I added 5 mg oral minoxidil to my regimen 6 weeks ago and just very recently noticed a huge improvement in hair thickness AND some regrowth along the hairline. I was thrilled, considering I have had nothing but loss and recession for 9 straight months. Unfortunately, I started getting heart palpitations and edema right around the time I noticed regrowth . I'm going to take a few days off, supplement with topical minoxidil in the meantime (which never really worked for me in the past), then restart at a lower dose. Has anyone had success with very low doses of oral minoxidil? Has anyone supplemented their oral minoxidil with topical minoxidil?
