Seeking advice on increasing volume. Had transplant 5 years back for front hairline. On 1 mg fin

Hi community,

I had a hair transplant 5 years ago and was on dutasteride for 6 months. Amazing results. Theb stopped for a year and have been on 1 mg fin and topical monoxidil. Decent progress. But my hair volume is not increasing.

Any suggestions on how to increase hair volune? Thinking if going for another transplant
