Hair started thinning around 45 - thrilled with results but requires maintenance

Thanks to genetics and perimenopause, my hair started thinning around 45 and got progressively worse with wide parts and patchiness that I had to hide. Around 49, I became interested enough in PRP to purchase a package. I had three consecutive treatments and have been following up with maintenance treatments twice a year for the last two or three years. While my hair isn't quite as robust as it was when I was getting monthly treatments, it is still FAR better than it was when I was in my mid to late forties. When I go in for treatments, I often have to tell them were to inject because my hair grows so consistently so I definitely think it is well worth it.
