Is this improved or I am lossing again ? 2 years of fin oral 1mg and min topical

I’ve been taking oral finasteride 1 mg daily and using 5% topical minoxidil (with 0.1% topical finasteride) for about 2 years. I initially had some regrowth, but over the last 6 months my hairline has started thinning again and gaps have appeared. Overall my hairline is similar to when I started treatment. Has anyone experienced this? Would adding low-dose dutasteride or oral minoxidil be a better next step and I don’t want side effects also
