I find choosing among all of the available sunscreens and sunblocks to be very confusing. Of the following three products I am currently using, which one is giving my skin the most protection: sunscreen SPF 30 with UVA, UVB, and IR sun protection; sunblock SPF 17 with UVA, UVB, and IR sun protection; or, sunblock SPF 50 with UVA and UVB sun protection? By the way, what is the difference between a sunSCREEN and a sunBLOCK?

My girlfriend and I were wondering about dying her pubic hair. Is it okay to use regular hair dye or are there special products to use for it?

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?

1) I was born with thick and coarse hair. It all sticks up when it is short. I lose confidence when I notice that people always look at my hair. Is there any way I can make them softer? Will medication help?

2) I seem to have very untamable hair. I keep the hair on the side of my head really short because of this. It's not that my hair isn't uncombable or anything like that, but if the hair on my sides grow even the slightest they start sticking out at 45-90 degree angles to my head, and there is nothing I can do about (I've tried everything but STIFF STUFF....). I look at other people's hair and they don't even need to blow dry or comb it and it sticks firmly to the sides of their heads. Is there a reason why some people have such easy control over their hair? Is it something I'm eating or doing wrong? Thank you for any advice!

For a number of years I have had acne from waist down. I can't find any information on it except for acne of the face and back. I'm embarrassed to wear shorts in the summer. Any suggestions?

I have taken three Depo-Provera shots. My hair started falling out excessively several months ago. In looking for answers I found out that this is a side effect to the shots. I was not informed of that before I took the shots. I saw in one of your Go Ask Alice! answers that depo-provera suppresses the Follicle Stimulating Hormone and the Luteinizing Hormone. What is this hormone? Is this what makes my hair fall out? And do you know if there is anything I can do to stop it? My next shot is due by May 15 but I am not going to get it. Thanks.

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?

1) Over the span of the last couple of years, I have noticed a significant number of moles appearing on my body. They have been appearing everywhere from my neck to my inner thighs. I had one on my neck since childhood, but now have so many more. Is this normal? Is it something I should be concerned with? And does child bearing have any relevance to this happening?

2) I have a mole which has turned very dark purple, and grown a bit in size (still small). This is the second time it has done this — last time was a couple of weeks ago, and it slowly faded back to almost nothing until today. Should I be very concerned about this?
