At the beginning of the year, I had a scaly growth on my scalp. I went to a skin cancer clinic to get it checked out, and it was confirmed as a seborrheic keratosis. It was suggested to me by the doctor that it was best to leave it alone, or alternatively I could get electrocautery with the risk of a permanent bald spot.

I was unsatisfied with those options so I did some Googling. The solution I found was diclofenac gel.

It's an NSAID sold as a topical solution for muscle pains, arthritis, etc. The product I used is sold as "Voltaren Pain Relief Gel 12 Hourly" in Australia, which is 23.2mg/g diclofenac gel (or 2.32%). It's generally suggested to use a strength between 1% and 3% for seborrheic keratosis.

I applied it every morning for about 6 weeks and it started to flake off after a few weeks, leaving brand new skin underneath. Completely gone. I'm pretty thrilled because I was told to live with it for the rest of my life. It cost me literally $12 to get rid of it. I hope it helps you too.
