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.

What natural food or herb can help soothe stomach ulcers?

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 just found out that a friend requires a kidney transplant. I've heard that we are all equipped with two kidneys and can live with just one. How do I find out if I can donate a kidney? What's involved in a kidney donation? Thanks!

In a recent question about abnormal hair-growth, the writer mentioned a long history of hydrocortisone use as a means of treating eczema. I too have a long history of severely uncomfortable and troubling eczema. During the worst outbreaks, I have visited several different dermatologists, and all have prescribed topical hydrocortisones, such as Hytone or Topicort, as well as anti-itching pills, such as Atarax. One prescribed Diprolene ointment, which I used for a year, until my next dermatologist dismissively told me it was far too strong and could be damaging.

I would like to know once and for all how damaging the extensive and long-term use of any of these creams is. Please give me one of your straightforward answers; I have been frustrated by the differing views and lack of concern among the dermatologists I have visited. I am tired of being told it is "just eczema." I already use the gentlest cleansing products available, tons of moisturizing cream, rinse all my clothes twice, wear soft fabrics, etc. I am still absolutely tortured by itching, often resorting to scratching at my skin with a hairbrush. The eczema reappears without fail in the same places, even on my face, and is particularly bad after stress periods, when I absolutely cannot control my itching or scratching. Isn't there anyone anywhere doing research on this? Is there anything else I can try? I am not averse to vitamin, holistic, or homeopathic therapies, if there are any. Please help. This is really a very ugly and upsetting problem.

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?

I was wondering what I personally can do (habits, diets, activities) to strengthen my immune system? Thank you!

Is it dangerous to wax or use a chemical depliatory such as Nair on areas of the skin that have moles? I've seen warnings on some labels regarding this. What could happen to the moles?

1) I read the information on your website about knuckle cracking, and I was wondering if it applies to cracking backs and necks. I know that people often have their backs cracked by friends, etc. because it feels good and seems to relieve tension. Also, when my neck feels tight, I often turn it from side to side until it cracks and feels better. I've heard that chiropractors do some version of this, and call it "realignment." Is this safe? Is there a right or a wrong way to crack a back or neck? Is cracking your back/neck actually therapeutic in some way?

2) As a college student, I sometimes spend long hours reading books or looking at computer screens, and often my neck gets stiff. Like many of my joints that get stiff, sometimes I crack my neck, like I would crack my knees or fingers when they feel stiff. I often wind up doing this several times a day.

My question is, could I do irreparable damage to my spinal system if I continue using this method to soothe a stiff neck? Could I wind up a paraplegic if I continue to crack my neck? Leak spinal fluid, etc.?

I am curious as to whether the nail bed regenerates or not. I used to bite my nails, and slowly I've bitten off some of the nail bed as well, on all ten fingers. It has been two years, and the nail bed does not seem to grow back, and my nails grow according to the new shape of the nail bed. It makes my hands look somewhat ugly, to be honest.

Any suggestions would be appreciated.
