I have a question regarding rogaine. I have thinning in the crown and front of the head too. I have read that rogaine can be beneficial for retarding additional hair loss anywhere there is hair. Thus, I split the 1 ml dose throughout my scalp rather than just concentrating it on the crown.
Would this stop the effectiveness of rogaine? I suppose I am not supposed to use more than one ml.
I would use the dose listed in the directions that came with the product that you purchased. You can put Rogaine on your crown and front area of your scalp, but it should only be placed in the areas where you want the benefits and not put in areas where the hair is good. As you know, it has not been shown to be as effective in the frontal areas.
I suspect you can use more than 1 ml, but there is a small risk of your body absorbing too much and you experiencing systemic side effects (such as headache, fainting, etc). I would think this risk is low, but it is something to think about.
If you are concerned you should ask these questions to your doctor and get a good medical physical examination to make sure you will have no issues. I am not your doctor and this is not a place to get personalized medication use advice, simply because I do not know your medical history.
