Im losing my hair in very large quantity how to reduce fall?

Alopecia: Its possible that your hypothyroid and that's causing it. Iron deficiency and Lupus are several other causes besides the male pattern hereditary hair loss that everyone knows about. If the latter is the case..topical Minoxidil works well and is the safest. Several medications designed for prostate issues (finasteride & dutasteride) do slow the process but you need a doctor involved.
