Hair tonic or ampoule on dry hair

I feel like the amount of hair falling out has increased significantly, so I am using tonic and ampoules before it gets worse.

It is generally common to use it after washing your hair and drying it to some extent.

Sometimes I forget, so I use a hair ampoule or tonic after washing and drying my hair.

Is it okay to use it like this? It’s not something I do while sleeping, but I’m curious if I’m using it incorrectly.
