K18 Triple Bright Shampoo

Keep Blonde Bright While K18 Keeps It Strong

K18 Triple Bright Shampoo is for blonde, highlighted, or lightened hair that needs both toning and repair in the same step. It neutralizes brassiness and keeps blonde tones cool and vibrant while the K18PEPTIDE in the formula works to repair the damage that lightening causes. Because blonde and bleached hair takes the most chemical damage of any hair type, having a shampoo that addresses both the color and the structure at the same time makes every wash day count.

Best For

• Blonde, highlighted, balayage, or silver hair
• Lightened hair that is also damaged or brittle
• Anyone wanting purple or blue toning shampoo with real bond repair
• Platinum and very light blonde hair prone to brassiness

What It Helps With

K18 Triple Bright deposits cool, violet toning pigment to neutralize brassy yellow or orange tones in lightened hair while cleaning thoroughly. The K18PEPTIDE in the formula works simultaneously to repair broken bonds in the hair shaft, addressing the structural damage that all lightening processes cause. The result is blonde hair that looks brighter and fresher and hair that actually feels healthier after washing.

Why Clients Love It

Clients who get highlights or bleach services regularly know that purple shampoos can sometimes leave hair feeling dry or coated. K18 Triple Bright feels different because the repair peptide is working during the same wash. Clients say their hair feels softer and stronger with regular use than it did with other toning shampoos, and the brightness it keeps in blonde tones is noticeable wash after wash.

How to Use

Wet hair thoroughly and lather a generous amount through from roots to ends. For more toning, leave lather on for two to three minutes before rinsing. For regular maintenance, rinse after a standard shampoo massage. Use once or twice a week to maintain tone, or as needed based on how warm your hair pulls.

Pro Tip From Our Stylists

Leave it on for three to five minutes if your hair is pulling very warm or brassy between salon visits. The longer contact time deposits more toning pigment and gives a noticeably cooler, brighter result. Rinse thoroughly and follow with K18 Leave-In Mask on treatment days.

Frequently Asked Questions

Will it turn my hair purple?
No. The violet pigment is toning, not coloring. It cancels out brassiness by depositing cool tones that neutralize the warm ones. Leaving it on for an extended time may give a temporary slight purple tint on very light hair, which washes out with the next shampoo.

How often should I use it?
Once or twice a week is typical. If you alternate it with a regular shampoo, you get toning maintenance without over-depositing pigment.

Can I use it with the K18 Leave-In Mask?
Yes. Use K18 Triple Bright to shampoo, then apply the K18 Leave-In Mask immediately after without conditioning first. Do not use it on weeks when you use K18 PEPTIDE PREP Detox Shampoo, as the detox is for pre-treatment clarifying only.

Is it safe for all blonde hair?
Yes. It works on natural blonde, highlighted, balayage, platinum, and silver hair.

Does the repair benefit work even if I leave it on for only a minute?
The K18PEPTIDE works on contact, so any amount of exposure provides some benefit. More contact time gives more toning; repair happens regardless of timing.
