FUE transplant 7 weeks Post Op - Minoxidil redness

Minoxidil can certainly cause irritation and redness. Generally it won't help with transplanted hair however it will work on the thinning, miniaturizing hairs. I recommend following up with your Hair Transplant Physician to further discuss whether to continue treatment or not.

If you are having issues with medication, it is best to contact your your doctor as soon as possible.  Minoxidil can cause irritation for some people.

At 7 weeks post procedure the scalp is essentially healed but may still be slightly sensitive.If you are using it twice a day you could try decreasing to once a day and see if the irritation subsides.You could also try the women's formulation which is a 2% concentration rather than 5%.It may take some trial and error-if the redness/irritation persists than Minoxidil probably is not for you.Finasteride(Propecia) and Low Level Laser Light therapy are 2 effective alternatives for preventing hair loss.

I'd recommend talking to your doctor about it, but yes, consider stopping using it in the meantime. Those are common side effects from Minoxidil and it doesn't help with transplanted hairs anyways, just your natural ones. 

Minoxidil can cause slight irritation and redness. I would suggest stopping the Minoxidil and consulting with your surgeon. 

Sometimes the  skin may be sensitive to Alcohol or minoxidil itself. Before go to bed use some good cream right bellow  where the redness accrue . It should help.

Minoxidil is an irritant so it can cause itching. It will also have NO value in growing out your transplanted hair.
