Causes of hair loss are:
Age related baldness: female pattern hair loss (thinning of hair throughout the scalp) occurs in upto 10% of females. It can occur at a young age in some persons, specially those with a familial predisposition.
Stress: any cause of stress , like a major surgery, personal problems, etc. can cause hair loss which occurs about a month to three months after the event.
PCOD: this can cause hair loss due to high testosterone levels
Disease: the three most common diseases that cause this are diabetes, thyroid disorders and Lupus.
Nutrition; poor diets not rich enough in protein or iron.
Medications: drugs used for gout, depression, blood thinners, anti-hypertensives, birth control pills, chemotherapy.
High fever or other illness: hair may thin out after about three months of a severe illness due to stress.
Hormonal changes: this can occur after pregnancy or with the use of birth control pills. Can also be related to menopause.
You need to do investigations like blood sugar and thyroid levels. Testosterone levels need to be checked, this is very important for you since you are known to have PCOD. If high testosterone is found you need to get back on anti androgen pills. If other causes are eliminated, then it is likely that you are having female pattern baldness.
The treatments that you can do is:
Iron supplements: you should take an iron supplement available OTC at pharmacies.
High proten diet
Minoxidil (Rogaine) : apply twice daily to the scalp. This is available OTC. Minoxidil is not be used if you are trying for pregnancy, since it can be toxic to the fetus, otherwise it is very safe. It comes in two strengths for females, 2% and 5%. It can cause some dryness and itching of the scalp initially. Hence you should start with the 2% initially and once you are used to it, use the 5%. Use it regularly for 9 months to 1 year. Results should be visible by 3 months. It is available OTC.
If this does not help, you should consult a dermatologist or a hair specialist. Other procedures like hair powder, Scalp micropigmentation and hair transplant can help you.
Take care - wish you good health and a quick recovery. Stay safe.
