My family has been using Soladay toothbrushes for a long time, but recently my parents don't seem to use them, so when I asked them, they said that brushes with normal hardness are hard.
Certainly, with regard to the brush that says “normal,” I thought this one was also a little stiff, but if you are an elderly parent, I understand that it feels like a stiff brush, and as a result of investigating if there are no types, it turns out that there are softer brushes, and there are also those called fine hairs, so I bought both of them.
Since I softened it, my parents began to use it, so I thought I should have looked it up sooner.
