Filing in one direction?

Câu hỏi:

Does filing in only one direction, towards the center, really help the nail?

Trả lời:

I have not found this to be true. I have tested this concept by using high magnification photography to record the results of various filing techniques. After examining tấm móng tay filed using various mài mòn grits and filing techniques. I didn’t observe any differences in the condition of the móng tay tự nhiên plate when comparing filing in only one direction with doing it in a back-and-forth fashion.

This study was conducted on normal, healthy nail plates, so perhaps there may be a difference if the nail plates are damaged, but this appears to be a myth. I’ve seen nothing to support the claim that filing in only one direction provides any benefits.
