Opinions Please!

63 yo F. Ok…here’s my story. Two years ago my hair started thinning after an illness and post menopause. I began using minoxidil topical 5% one time a day (at bedtime). Within a few months I stopped shedding so much and began getting baby hairs in areas - not all areas of thinning tho. I have kept using minoxidil since. In March, I started tirzepatide and I must say, I love it! However, I have been shedding atrociously and my hair has really thinned considerably. I will be starting GHK-cu/KPV next week and am wondering can I stop using the minoxidil if and when I see improvements in my hair? I also use topical AHK on my scalp in the mornings. All thoughts will be appreciated!
