Mom wants hair permed

Been planning to have my hair permed. Everytime I go to the salon (hubby's haircut), I always make it to the point to ask the hair cutter/stylish about their prices. As always, I hear too much bucks to spend.

So I have decided to try it myself but when I read these rules, I think I will back out. About.com has a very comprehensive explanation and here are those :

• Who should get them? Perms work best on hair that has not been colored. The chemicals are too harsh for double-processed or heavily highlighted hair. Not sure if your hair is a good candidate for a perm? Ask your stylist. You’ll want to tell him or her every chemical process your hair has been through in the last couple years. One way you can find out if your hair is damaged and can't withstand more chemical processing is to do the old float trick. Take a few strands of hair and put them in a glass of water, if they sink, this means your hair is damaged and is soaking up moisture. If the strands float, this means your hair is healthy. You may want to keep it that way and avoid the perm....Oh and one other tip: The thicker your hair, the better the perm will take.
• How long does a perm take? One to two hours, depending on how long your hair is and how fast your stylist is. Your stylist will apply a single chemical solution to break the structural bonds in your hair, and another called a ‘neutralizer.’ Also keep in mind, a perm takes 28 hours to settle. Give it some time before you get too worried about the end result.
• How long does a perm last? Generally about two to six months.
• Where do I find a great stylist? First call ahead to your salon (or try several salons) and ask if they have someone who specializes in perms. Since perms aren't as popular as they were in their heyday (the 80s) you'll want someone who knows what she (or he's) doing. You may have to call around a bit to find a specialist. Even in New York City, most salons I've consulted don't have a perm specialist.
• Don’t leave home without your picture. You need to take a picture or pictures with you of the type of wave you want. Just telling your stylist what kind of curl leaves you in jeopardy of getting super-dooper tight ringlets. Stylists can control the amount of wave they give you as well as the the part of the hair they want to perm. Yours will need to choose the right-sized rods.
• A sit down consultation beforehand is a must. So many stylists will whisk you off to wet your hair without sitting down face-to-face for a good talk. Tell your stylist not only what you want (show the pictures) but what you don't want (i.e. the crimp-like curls of the 80s).
• The tightness of the curl depends on the size of the rod. If you re worried you’ll end up with too-tight curls, ask your stylist to show you the types of rods she is using. Keep in mind that tightness of curls can vary on the size of the rod and how long the solution stays in.
• Some hair is trickier to curl than others. If you are African- or Asian-American, then you will want someone who specializes in curling your type of hair.
• You can prep your hair. To prepare your hair for a perm, you'll want to use a moisturizing conditioner after you shampoo. Avoid deep-conditioning your hair for at least 24 hours before the perm, otherwise the perm may not take.
