Which is Preferred: Rogaine Foam or Liquid Formula?

Q: Do you think there is a difference in the efficacy between the 5% Rogaine foam or liquid formula? — N.N., Dallas, TX

A: In theory, the foam should be as effective as the original solution (liquid). However, an important part of the efficacy is getting the medication directly onto the scalp – rather than just on the hair.

For patients who are applying the medication to areas with a significant amount of hair, using the solution with a dropper applicator enables the medication to best reach the scalp. Because of this, I prefer that patients use the solution with a dropper applicator if they are using the medications in areas with a significant amount of hair. If patients find the solution irritating to the scalp (or too messy) and the foam less so, then using the foam is better than nothing.

Allergic Reaction to Rogaine Liquid but Not Foam?

Q: Our dermatologist originally suggested our son use the 5% Rogaine and he developed an allergic reaction to it. Allergy tests confirmed it was the propylene glycol causing the reaction. I understand that Rogaine foam has 5% minoxidil in it but no propylene glycol. Is that correct? — B.M., Lower East Side, N.Y.

A: In addition to minoxidil 5%, Rogaine Foam contains: butane, butylated hydroxytoluene, cetyl alcohol, citric acid, fragrance, glycerin, isobutane, lactic acid, polysorbate 60, propane, purified water, SD alcohol 40-B, stearyl alcohol — but no propylene glycol.

How Long After Hair Transplant Should I Wait Before Continuing Treatment with Rogaine?

Q: I stopped using Rogaine for my hair transplant, when can I start using it again? And would it be any different with the new Rogaine foam. — J.N., London, United Kingdom

A: I would wait at least 7 days to use Rogaine (minoxidil) in either liquid or foam.

The foam has less alcohol and can be irritating when applied to open wounds, but should be fine one week post-op.
