Pain-free
The Shikahama Method enabled "the nail correction without pain"
by following three mechanisms.
Moisture absorption
When the nail absorbs moisture enough, it softens to about 1/4.
This is the same with the hardness of glass becoming a plastic bottle.
You will feel no pain when it's softened enough.
The nail pressurizer
You will feel pain in the contact point between the nail and the fresh when the nail is lifted up.
The nail pressurizer pinches the contact point to relieve the pain.
Softened skin
By soaking to warm water, the skin swells up as well.
As the skin becomes insensitive as it swells, the pain becomes less.
