Hello, I understand your concern. There is a number of reasons why hair falls out more than usual. First of all it should be noted that it is normal for people to lose up to 50 strands of hair per day. If you have noticed that your hair has been falling out more than usual, it could be down to many reasons, the most common of all being stress. Stress could also explain your memory problems. Sorting out your life, putting things into perspective and adopting a more relaxed life style would solve this problem. If, however, you do not think your stress levels are high enough to justify this, then you should look to your diet. Is it healthy? Are you eating the right foods for you body? Usually, taking vitamin supplements, or a multivitamin will solve this kind of issue. If you think your diet is fine, then you should see a doctor in order to get a check up and do the appropriate tests to find out the potential culprit. I hope this helps. Wishing you all the best.
