Are there any good ways to deal with or tips for the side effects of minoxidil?

Minoxidil is really good for hair growth, but,

The part I am most concerned about is the side effects.

From what I've found out, I've heard that the side effects vary slightly depending on whether it is a topical or oral formulation.

1. Irritation and shedding from topical minoxidil
When using liquid or foam types
I've heard that it is common to experience irritation such as scalp itching, redness, or dandruff.
If you experienced skin irritation, I am curious if it was alleviated when you switched to the foam type.
And those who experienced the 'shedding phenomenon,' where more hair falls out in the early stages
I would also like to know how long it usually takes for it to subside.

2. Systemic symptoms and hirsutism of oral minoxidil
It seems like a lot of people are taking oral minoxidil these days,
Has anyone experienced symptoms such as swelling (edema), dizziness, or heart palpitations?
I am also curious if hypertrichosis, where hair grows longer on the hands, eyebrows, or body, occurs more commonly than I thought.

3. How to deal with side effects
    Do you happen to have any tips on how to resolve side effects experienced while using the product by reducing the dosage or changing the formulation?

They say that hair loss management is a long-term battle, so the initial choice is really important.

It would be a huge help if you could share your valuable actual user reviews and a line of advice.
