Acne , spots, grey hair. Be cured ever?

I have acne and started getting grey hair since I got my periods i.e since I was 13 years old. My periods are very regular. I am under medication. As soon as I stop the medicines My acne starts to appear again. Even my hair started thinnning. Hairfall is very normal. I rarely eat junk food or spicy food. My diet consists of homemade food, fruits etc. My doctor suggested to get a sonography done because he suspects I have Pcos. But I doubt because my weight is very normal and periods are regular and I cant see any symptoms of pcos except the acne. Till now I have took seratin, follihair, azithral, isopil, minonil er 65 and many more medicines. Few months ago when I stopped to take my medicines i started getting acne again and it was very severe. This condition is genetic as my mom and her family had the same skin problems. I am suffering since more than 7 years. I have tried homeopathy and ayurvedic as well. Cant this be cured ever?
