Câu hỏi:

How does the cát of a dũa móng tay affect the móng tay tự nhiên? Are there grits that shouldn’t be used on the natural nail and why? I’ve been told not to use any coarser than a 180 grit on natural nails. But I don’t know if this is supported by science.

Trả lời:

The “grit” describes the average size of the mài mòn particles. The lower the grit number, the bigger the abrasive particles on the file. A 60 grit particle is a little more than three times larger than a 180 grit and five times larger than a 240 grit abrasive particle. That may not sound like much difference. But if you are 5 feet tall, someone five times larger would be 25 feet tall. It’s like comparing a Volkswagen with a two-story house. A good rule to remember is the lower the grit, the bigger the abrasive particle, and the deeper and wider the scratch it will leave on the tấm móng tay.  

In my opinion, the natural nail can be properly prepared using a 240 grit. Of course, if the nail plate is properly cleaned and prepared. This requires removing oils, debris, and dead lớp biểu bì tissue from the nail plate’s surface since these can block the adhesion of all lớp phủ móng tay.

Problems develop when the nail plates are not properly cleaned and carefully prepared. This is one reason why I recommend that clients wash their hands with a clean and đã khử trùng nail chải BEFORE the service begins to remove surface oils as well as bacterial and fungal organisms. Rather than take the time to prepare the nail plate properly, some choose to do their nail prep work with a 180 grit file. This will remove surface oils along with a few of the upper layers of the nail plate. It can result in excessive thinning of the nail plate. This is especially more likely if proper care isn’t taken and too much downward force is applied.

Anything lower than 180 grit is risky business when used on the natural nail plate. It is very likely to lead to excessive damage. In my view, the only reason for using grits lower than 180 is to reduce the thickness of the existing nail coatings for quicker dung môi removal. Reducing the lớp phủ thickness decreases soaking time. This should be done cautiously to avoid damage to the underlying nail plate and bed.

There are many different brushes needed by a nail professional. e.g an L&P brush which needs to be a natural Kolinsky sable brush so it can hold the monomer liquid and pick up the polymer powder as a bead; UV gel brushes are usually nylon or other man made fibre. Nail art brushes are usually a variety of natural fibres. All have different uses and all much be kept clean to provide long usage.<\/p>\n<\/div>","cmtt_5967cb8b3d81b440a65f0791b8c6ea9f":"

Solvents<\/div>
\n

Solvents (in the context of nail products as water is a solvent) are chemicals such as acetone, ethyl acetate, methyl acetate, butyl acetate, toluene. They are able to dissolve certain products or break their bonds. They are commonly used in nail polishes and nail polish removers. They are usually volatile and are the method used to dry nail polish as they keep the product liquid until they are exposed air and will evaporate and leave the pigments and other ingredients (such as plastisers etc) as a nail coating. They are also used in nail plate dehydrators to cleanse and degrease the nail in the preparation for a coating application.<\/p>\n
\n

Pathogens (with the possible exception of fungal spores) are unable to survive in a product with a high level of solvents. This is why it is safe to use nail polish on several clients without spreading any pathogens<\/p>\n

Nail Buffing\n

This is a process using an abrasive. It could refer to using a buffer (usually with a high grit of around 240) to shape and refine a nail coating or overlay.

Grit<\/div>
\n

This refers to an abrasive. Many different files and buffers are used by a nail professional for different purposes. The 'grit' denotes the level of abrasiveness. The lower the number the more abrasive the file or buffer; the higher the number the less abrasive. 100 or 180 grits is commonly used to shape and refine a coating or overlay. 240 is the lowest grit that should be used on a natural nail as any lower can cause too much damage. <\/p>\n<\/div>"}}; -->
