Nail Hardeners For Brittle Nails - best facial anit agingl skin care products
Nail hardening agent to harden and solidify broken, brittle, split or peel off nails by strengthening nails from the inside or forming a thick protective coating on the surface.
Definition: What is the nail hardening agent?
Nail hardening agent is a cosmetic formula for fragile nails to make nails more resistant to breakage and prevent cracking and peeling.
Nail hardening agent is also called nail strengthening agent.
It is important to distinguish between another nail product called nail conditioner.
Nail conditioners are different from nail hardening agents because they are moisturized with oil and nourished with vitamins but not hardened.
However, the nail hardening agent contains substances that Harden and solidify inside the nail or on the surface of the nail.
History: What is the origin of nail hardening?
In the United States, the first interest in nail hardening is around 1792, a combat movement called "rough and swollen.
Participants will live with their nails gou.
To prepare for the fight, they hold their nails on open fire to harden them.
Later, in the 1960 s, with the continuous development and expansion of the cosmetics industry, nail hardening agents contained at least 10-
Percentage of formaldehyde solution.
Later, the FDA (Food and Drug Administration) recalled these products due to the reported disease and formulated a requirement that formaldehyde concentrations not exceed 2-
Percentage of nail hardening products. The 2-
There is still a percentage limit today.
What is the reason for the crispy nails?
There are three main parts of a nail: nail bed, nail matrix and nail plate.
The nail bed is the skin under the nail and contains blood supply that delivers protein and nutrients to the nail matrix.
The nail matrix found at the bottom of the nail uses these proteins and nutrients to produce most of the collagen cells.
With the production of the Kerins, the old ones advance forward to form nail plates (hard parts of the nails), becoming compressed, flat and translucent.
The nail plate will become brittle and will fall off, peel off or crack.
Stripping usually occurs in the horizontal layer, while longitudinal splitting occurs in the nail.
The condition of crispy nails including splitting and peeling is known as nail fish cracking.
Fragile nails can be dry and fragile, unable to maintain enough moisture, can also be soft and fragile, experiencing excessive moisture.
In order to determine whether the environment is the reason the nails become brittle, the nails should be compared with the toenails.
If the toenails are strong, the crispness is caused by external factors.
External factors include washing or bathing, changes in temperature and humidity, exposure to chemicals, or removal of nail polish.
Because the nails are very easy to absorb, washing or bathing can cause crispness, which is actually ten times the skin.
When water is absorbed into the nail, the horny cells expand.
Nail cells contract after drying.
This repeated expansion and contraction can lead to the brittle of the nail.
When the humidity level of the surrounding environment changes, the same type of strain (expansion and contraction) may occur, usually due to changes in the external temperature.
Chemicals found in detergents, cleaning products, and nail polish remover can dry or damage the nails and cause crispness.
It is worth noting that acetone-
The free nail polish agent will only reduce some problems compared to the one containing acetone.
The use of an alcohol disinfectant can cause the nails to dry and, as a result, the nails to become brittle.
An unfortunate habit of removing nail polish can also cause brittle hair;
With the addition of nail polish, the top layer of the horny cells also began to fall off.
There are other reasons why unhealthy nails become brittle, peeling or cracked, however, these reasons will be discussed later.
Function: How does the nail hardening agent work?
There are two kinds of nail hardening agents: Cross type
Connect the nail hardening agent and strengthen the nail hardening agent. Cross-
Link the nail hardening agent to actually penetrate the nail, change the frame of the nail Horn (protein), and provide more structural support from the inside.
The reinforcing nail hardening agent does not penetrate the nail, but covers the surface of the nail with a thick, hard or flexible protective covering.
Fortifier does not permanently change the condition of the nail like a cross
Link hardening agent can.
Once the fortifier is removed, the nail goes back to its previous state.
(Note: For the purpose of explanation, in this hub, the enhancement hardening agent has been further subdivided by function. Cross-
The nails are almost entirely made of the collagen (protein) fibers that form a matrix of connections within the nail plate. A cross-
Link is a bond that links one protein chain to another by forming a bridge between the two.
Chemicals can lead to cross
The most common chemical used to increase the number of crosses
The link key inside the nail plate (so that the nail is thicker) is formaldehyde/formaldehyde.
Formaldehyde/formaldehyde penetrates the nail plate and performs a chemical reaction to naturally discovered proteins (toxins), resulting in an increase in the amount of bonds (bridges) between protein chains.
This hardened the nails.
Notes on formaldehyde/formaldehyde INCI (International naming of cosmetic ingredients) requires manufacturers to list formaldehyde under the name of formaldehyde.
Although formaldehyde does contain trace amounts of formaldehyde (formaldehyde is actually a combination of water and formaldehyde to form a completely different substance), it remains at a safe level according to FDA standards of no more than 2-
Percentage solution of formaldehyde in nail hardening products.
Most nail hardening agents contain formaldehyde instead of formaldehyde.
Although the FDA believes this is safe, this does not solve the problem of allergic to formaldehyde/formaldehyde when in contact with the skin.
In addition, formaldehyde/formaldehyde is a positive Crosslinking agent. Too many cross-
The link in the nail plate can cause excessive hardening of the nails, resulting in breakage and crispness.
It is recommended to use only formaldehyde/formaldehyde nail hardening agent on a regular basis or alternately with non-formaldehyde
Hardened bottom coating.
A second chemical that can cause Cross
The link that occurs in the nail plate is DMU (dimethyl urea ).
It works exactly the same way as formaldehyde/formaldehyde, but has two advantages.
1) The DMU does not produce too many crossover
Links to frequently used and over-hardened nail plates.
2) the sensitivity of DMU is low (allergic reaction is easy ).
Although the nail plate is mainly made of collagen, there is mineral calcium precipitation attached to the protein.
Fluorine is a chemical that binds to calcium molecules.
The application of a nail hardening agent containing fluoride causes a chemical bond between the fluoride in the product and the naturally occurring calcium in the nail plate. CaF (calcium-
Fluorine) bonds occur on the surface of the nail.
Fluorine does not penetrate nail horn like a cross
Link hardening agent can.
A protein is composed of long chains of amino acids (called peptide bonds) that are connected together to form Silk (fibers ).
A protein hardening agent such as a protein to form a network
Like a protein filament (fiber) network with staggered nail surfaces.
In addition, the peptide bond in the protein can be decomposed by the process of hydrolysis into a single amino acid unit.
Hydrolysis cereals and plant proteins such as soybeans, wheat and corn are also formulated as nail hardening agents.
Due to their hydrolysis, their protein peptide bonds are broken down into individual amino acids or partially connected amino acids floating in the product.
When the product is applied, the amino acid will re-
Form New protein filaments (fibers) and form networks
Like a network on the surface of the DingTalk.
These filaments (fibers) are microscopic, but they do harden the nails.
Protein durators do not penetrate nails because their molecules are too large to penetrate them.
Some nail hardening agents contain trace amounts
A fiber made of nylon, silk, or fiberglass.
These functions are the same as those of the protein hardening agent;
They make up a network.
Just like the staggered fiber network on the surface of the nail. The micro-
The fiber is chosen for its strength.
Nylon is a tough, resilient synthetic polymer with a chemical structure similar to that of a protein.
Silk is a natural material produced by insects. it is known to be strong and durable and not easy to break.
Made of fiberglass, the fiberglass is sturdy and durablebrittle.
The mineral hardening agent forms a hard protective cover on the surface of the nail, made of minerals such as diamond powder or calcium.
Diamonds are considered the hardest known substances.
Calcium makes bones strong and hard.
These two minerals form a hard, thick shield on the surface of the nail for reinforcement.
Audience: who is good for nail hardening agent?
In addition to the environmental factors that led to crispness mentioned earlier, medical conditions may also be the cause of breakage, division and peeling.
People who do not have these medical conditions side by side except for environmental factors may cause nails to become brittle due to genetics (genetics) or simple aging.
It is estimated that about 20-
As a percentage of the population, nails become brittle.
There are two types of nail hardening agents available on the market for people with crispy nails.
Connect the protein inside the nail with those that strengthen the nail by forming a thick protective coating on the surface.
The benefit of nail hardening agents is that they can repair crispy nails that break, crack or peel off.
