I have some questions on the use of Regaine for women. Do I apply 1ml Regaine to one single spot or in different areas. Is the hair parted down the middle and the entire dose applied or parted in 6 different places with 1 spray in each place. I am confused on how to apply and does it need to be rubbed in or just applied. How does it reach all areas of the scalp if applied in only one place. Thank you for any and all info you can offer. I have overall thinning but mostly on the crown. This is genetic. I am 53 years old.
