Excuse me, how to restore the peach comb if it is deformed?

My mother bought me a mahogany comb before, and then when I washed my hair, the water temperature was relatively high, so I soaked my hair in water without much thought, and put it on the windowsill after washing. As a result, when I saw it the next day, it was dry, and my two heads were upturned like the moon. I was worried. How did this happen? Although it can be used, it is not convenient. Later, I put the crescent moon on the table.
