Can propylene glycol (in Minoxidil) damage my brain when applied to my scalp?

No, it won't damage your brain. I suggest seeing an expert to evaluate your condition and consider the best treatment options. Minoxidil works best in combination with other non-invasive options like PRP/progesterone. See an expert. Best, Dr. Emer

Minoxidil
is topical, there are quite few barriers to get through before a topical
medication reaches the brain.  Most
people tolerate Minoxidil quite well.

as it is applied topically it will have no affect on your brain. it can cause some redness and irritation to the scalp where it applied.

The amount of propylene glycol in minoxidil will not damage the brain. It can sometimes irritate the skin. It does not damage the brain.

The propylene glycol (in Minoxidil) may cause allery to your skin but does not any affect on your brain .

You should not have an negative effects from the propylene glycol in Minoxidil.  However, if your have sensitivity to the product, many patients have success with a minoxidil foam.

I am not aware of any studies that indicate that propylene glycol has any negative effects on the brain.  I recommend that you continue to see your physician on the best course of treatment for your hair loss.

The propylene glycol (in Minoxidil) is harmless to most people if they are not allergic as most problems are topical and do not go to the brain
