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!


Why is my wife losing hair?

Please give me some tips on how to make my nails grow stronger and fast.


Can you lose weight if you meet your caloric goal early in the day?

My friends and I disagree — can you settle the dispute? I feel a calorie is a calorie no matter what time of day that you eat it. They say that if you eat all of your calories early in the day, that it is less fattening, because you will be moving around burning off those calories. I say that if you eat 1800 calories a day, it doesn't matter if you eat them in five meals or ten meals, it is still 1800 calories. I believe that the idea of not eating anything after 7 p.m. helps you to lose weight because you cut out the high calorie, high fat foods that are often eaten late in the evening. They say that by not eating after 7 p.m., you lose weight because you're not moving to burn off those calories. Please settle the dispute. Thanks.


Is liposuction permanent fat removal?

My husband and I are having a debate over the value of liposuction as a means to permanent fat removal. He has read that we are born with specific number of fat cells and therefore believes liposuction has the ability to reduce the number, resulting in permanent fat loss in the areas that are surgically treated. I differ in the belief that fat loss and its permanency depends on maintaining and correcting diet that is related to metabolism. I also maintain that there is no such thing as permanent fat loss from liposuction. Have you an answer to our debate?


What are the risks of gel and shellac nail manicures?

I love getting my nails done with a gel or shellac manicure. The polish doesn't chip at all and stays shiny for weeks. I'm just worried about the UV light used to seal the manicure - it is almost like a mini tanning bed for your hands. What are the risks? And are there any bad chemicals in the polish?
