Tell me necessary steps to proctect my hair from removal?

If, by "removal"... ...You mean "falling out" - as in "going bald" - this depends on the cause, duration, whether you are a man or woman - lots of factors. A dermatologist can tell you exactly what is going on and make suggestions for treatment. Just don't waste your money on the various "hair vitamins" and other worthless over-the-counter products.
