic step rather than a daily one — not because it should sit unused on the shelf.
What's the best hair care after keratin treatment routine, in short?
Sulfate-conscious shampoo and conditioner every wash, a deep-repair mask once a week, a clarifying deep-clean every three to four weeks, and washing every two to three days rather than daily. That combination is what actually protects the investment you made in the treatment itself.
