How do I use Rogaine with Retin-A?
This can be tricky. As stated above, you can not just mix Rogaine in with Retin-A. If you have purchased precombined Rogaine and Retin-A, apply it as instructed. If you purchase them separately, they must be applied at separate times. Some people apply the Retin-A and then the Rogaine, some the Rogaine then the Retin-A. Some find if they apply one after the other it causes irritation. You have to find what works for you. The general theory is that you should apply one, wait until the solution has dried COMPLETELY (usually 15-30 minutes), then apply the other. You still have to apply Rogaine twice per day. Whether you apply Retin-A twice per day is up to you, however it is not recommended that you use Retin-A in sunlight. If you do not experience itching or scaling by applying twice per day, go for it. Most people apply Retin-A, then Minoxidil, under the theory that the Retin-A will increase absorption of the minoxidil.
