Pigment loss happens, but that doesn’t mean rough texture, split ends, and frizz have to follow. Learn how molecular repair biotechnology supports and fortifies from the inside out to deliver healthy hair for all.


first, let’s back up a little—what causes grey hair, exactly?

DNA and age aren’t the only reasons hair goes gray. Cumulative environmental damage from things like pollution and UV rays stress the hair follicles, causing melanocyte cells (which make color-creating melanin) to die. 


Without melanin to fortify hair against damaging elements, hair begins to lose more pigment, and subsequently strength.

what does grey hair look + feel like?

As hair loses pigment, it becomes more prone to breakage. This is because the melanin that naturally protects it is no longer there. Without melanin, natural photoprotection is diminished, allowing ultraviolet radiation to cause damage to all layers of hair, weakening its strength and elasticity.


over time, this can make hair look + feel more:

  • thin 

  • brittle 

  • dull 

  • rough

Our patented K18PEPTIDE™ penetrates deep into hair’s innermost layers to repair broken polypeptide chains, working to fill in any gaps by reconnecting them immediately and over time. Hair accepts this biomimetic repair as natural, which allows it to more effectively strengthen, smooth, and renew on the deepest possible level.


Hair of every color—including grey—becomes stronger from the inside out, with lasting results that won’t wash away. 


how to add molecular repair to your routine

If you’re ready to add this breakthrough K18PEPTIDE™ to your routine, K18 Educator + PRO stylist Alifia has you covered

K18 MOLECULAR REPAIR MASK + K18 MOLECULAR REPAIR OIL BOTTLES

For her grey clients, Alifia recommends pairing the K18 molecular repair hair mask with K18 molecular repair hair oil. Use on damp hair for deep damage repair twice a month.


“Grey hair tends to get more brittle, which really inhibits growth and length retention—plus who wants crunchy hair?”

DAMAGE SHIELD SHAMPOO + CONDITIONER BOTTLES

The rest of the month Alifia says to lock in your molecular repair results, continue to protect hair from damaging environmental aggressors, and maintain hair strength with every wash.


“I recently started recommending DAMAGE SHIELD pH protective shampoo + DAMAGE SHIELD protective conditioner for between treatment days.”


She also tells her grey hair clients to try smoothing a few drops of the oil on dry hair throughout the week, “to keep the hair soft between shampoos.”
