Did you get your
thyroid and iron levels checked? If not, please get those done. There could be various reasons for hair thinning and hair loss leading to different types of hair losses. As you mentioned, stress could’ve triggered it and if it is genetic on either of your maternal/paternal sides, it could only worsen with age. Depending on underlying causative factor, need to manage it accordingly.
Results again depends on what kind of hair loss you are suffering with. With some, further progression of thinning is controlled and with some regrowth could be attained.
Hope this helps. Happy to answer any other concerns, if any.
