My Dear
Welcome to Healthcaremagic!
I have studied your symptoms and accompanying details.
I assume from the description that you are most likely having
Female Pattern Baldness which is a condition of hair loss in the specified areas well before the ages of say 45-50 years.
Minoxidil, especially its 2% variant is a commonly prescribed medication for this condition.
However, minoxidil is effective only as long as it is regulatory used. There are few other drugs as effective as minoxidil and I would ask you to refrain from their use because of cost and safety considerations.
If you follow simple measures like proper food, exercise, and a health lifestyle, you will note the improvement in not only in hairs but even in other parameters of health including prevention of hair loss and their thickness.
I am sure this advice is going to make you enjoy healthy hairs.
Best wishes from Healthcaremagic!
