How often should I wash my hair?

The last time I was at the hair cutting salon, the person who washed my hair asked me if I washed my hair everyday. I said I did, and she said she could tell. I'm not sure what she meant by this, but please tell me how she could determine this, and what is the best overall practice for washing hair in terms of frequency. I'm interested in the health of my hair as well as the health of my scalp. Thanks for you help!


Should I smoke?

Hi! Your site is very helpful. I have a few friends who smoke. We are friends since the past four years; they started smoking about a year ago. They tell me to smoke, I don't do it, so they call me a jerk. I have never TOUCHED a cigarette in my life.

Should I smoke?

If I smoke one cigarette about once a week, will it harm me in any way?

Will it make me a chain smoker?

Which is the safest brand of cigarette, health wise?


How contagious is measles and how is it spread?

A friend of mine is living with someone who might have just got measles (results pending). If true, and my friend has also got it, how contagious is it? I think it is measles, rather than German measles, which I had as a child. Does past illness provide any defense? That is, can you get it twice? I presume having had German measles does not provide any protection against measles.

How is it transmitted? Like a cold? (Physical contact, common contact with hard surfaces, and maybe airborne?)


Should I come out to my girlfriend about my boy-crush?

I am a bisexual guy, and I have a problem. I have a girlfriend and a major crush on my best male friend, each of them are straight. I have already told my friend about my sexuality and my crush on him, but I am afraid to tell my girlfriend. She is an understanding person, but I think she might think I went bi because of her. How should I tell her? I am pretty paranoid about this, and I haven't even told my parents about my sexuality. Please help me.


Is it possible to reopen a closed piercing?

I have two piercings in each earlobe; however I have not worn earrings in the second set of holes for several years. Recently I tried to insert earrings into the seldom-used pierce holes. One earring went in with no problem, but the second did not go through after several attempts (I actually gave up because my last attempt bent the earring post). I have tried inserting other earrings but they also will not go all the way through. Is this something I can fix myself? Do I have to get the same hole professionally re-pierced? Will there be problems with scar tissue at the site?


Should I get the meningitis vaccine?

1) I'm a college student and I've heard in the media that meningitis vaccine shots are recommended. How do I get more information and a shot?

2) As a parent of a college freshman this fall, I was concerned about the increasing publicity that Meningitis has received recently over the networks. Since the population most likely to be infected includes young adults living in close quarters, do you recommend vaccination and where is it available?


Is reusing water bottles safe?

I started buying bottled water because it seemed to taste better. As an experiment, I tried refilling the empty bottles with tap water and refrigerating them. And I discovered that what I really liked was drinking chilled water out of the bottle. If no one else is using the bottles, how often do I need to wash the bottles out with soap as opposed to just re-filling them?
