whoa the first thing you need to do is STOP worrying about your hair falling out because that causes more stress and its a big cycle…what you need to do is have a patients and get on a regular excersise plan..jog everyday for like 30 mins or 15 mins and strecth then go again for 15 more mins if you are out of shape…excersising releves stress sorry i cant spell.
also confront your problems head on…for example..if you have a paper due in a month..start working on it. dont stress over it for the whole month…haha im doing that…not doing my hw but answering your question instead lol anyway…seriously have a laugh breathe and if your hair loss is due to stress…you have to attack the stress at the source
also excersising make hair grow back faster because of the blood flow to your whole body will bring nutrients to the scalp. It takes a few months but it will come back. for now wear a hat!!!

There are many possible causes for this type of hair loss. The hair growth cycle is very sensitive to changes and disturbances. Even a slight disturbance can disrupt the hair growth cycle. Possibilities include extreme dieting or weight loss, illness especially with high fever, trauma, exposure to toxins, medication, birth control pill etc. The hair loss usually begins 2-3 months later.
I lost most of my hair during a two month period of time. Essential oil formulas were very effective to help me regrow my hair. They may help you also.

You should most certainly see a dermatologist first as that would ascertain the real reason behind your hair loss. Quite possibly you have been trying products aimed at treating a specific problem which you do not even have so there is no way they would help you out. Once the actual cause is known you would be in a much better position to know which treatment / product you need to use.
