Can Peptide Bonds And Amino Acids Reverse Years Of Hair Damage? Let’s Investigate


I have naturally dry and frizzy hair that is often quite difficult to tame. On top of that, I’ve had my hair chemically coloured twice and smoothened. I also regularly use heat tools to style it and even though I use heat protection every time, I still fear the aftereffects. So it’s safe to say that I’m always looking for products to add to my routine that’ll make my hair look and feel healthy.

For those of us battling hair damage, the notion of a product range capable of reversing it within minutes seems nothing short of miraculous. Yet, the L’Oréal Professionnel Paris Absolut Repair Molecular range steps in as a beacon of hope for rejuvenating even the most distressed tresses.

What Causes Hair Damage?

Hair damage has evolved from external to internal levels¹–from split ends, colour fading and dullness to lack of elasticity, hair loss and high porosity. While external damage is easier to deal with, internal damage delves deep into the molecular structure. In fact, there’s so much information out there, thanks to social media and salon experts, that consumers are focusing more on reversing internal damage than repairing surface-level damage.

According to a study², a staggering 50% of 18-24-year-olds express concerns over hair damage, underscoring the need for an effective solution. In addition, damage is one of the top two hair concerns in India.

This is where the Absolut Repair Molecular range by L’Oréal Professionnel steps in. At its core lies a sophisticated fusion of amino acids and peptide bonders. These work together to repair compromised peptides and fortify the hair’s internal framework. In short, the products in this range work not only by providing the essential nutrients required for repair but also by going to its core to rebuild the molecular structure–thereby reversing up to two years of damage in a single application.³

Amino Acids

We’ve all heard of this ingredient but do we really know what it does? Well, amino acids are the building blocks of proteins. Their main benefits are strengthening the hair, fighting frizz and preventing breakage. They also stimulate growth by promoting blood circulation and collagen production.

In fact, the reigning buzzword, keratin, is made up of 18 types of amino acids. It gives your strands their structure, strength and elasticity⁴. But when the shafts are exposed to heat styling, chemical treatments, environmental factors or poor nutrition, their protein structure can be compromised.

In such cases, amino acids present in shampoos, conditioners or leave-in masks can help repair this damage by replenishing the protein content of the hair.

Peptide Bonds


Peptides are quite the rage in the skincare world. After all, they’re best known for stimulating cell turnover and reducing the signs of ageing. So the term is not new. But in the haircare space, peptides also play a crucial role in forming the structure and strength of your strands. Peptides are essentially hair’s smallest molecular structures. Keratin, as mentioned before, consists of long chains of amino acids linked together by peptide bonds.

These bonds help prevent hair from breaking or becoming damaged easily. However, external aggressors such as chemical treatments can break peptide bonds; the amino acid chain is then broken and the hair’s molecular structure is compromised.

Additionally, peptide bonds contribute to their elasticity and flexibility, allowing them to withstand bending and stretching without breaking. One of the easiest ways to know whether your hair is damaged or not is by performing the elasticity test. Grab a strand of wet hair and pull it lightly. If it doesn’t bounce back or break, it is damaged.

Therefore, various treatments often target peptide bonds to strengthen and repair damage.

Introducing the L’Oréal Professionnel Paris Absolut Repair Molecular Range

When amino acids are compromised or the peptide bonds are broken, it results in damage at a molecular level. Thus, the only complete repair solution is linking peptide bonds with amino acids to form structured peptides. Thus, peptide repair offers a more complete solution than bond repair and not only takes care of brittle, weakened hair structure but also reconstructs the inner hair structure.

The L’Oréal Professionnel Paris Absolut Repair Molecular range helps do just that by decomposing peptide components and re-injecting them into the hair fibre. It repairs up to two years of damage in just one use, and that too for any hair type!

The range is formulated with an ultra-concentrated selection of 5 amino acids and up to 3% peptide bonders. These supplement the degradation of amino acids and rebuild the molecular structure. So while your hair is getting all the nutrients it needs to address damage, it also repairs inner damage with strength, shooing away concerns like lack of elasticity, lack of movement and fibre weakness.

Beyond its ability to transform the hair from dull to healthy, it features fragrant head notes of bergamot, calone and white lavender, heart notes of everlasting flower and salt flower, and base notes of vanilla, sandalwood and vetiver.

Let’s dive a little deeper into the range.

To get the true Absolut Repair Molecular experience and results, visit your nearest salon monthly for the Molecular Deep Repair treatment. This is a completely sulfate-free treatment that repairs damaged hair from within. It also boasts the highest concentration of peptides bonder (3%) and 5 amino acids.

And of course, this treatment starts with a personalized, professional diagnosis – the elasticity test done by a hair expert – to determine the exact level of damage in the hair.

In between treatments, make sure to keep your hair damage-free with the Absolut Repair Molecular home-care range.

Sulphate-Free Shampoo: Infused with peptides bonder and amino acids, this sulphate-free formula not only cleanses but also imparts an impressive 86% increase5 in smoothness.

Rinse-Off Serum: Formulated with 2% peptides bonder and 5 amino acids, this serum restores hair strength by 97%6, ensuring resilience from within.

Leave-In Mask: Offering up to 230°C heat protection7, this leave-in mask shields the hair while harnessing the power of peptides bonder and amino acids to nourish and fortify the hair fibre.

So in an age where hair damage is such a huge concern, the best way to maintain your strands and reverse years of hair damage is by using the L’Oréal Professionnel Paris Absolut Repair Molecular range as an antidote!
