[Question] How can I protect my hair that keeps breaking off?

The unhealthier the scalp, the more it depends on the weather and condition
They say the condition of the hair changes a lot.
The temperature has started to rise a lot lately, and
It is the start of dry and humid weather, so perhaps that is why
My hair keeps breaking off more and more every time I comb it these days.
Is there no way to keep it healthy? Even if it isn't silky smooth hair
I've been trying to protect my hair by cutting down on dyeing and perming, but I wonder if aging is starting.
I'm worried that the hair loss counterattack might be starting.
I wonder if the hair is breaking because the washing and drying process is wrong, or if I need to cut off the damaged hair.
I am seeking help on how to grow healthier.
