@mariemarieis right about the botox injections. Tons of people, especially women have seen success with it. The red light therapy works too but from what I understand, the results aren't as good but still decent. I think most people notice 30% regrowth.
YES! I was looking into these options myself. My husband's co-worker has a wife that got Botox injections done for her scalp. She had lost hair after having covid-19 and it never came back. So she found a clinic last year that offers it. Within 6 months her hair had filled back in. I saw the pictures!
I had work on my belly after my second child was born. I had gained a lot of weight with her and had loose skin. I don't think it was called a tummy tuck but I essentially had one. My recovery took about 5 weeks in total but I didn't feel "good" until maybe week 8 which my doctor said was normal.
