How to Strengthen, Repair & Hydrate Dry, Damaged Hair

 That’s where our Haircare Collection comes in. Built on nearly 30 years of skincare science (yes, skin and hair have very similar natural building blocks), this revolutionary new system visibly strengthens, repairs and hydrates every strand. It’s comprehensive hair repair that works beyond the cuticle (the outermost layer of hair). 

Before we dive into how it works, though, it’s important to understand how your hair got here in the first place. 

Why Hair Gets Dry & Damaged & How to Repair It 

There are a variety of reasons hair can become dry, brittle and damaged. Some of the top causes include using hot tools too often and/or without a heat protectant, frequent colouring or bleaching, over washing, environmental exposure and even age. Signs include noticeable breakage, split ends, coarse texture, loss of shine, loss of volume, excess shedding, and thinning. The list goes on. 

The common misconception to counter such “symptoms” is to pile on the hydration, but that alone is not enough. A multi-level approach is key to adequately address each strand. This means supporting your hair’s structure, protecting it from future damage with antioxidants and environmental shields and sealing in the moisture. 

To do all the above, each of our innovative hair formulas: 

1. Strengthens. A next-generation keratin complex, featuring three forms of keratin, visibly fortifies hair strands, reduces breakage and protects against colour loss. 
2. Repairs. An amino acid-rich encapsulated bio-tech matrix remains on hair for 24 hours to help visibly restore fragile, damaged hair and improve the look of thickness, volume and elasticity. 
3. Hydrates. Ultra-nourishing ingredients, including hyaluronic acid, deliver instant and long-lasting hydration, leaving hair looking and feeling ultra soft, silky and glossy.

The Power of Amino Acids in Hair Repair 

Amino acids are essential for maintaining strong, healthy hair. In our formulas, they come from wheat and soy proteins that provide a blend of key amino acids, including arginine, cysteine, and proline, to help repair and strengthen dry, damaged strands. These naturally derived amino acids closely match the composition of your hair’s own keratin, helping to restore softness, shine and resilience. 

Key Functions: 

• Strengthen and rebuild the hair’s structure with amino acid cysteine, which supports keratin bonds for smoother, more flexible strands 
• Improve softness and elasticity with amino acid proline, which helps hair feel smooth and manageable 
• Nourish the scalp and support fuller-looking hair with amino acid arginine, which delivers essential nutrients to the root 
• Support the amino acids that build keratin, helping reduce breakage and improve resilience 
• Maintain the amino acid profile of healthy hair, enhancing shine, hydration and smoothness 

By replenishing the amino acids in hair structure with wheat and soy amino acids, each strand becomes stronger, softer and visibly healthier over time. 

The Complete Science-Backed Haircare Routine for Dry, Damaged Hair 

STEP 1: CLEANSE 

Start each wash day with our intensive Triple Keratin Repair Shampoo that nourishes and replenishes dry, damaged hair. Infused with the ingredients noted above and our hyaluronic vitamin blend, it transforms brittle strands into soft, glossy, healthy-looking hair that appears fuller and more resilient.

STEP 2: CONDITION 

Post-shampoo, lock in all that hydration with our Hydrating & Strengthening Conditioner, powered by keratin, amino acids, multi-molecular weights of hyaluronic acid and pro-vitamin B5. Its restorative formula leaves hair looking stronger, smoother and silkier with a healthy, glossy shine. 

STEP 3: PROTECT 

Spritz our weightless Hydrating & Strengthening Daily Leave-in Spray through your hair after every wash to improve manageability and helps maintain hair colour vibrancy. The result is enviably smoother, silkier, shinier hair. 

EXTRA: MASK 

Use our Hydrating & Strengthening Moisture Hair Mask once or twice a week in place of conditioner to renew weakened, fragile strands with essential hydration while preventing breakage. Its ultra-rich, luxurious texture helps visibly strengthen damaged hair to improve the look of hair smoothness, bounce and shine.
