Keratin: origin, benefits and deficiencies

Keratin : the ideal solution to target hair loss and strengthen the hair fiber. 

In supplementation and hair care, the intake of high doses of keratin stimulates hair growth, repairs damaged hair and nails and restores strength, shine and elasticity to hair. 

What are the effects of a deficiency on hair health?

The lack of this protein in our hair must then be compensated again using supplement hair food and cosmetic products for damaged hair such as shampoo, conditioners, creams or moisturizing masks based on this element, so that the hair fibers can be repaired and the lengths regain a smooth and shiny appearance as well as optimal hydration.

1. Type alpha

Origin and extraction of alpha

Alpha keratin is the most common form and is found primarily in hair and nails. It is extracted from animal sources such as sheep wool. The extraction process involves cleaning and purifying the wool to obtain a pure, bioavailable protein.

2. Beta type

Origin and extraction of beta

Beta keratin is less common and is found primarily in feathers and scales. Its extraction requires a denaturation process to transform the structure of the protein, making it usable in hair products and dietary supplements.

3. Hydrolyzed Keratin

Origin and extraction of this form

Hydrolyzed keratin is obtained through a hydrolysis process that breaks down the protein into smaller molecules, making it easier to absorb into the hair and skin. This form is often used in hair products for its restorative and moisturizing properties.

4. In liquid form

Origin and extraction of this form

Keratin in liquid form is commonly used in hair care for direct application to the hair. It is extracted from animal sources and made into a liquid solution that can be easily applied to fill gaps and strengthen the hair fiber.

5. Pure

Origin and extraction

Pure keratin is ideal for intensive treatments. It is often extracted from the wool of sheep or other animal sources and undergoes a rigorous purification process to ensure high quality and maximum effectiveness.

Pure for hair

The pure version of this protein is ideal for intensive treatments. It is often used in hair salons for deep treatments that bring damaged hair back to life.

1. Shampoo

Sulfate-free shampoo

Sulfate-free shampoos enriched with this beneficial ingredient are recommended to preserve hair health while gently cleansing it. They help maintain hydration and strengthen the hair fiber.

2. Hair care

Hair care

Hair care products, like masks and conditioners, are essential to deeply repair and nourish hair. Thanks to keratin, they bring shine, softness and strength to the hair.

What are the benefits for hair?

The benefits of this protein for hair are numerous. It helps repair damaged hair, reduce frizz and improve overall hair texture. By strengthening the hair fiber, it also helps prevent breakage and promote healthy growth.

1. Extraction for supplementation

The extraction of animal keratin can be done from horns and hooves, but can also be obtained from sheep or apalga wool.

This is the case for our Keratin Absolute whose keratin comes from the wool of sheep raised outdoors and shorn humanely in the presence of a veterinarian and according to very strict specifications.

For optimal results on the scalp and hair fiber, our hydrolyzed keratin is manufactured using a natural extraction process and patented to obtain soluble tri-peptides with an amino acid profile identical to that of humans.

2. The benefits of supplementation

For hair

Tests have shown the effectiveness of this structural protein on hair at a dose of 500mg per day. It is therefore interesting to take Keratin Absolute, a 28-day treatment, at each change of season, for at least 3 months in a row, especially for weakened hair.

For nails

This protein is also a building block of nails, and keratin supplementation will help to achieve harder and less brittle nails.

Some advice

To promote the results of capsules of this substance and fight against deficiencies, it is advisable to reduce heat sources such as straighteners or hair dryers, to massage the scalp a few minutes to stimulate the bulb and promote breathing of the scalp and to carry out vegetable oil baths such as castor oil, argan oil or oil coconut.

1. Duration of the treatment

All D-LAB formulas have a treatment duration of 28 days which corresponds to the lifespan of our cells. 3 months or 3x28 days, this is the duration necessary to activate the cellular memory in the hair bulb and have more visible and lasting results on the fiber. 

To provide the maximum amount of active ingredients to the bulb and optimize the results, you can do up to 6 months of treatment maximum, to prevent the bulb from getting tired.

2. Food and nutrition in addition to the treatment

Where to find it in food?

The best way to nourish keratin is to eat a healthy and balanced diet that provides vitamins, minerals, amino acids and essential fatty acids. 

The best nutritional sources for keratin are: fruits and vegetables, preferably seasonal, vegetable oils, oleaginous fruits and fatty fish for omega 3, 6 and 9, and proteins (vegetable or animal).

What are the best natural ingredients to boost production?

To have beautiful hair, we must act from the inside by providing the nutrients that make up the hair fiber, because nutrition happens at the level of the bulb. External treatments only allow action on the outer layer of the fiber to protect it. 

It is therefore necessary to provide daily and in sufficient quantity all the essential nutrients, namely trace elements such as magnesium, iron, copper, B group vitamins and sulfur amino acids such as l-cystine, l-methionine, m -lysine. 

These nutrients are provided by a balanced diet but also by nutritional supplementation since, due to our modern life, food is unfortunately no longer enough to provide them in sufficient quantities.

3. Are there any contraindications to use?

It is very important before carrying out various keratin treatments and care to find out about the origin of this keratin as well as its dosage. 

If your hairdresser has difficulty providing you with information, then make your request to the manufacturer who must clarify for you the origin of the keratin used in its products.
