Repair Damage & Reconstruct Strands

This dynamic duo of shampoo and conditioner is formulated with scientifically proven and natural ingredients which target damage by reconstructing and hydrating the hair strands from inside out. Preventing breakage, sealing split ends, and rejuvenating your hair while eliminating frizz and increasing plumpness.

No Added: Silicones, Parabens, Sulfates or Sodium Chloride

Women with damaged hair. This can be a result of heat styling, color treatments, chemical treatments, sun exposure, pollutants or humidity.


Signs of damaged hair include:

  • Excessive tangling

  • Lack of elasticity

  • Split ends and frizz

  • Breakage

  • Thin ends

  • Dryness


Our formula is charged with two types of fast-absorbing proteins: Hydrolyzed Collagen and Hydrolyzed Keratin. 


Both are essential to increasing hair elasticity and reconstructing broken bonds. It also contains a blend of antioxidants which prevent damage from external factors.

  • Replenishes collagen topically

  • Repairs damaged hair

  • Rebuilds strand's internal structure

  • Boosts hair elasticity, preventing breakage

  • Eliminates split ends and frizz

  • Rejuvenates

How Does it Work?

Kerotin Collagen Line

The main damage repair actives are:


Hydrolized Collagen

  • Creates a protective layer around the hair cuticle, neutralizing free radicals and providing hair-building amino acids which reconstruct the hair fiber and increase hair porosity


Hydrolyzed Keratin

  • Penetrates the hair shaft and supplements it with broken-dow protein. This minimizes the damaging effects of heat styling, UV exposure, environmental pollutants and chemical treatments


The Result: Repaired, reconstructed and revitalized hair with minimal breakage and frizz

How To Use

Lather a coin-size amount onto wet hair and massage thoroughly. Let it sit for 30 seconds to 1 minute for the scalp and hair follicles to properly absorb the nutrients. Rinse with lukewarm water and repeat if needed.


After shampooing, apply the Collagen Conditioner. Lather a coin-size amount through wet hair starting from the hair tips and upwards (avoid roots if you have an oily scalp). Leave the conditioner for 1 to 2 minutes. Rinse your hair thoroughly and enjoy your clean hair.


For deep conditioning, use the Collagen Mask once a week instead of the conditioner, or if you have very dry and coarse hair, use the mask and the follow with the conditioner after rinsing.

Why is Collagen Important?


Collagen levels start decreasing in our mid-twenties by 1.5% yearly and up to 30% in the first five years of menopause.


Collagen is a structural protein that helps maintain hair elasticity and structure. A lack of it can lead to breakage and loss in the vibrancy of skin and hair, causing poor follicle function and anchorage from the scalp.

FAQs

How frequently should the line be used?

You can use this everyday as it is silicone free and will not weigh down hair with use. The formula will continue to repair and rejuvenate hair structure with each use.

Does the shampoo lather up?

No, our products are sulfate free and for that reason our products do not offer the sudsy, lather experience. However, the lack of sulfates does not compromise the quality of the cleanse obtained by the hair and scalp and instead, prevents damage.

Is it Curly Girl Approved?


Yes, the shampoo is CGM approved, It can be used during wash day to repair hair structure and enforce hair texture with prolonged use. However, the conditioner and mask are not CGM approved. 

How does it smell like?

The formula is lightly citric with notes of lavender

Does this line help with growth and thickening?

The line helps with damage repair by restoring the hair’s natural integrity and increasing elasticity which in turn, prevents early breakage and allows hair strands to fully develop. By helping with the overall health of your hair and scalp, the line helps with hair growth, but to specifically stimulate growth and thickness, we would recommend our Freshening Line.

Smells amazing

This is great since it is safe for colored hair. It smells amazing. It actually lathered up very nicely. It detangled my hair, dramatically reduced my frizz but still gave me lots of body. Which I have fine, wavy, extremely frizzy and tangly hair. Lately my hair is flat. This helped a lot! The hair photo has no products in is from using everything the night before. Usually my hair is a frizzy mess in the morning.

Best line ever.

I had such a good experience using these products. They were easy to use, beautiful packaging and gave tips on what other products they work best with. My favourite part was the collagen mask which as soon as I applied I was shocked at how much softer my hair felt. After two uses my hair genuinely seemed healthier.

Fuller, healthier

I purchased the hair growth vitamins and the thickening spray, the oil, and a sample of shampoo and conditioner. I’m going to be a customer for life. I’m 68 yrs old with long hair and have had more people mention how great my hair looks since I started using Kerotin products. I also purchased the scalp massager which I absolutely love!
