Can alopecia be cured and how?

Depends: Alopecia can be a separate disease but is normally a symptom or an inherited problem and not a seperate disease. The first step to determine if it can be reversed is to determine the cause. You will need to see a doctor who deals with your problem to be evaluated.

Tel Effl.spontaneous: If you have telegen effluvium due to postpartum hair loss, lack of eating redmeat, lsck of iron, zinc, HUGE stress, and secondary to meds like antidepressants, reducing the triggers has a good chance of having it cured spontaneously.
