What is the best dosage of Rogaine? Once or twice daily?

The  half-life of Rogaine absorbed through the scalp is approximately 20 to 22 hours. Therefore, there isn't a significant difference between using it once or twice a day as long as you're using the 5%. I would recommend purchasing a microneedle roller with pins .25 to.3 mm and rolling the scalp prior to application of the Rogaine. It stimulates hair growth and increases absorption.

Rogaine's recommended dosing schedule is generally twice daily. I do think it is effective even when used only once daily, and this is important, because many people have trouble using Rogaine twice daily. I recommend that patients stay on Rogaine as long as possible because I do not believe it provides long-term results when used only for short periods of time.Rogaine should be part of a multi-modality treatment plan for hair loss that also includes PRP, nutritional supplementation, laser/light therapy, etc.Be sure to see a hair restoration specialist to review all of the options in detail.All the best,

Minoxidil 5%.If you can tolerate using Minoxidil 2x a day then you definitely should. In the morning and in the evening. As far as stopping the use of minoxidil this may result in your body naturally catching up to your normal progression of hair loss so I  recommend for you to keep using it.
