It's perfectly fine! I had a MILLION questions too lol. I rub a small amount on my scalp in sections & leave it on. I don't add too much because it causes headaches. It rubs right into my scalp & isn't greasy or drying for me. It doesn't have a smell either so I just keep reapplying it everyday because it soaks up into my scalp. I wash my hair twice a week. Search up miconazole nitrate on nc or google & read everyone's reviews & how they dilute their mixture. Some people use different oils to prevent headaches. You can see how long ladies' hairs have gotten on YouTube as well.
