I need information about the chemistry behind hair perms!

The stylist winds your hair on the perm rods.  Then they add a solution of ammonium thioglycolate which breaks some bonds in the hair.  Then they wash that out and add another solution which rebonds the hair but due to the position of the hair on the rods some bind in other places which causes the hair to keep the curly shape given by the rods.\n\n(Think about what happens when you button your shirt wrong, one side gets a curve)

LoL!!!\nWow...that sounds terrifying. This can be solves easily without spending a ton of money.\nSince you mentioned your hair is so thick, you SHOULD go your local salon and have them use "thinning shears" to thin your hair out some. They'll know how to do it right. I wouldn't recommend trying this at home. Second, a serum (as mentioned above) will help work out that frizziness! Such as John Frieda Frizz Ease, or Miracle Shine (Im partial to Miracle Shine) These can be found at any department store like Wal-Mart.\nShampoo AND Conditioner - a good one to try is Got2B "Control Freak" Helps with anti-frizz. Also can be found at places like Wal-Mart.\nYou could also get a CERAMIC flat iron. These work great for me! I LOOOVE my flat iron! I got one made by Revlon that's ceramic and heats up in about 2 minutes. (About $20, but works really nice) Make sure before using it that you use a serum to protect against heat damage!\nAlso: a tip to try...When blow drying your hair, try finishing for a couple minutes on thge "cool" setting!

Try doing a Google search under the Hall or the Hall-Heroult process.    That or check out a General or an Inorganic Chemistry book from the library.  That's a good launch point.

They use hair folicals because it is most accurate at pin pointing when you used. Anything that claims to "cleanse" your hair folicals is scam.\nIt will show up!

A preparation from seaweed.\nFor reliable advice look here:\n\n**ADDITIONAL**\nI need to add a reply to the comment by elfriliminator (below) and supply additional references. 'Hair analysis' and 'geopathic stress' are quackery. Nonsensible pseudo-science. There are no medical/scientific references to these dubious claims because they do not exist.

hair rebonding gives a really straight and sleek alternative to curly heads, but it's damaging to the hair. So you need to weigh the pros and cons before going ahead.

I love my natural texture. I wear my hair in locs, and the only regret I have about it is that I didn't do it sooner. Yes, I have good hair, just like all of us unless we perm it, thereby damaging it.

Coloring and permed hair don't go together.  Hairdressers in salons want your money so they will say its fine to do.  I am a hairdresser and take it from me, whether your black or white the two don't mix well.  There's nothing you can do right now except keep it trimmed.  The healthier hair is closer to the roots.  Use conditioner.    In the future decide which is more important, colored hair or permed and do 1 .

I have been coloring the roots of my hair ( black) my natural hair color, since I was 27.  I am now 49.  About three years ago I started noticing that my hair coloring was burning my head as soon as my colorist put it to my roots.  I just did it anyway.  We are sooo vain.  It finally caught up with me this past year.  I began to develope a serious allergy to the hair color products.  I would have to be on Benedryl for about 10 days round the clock after getting my hair done.  I had it done every 5 weeks as it grew fast, and when your hair is Black, white hair is noticable.  My colorist did not want to do my hair anylonger.  She was fearful of me going into shock while in her shop...so, I had to come up with something different.  I now do my own hair, it was really scarey the first time as I had never done it myself.  Also, I researched online and found some more natural products to use.  I am happy to say that this last month when I did my hair, I only had to take 2 Benedryls as opposed to 1 every 4 hours for 10 days!  Hair dye is very toxic to our scalps and hair follicles.  Even knowing this, I still have to color my hair.  After years of doing so, the toxicity caught up to me. I Found a Natural healthier permanent coloring - brand name- NATURATINT- level 3N.  They make several different levels for semi-permanent, wash out and the one I use for permanent and 100% grey coverage.  Works great!  Cost a little bit more, but worth it for me not to die from the buring and itching and breaking out on the scalp.  Try it.  It is amonnia free.  You might have to find it in a Natural Foods, or holistic shop, maybe a Whole foods ?

I found an article which details how skin, hair and nails are renewed.\n\nI have selected some excerpts, but you might want to read through the\n\nentire article:\n\n"Encarta Encyclopedia Article"\n\nhttp://encarta.msn.com/encnet/refpages/RefArticle.aspx?refid=761569048\n\n\n\n"The skin is made up of two layers, the epidermis and the dermis. The\n\nepidermis, the upper or outer layer of the skin, is a tough,\n\nwaterproof, protective layer. The dermis, or inner layer, is thicker\n\nthan the epidermis and gives the skin its strength and elasticity."\n\n\n\nThe article says that the Epidermis is made up of mostly\n\nkeratinocytes. The youngest cells would be at the bottom and the\n\noldest at the top.\n\n\n\n"The old keratinocytes at the surface of the skin constantly slough\n\noff. Meanwhile, cells in the lower layers of the epidermis divide\n\ncontinually, producing new keratinocytes to replace those that have\n\nsloughed off. As keratinocytes push up through the layers of the\n\nepidermis, they age and, in the process, produce keratin. By the time\n\nthe cells reach the uppermost layer of the epidermis, they are dead\n\nand completely filled with the tough protein."\n\n\n\nApparently a healthy epidermus is replaced every month! You can read\n\nabout the other layer of the skin in the article.\n\n\n\nHair: "Hair is composed primarily of keratin. The protein is packed\n\ninto dead keratinocytes, much like those found in the upper layers of\n\nthe epidermis. The dead keratinocytes fuse together to form the hair.\n\nThe portion of the hair above the skin is known as the shaft, while\n\nthat below the surface of the skin is known as the root."\n\nAgain, the article has much more detail about this process.\n\n\n\nFor nails, they are also made up of "hard, keratin-filled epidermal\n\ncells."\n\n"Nails grow as epidermal cells below the nail root and transform into\n\nhard nail cells that accumulate at the base of the nail, pushing the\n\nrest of the nail forward."

As always, to understand things that humans have in their anatomies but that\nhave no apparent use [e.g., arm pit hairs] one needs to think about\nevolutionary forebears and look to closely related species for clues. Two\nlevels to the response: the nature of those particular hairs and how they\nserve to help advertize your basic adult [post-pubertal] human condition,\nhowever masked by contemporary perfumes & deodorants. Hair is akin to fur\nbut without the insulative properties, and comes in generally coarse & fine\nvarieties. The particular coarse hairs which develop in the pubic area and\nin the armpits arise at puberty [clue #1]. Hair follicles in these areas\nhave a type of sweat gland associated with them, called an apocrine gland,\nthat begins to function at puberty and is widely associated with\nscent-communication via chemicals known as pheromones [clue #2]. Apocrine\nglands produce an otherwise non-offensive secretion that now appears to be\nhomologous with animal sex-specific scents. Unfortunately its components are\nbroken down by bacteria to form odors associated with dirty locker room\nsmells. The arm pit hairs serve as extended surface from which these\nvolitile chemicals can be more efficiently broadcast. Scientific data\nsupporting the presence & effect of human pheromones have become more\nsubstantial in the last couple of years. Interestingly, perfume companies\nhave recently begun playing up the nature of human pheromones!\n\nDr. Dinsmore

Try this website.  This woman, yes I did say woman, knows her stuff.  You'll definitely need to do some reading, because as she points out, most hair products are anything but natural.  And even the ones that claim to be hypoallergenic may still cause a problem for someone who has had your experiences with dyes.  Best of luck.
