You need to stop coloring your hair 24/7. Dying your hair is the worst thing you can do. Your natural hair color is definitely enough.
There are different ways to make your hair thicker. I use Rosemary Oil and Coconout oil, but you have to be patient and use it for half a year, only then will you see results. Reasons for thin hair could be: drugs, alcohol, smoking, poor diet, you rub your hair with a towel vigorously and for a long time, you often use heat to dry your hair, Hormonal imbalance, vitamin deficiency, poor liver/gut health. Or you simply have thin hair because of your genetics. For a men i would say take fin and minox if you start to loose ur hair. To be honest, I don't know if women can take that jfl you look like a woman.
