What is up with this new trend of putting food products like olive oil or avocado juice into hair? Is it more healthy than using shampoo?

I go through phases where, when I sleep, I don't have any dreams (that I remember, at least). I sleep well and I wake up rested. Every few months I go through a week or two when I have nights full of incredibly vivid dreams and I wake up remembering at least five or six of them. Because of all these vivid dreams, I wake up feeling far less rested than I do when I don’t dream at all. Is there a particular reason for this? Does dreaming more at night mean your sleep is less restful?

I have a problem. I am a 21-year-old male with the face of a 15-year-old. What I mean is that I am unable to grow facial hair. I was late starting puberty and it has left me underdeveloped. My baby face is affecting people's trust in me, especially at my job. I am constantly referred to as the kid and I feel that I am never really taken seriously. I am wondering if there are any types of drugs that can possibly aid in my facial hair growth problem and, if there are, what are the side effects? Please help me. I am sick of being a man trapped behind a child's face. Thank you in advance.

I am an incoming international student and I would like to keep doing some laser hair removal sessions. I know laser hair removal has become really a "fashion" and I would like to go somewhere safe, since I am concerned with my skin. I do not know the city, and I would like to know if there is any place that can be safe to do this.

I have been a vegetarian for two years. Since last year, I have been losing quite a bit of hair. I have no pattern of male baldness in either side of my family. I do take multi-vitamins everyday. My diet is fairly nutritious. Could there be any correlation between my vegetarianism and the hair loss? Some books point to folic acid deficiency so I have made an effort to buy vitamins with 100%-200% RDA recommended folic acid. Do you have any ideas on what might be causing this?

Lately, I've come to realize that I have a very powerful tendency to fall asleep in class. It seems that I can't stay awake in any lecture style class where I have to listen to the professor and take down notes — where there is minimal engagement on my part. I've pretty much fallen asleep in all of my lecture classes, during one part or another for the whole semester. I think I'm getting regular sleep — six hours at a minimum. I don't like to drink coffee or anything.
