I am curious about the duration of hair loss treatment for frontal hair loss after childbirth.

I expected some hair loss after giving birth, but I'm worried because my bangs look much thinner than I thought.
At first, I thought it would naturally go back to normal over time, but since my bangs aren't the same as before, I find myself self-conscious when taking photos and being careful when tying my hair up.

Taking care of my children always puts my scalp and hair care on the back burner, but lately I've been looking into hair loss treatments because I'm worried it might get worse if I leave it as is. I know people say postpartum hair loss recovers over time, but if my hairline keeps looking thin, I feel like I need to start taking care of it.

Has anyone here received hair loss treatment for frontal hair loss after childbirth? I am curious about how long the effects last. I would like to know how many sessions are needed to feel like hair loss has slowed down, and how long it takes for new hair to grow in. Since I don't think the treatment is a one-time thing, I am most curious about the treatment cycle and duration of the effects.

Since it is not easy to go to the hospital while raising a child, knowing how often I realistically need to visit is also important. ^^ It would be helpful if those with experience could let me know the duration or frequency of treatments.
