HAIR: THE BASICS
Protein capital
Hair is mostly made up of keratin, which is a protein. This constitutes its protein capital (in the same way that you have sun capital!).
Initially, your hair grows from the root and then forms a keratin shaft with 100% of its protein capital, meaning that it has all the capillary bonds necessary to be healthy.
In particular, it has disulfide bridges , which are formed between two sulfur atoms from the amino acid cysteine present in keratin chains, and which are responsible for the strength and structure of hair.
But, over the course of life, hair is brushed, colored, bleached, straightened,...and with each action, the hair becomes fragile, the cuticle scales open and the disulfide bonds break.
The hair then becomes dull and brittle.
The case of curly hair
Disulfide bonds are responsible for the strength and resilience of hair, as well as its natural shape . Therefore, the more disulfide bonds a hair has, the curlier it will be! Curly and frizzy hair therefore has more disulfide bonds than straight hair.
But, when we straighten or smooth our hair, we apply products or heat and we permanently break the heart of the hair, because we destroy these capillary bonds.
To rebuild damaged or relaxed curls, it is important to adopt treatments that regenerate the hair at its core.
Focus on bleached hair
Bleaching uses a powerful oxidizing agent to break down the chemical structure of melanin, the pigment that gives hair its color. However, during the process, bleaching also oxidizes disulfide bonds, thus altering the structure and strength of the hair fiber .
Hair then becomes weakened, dry, and brittle. It also becomes more sensitive to UV rays and is therefore prone to yellowing.
It is therefore important to use suitable hair care products to restore their protein capital , regenerate damage linked to discoloration, and prevent yellowing of the hair.

Good habits to adopt on a daily basis
To maintain your protein capital and healthy hair, the ideal is to avoid external aggressions as much as possible!
Limit the use of straighteners and hair dryers, avoid bleaching and other chemical treatments.
Also protect your hair from UV rays , especially in summer, by using a hat or scarf.
Finally, apply gentle cleansing treatments , without silicones or sulfates, which will either protect the hair from daily damage or repair it if it has not been sufficiently protected.
LAO Care has specifically developed two hair care ranges to protect or repair hair, depending on its daily needs.
LAO Care: the hair and scalp care expert
Step 1: Balance the scalp
A healthy scalp is essential for maintaining healthy hair, so it's important to take care of it!
To this end, LAO Care has developed all of its sulfate-free shampoos ; the cleansing base is derived from sugar and helps to respect the scalp's balance. Each shampoo also has a high concentration of hydrosol adapted to each scalp type, and which has a measurable and long-term effect on the majority of scalp problems, such as dandruff for example.
Our Purifying Shampoo contains organic nettle hydrosol, known for its sebum-regulating properties . It is ideal for regulating oily scalps and leaving hair clean for longer.
*Use test on volunteers for 28 days .
The Nourishing shampoo contains a high concentration of organic lemon balm hydrosol, known for its soothing properties, and will be ideal for rebalancing sensitive scalps and softening hair .
*Use test on volunteers for 28 days
Step 2: Protect the hair: LUMINACARE ®
As explained previously, hair has a protein capital and, day after day, this capital diminishes: it becomes dull, splits and breaks.
All year round, UV rays and pollution oxidize hair bonds and accelerate this process.
LAO Care has developed a dedicated technology to protect hair lastingly from damage caused by UVA and pollution : LUMINACARE® technology .
Thanks to our patented technology since 2021, hair is protected from UVA rays, pollution and fine particles from the first wash.
The protein capital is thus preserved, and the hair remains healthy for longer.
This technology has been incorporated into our entire Daily Protect range , consisting of the Purifying Shampoo , Nourishing Shampoo and LAO Care Conditioner .
Every hair has its own story.

Step 3: Regenerate keratin: PEPTICARE ®
If unfortunately the hair has been damaged by heat, UV rays, bleaching etc. and the protein capital is reduced, it is fortunately possible to regenerate it in a sustainable and quantifiable way!
Indeed, LAO Care has developed its new PEPTICARE® technology , for which a patent was filed in 2024, specially designed to regenerate the disulfide bonds of the hair fiber .
100% derived from natural and French resources , this technology is biomimetic, meaning that it is composed of the same amino acids that make up the structure of keratin .
This technology is therefore very easily assimilated by the hair fiber, and allows the disulfide bonds to be reconstituted and the keratin to be regenerated sustainably from the first application.
All About Natural Bonding: Repairing Broken Keratin Bonds
Hair suffers daily damage that breaks the keratin bonds.
And, even if it is not irreversible, most of the current brands on the market are content to camouflage this damage, by only “repairing” the fiber on the surface.
This is the case with many hair care products, which are either composed of silicones for conventional products or oils for natural products.
These products will only beautify the hair temporarily, because as soon as the hair is washed, the benefits disappear and the hair is left as damaged as it was at the start...
Claims for compensation for these treatments are often quite weak, because they are mainly based on subjective consumer tests, and not on quantitative instrumental tests.
To truly and lastingly repair hair, LAO Care has developed the Intense Protein Bonding range , made up of our PEPTICARE® technology, to repair hair from the inside by lastingly regenerating broken keratin bonds.
What makes INTENSE PROTEIN BONDING different
Our Intense Protein Bonding range is 100% natural in origin , with unique, biomimetic technology .
Effective from the first application, it repairs the hair fiber in depth, for healthy and lasting regeneration .
This range has also been the subject of numerous instrumental tests , carried out by independent laboratories, on strands of hair subjected to heat and bleaching, to prove its effectiveness:
(1) Instrumental test on strands of bleached hair then washed with the complete routine.
(2) Instrumental test on strands of hair subjected to heat then washed with the complete routine.

FAQ
How to get your curls back naturally with the INTENSE PROTEIN BONDING range?
Curly hair is curly due to the strong presence of disulfide bonds between the keratin fibers. When curly hair is straightened or relaxed, these disulfide bonds are broken, and the hair fiber becomes straightened. However, this alters the structure of the keratin, thus weakening the hair.
Our Intense Protein Bonding range , 100% natural origin, has been specially developed to repair disulfide bonds (+73% of bonds repaired in one application). By using this range, the keratin will therefore regain its initial structure, and the hair will regain its natural curls.
How to prevent your blonde from turning yellow after bleaching or highlighting?
Bleached blonde hair is more sensitive to UV rays and is therefore prone to yellowing.
Our Intense Brotein Bonding range helps regenerate protein capital and strengthen the hair fiber, which will revive and maintain the blond color of bleached hair.
