Hello there. I can understand your concern. Certain hormone disorders cause hirsutism. PCOD is also one such disease which can cause. If you want to treat hirsutism, then the hormonal imbalance needs to be treated. And for that we need to find out what exactly is causing it. There is no home remedies. No relationship between flaxseed and this. Consult a endocrinologist in person for further evaluation and management.
