Default opening the cuticle

this may or may not be helpful.. as it may already have been posted previously.

as someone who recently stopped smoking in an effort to pass a hair test in the coming months.. i'm doing research like everyone. i'd like to thank those of you on this forum that have taken the time to share information - both personal as well as gathered.


from http://www.vitamintrader.com/article...haircolor.html

Quote:
"To be an effective permanent color, one must open the cuticle and allow the permanent color through to the inner part of the hair. The only way to do this is to temporarily raise the pH of the hair. The resulting color will be seen through the transparent cuticle and, if the hair is properly cared for, should last until it grows out.

Raising the pH of the hair:

* pH is a measure of acidity and alkalinity
* It ranges from 0 (highly acidic) to 14 (highly alkaline)
* 7 is neutral – pure water
* The ideal balanced pH level for our hair is between 4.5 and 5.5 and is known as its isometric point.
* Above 5.5, the hair cuticle starts to open, and below 4.5, it starts to contract.
* For a permanent hair color to work, we need to open the hair cuticle by raising the pH of the hair above its isometric point.
* After coloring, to maintain condition of the hair, we need to close the hair cuticle by lowering the pH of the hair back down to its isometric point.

There are 2 ways to open the cuticle:

* The first is to suspend the hair in a harsh and highly alkaline substance like ammonia. This quickly raises the pH of the hair well beyond it’s normal value to about 11 or higher and causes it to swell considerably. It is effective for coloring purposes, but has many side effects including damage to the hair, and difficulty in returning it to its ideal pH level.
* The second and more natural method, as used by Tints of Nature, is to suspend the hair in a substance called Ethanolamine which is derived from Coconut and acts as a gentle pH adjuster and moisturizer. It softens the cuticle and, because it only raises the pH of the hair to about 9.5, causes it to open slowly rather than to rapidly swell up. Once coloring is completed the cuticle can be closed down again and the hair returned to its normal pH level by using the shampoo and conditioner supplied with the color. No damage is done to the hair."
i will continue adding info and thoughts to this as i gather/consider more info.

Does anyone know the PH level of vinegar?

While it is a acid, the PH may be high enough to open the cuticle, at least somewhat. That would go a long way towards a scientific explanation of why the Mac treatment works(at least some of the time).

according to http://www.phmeters.com/basic_ph_tutorial.htm

Quote:
Substances such as lemon juice and vinegar are acidic with pH values of 2 to 3
that info seems contradictory to the whole process..

It's listed someplace in this forum. My understanding from the reading when I first came to the site was that vinegar opened the cuticle and the C&C with the salicylic acid did the trick. Somewhat the same way taking aspirin screws up the piss test.

The first hit in a google search shows vinegar has a PH level of 2.4-3.4

Default Who knows......

I found this on hairstyle(dot)com in the home hair care tips:

Quote:
HOMEMADE HAIR RINSES
Protect your hair with a hair rinse. These hair rinses correct the hair's pH and remove residue from shampoo and other hair products, leaving the hair healthy and shiny.

Why Vinegar? Vinegar removes build-up and residue from the hair shaft and closes the cuticles. Vinegar restore natural pH and prevents an itchy scalp. Although plain white vinegar works fine, apple cider vinegar seems to be the preferred vinegar. As your hair is drying you will smell vinegar but once your hair dries there will be no smell.
So, who knows what it does in the Mac method. I don't know why, but will keep recommending the MacCujo/Zydot combo until something better comes along and I will refer real heavy smokers to Jerry G for bleach/dye instructions.

My guess is that the acid simply dissolves some hair, especially when combined with the salicylic acid in Clean and Clear. I think you're more or less creating pores, fissures and cracks in the hair, and letting the amphiphilic compounds in C+C and Tide (meaning they're designed to bond with oily substances and make them water soluble), work into the inner shaft, making the THC water soluble and letting it be rinsed out into your tub.

MacCujo seems a little bit like voodoo, and this acid=contraction vs. basic=opening of the hair shaft info is slightly contradictory, but I think that the point is that the vinegar is not "opening" the hair so much as it is helping to destroy it. That's one nasty combo to have on your hair for 30 minutes.

I believe that although it has indeed shown success, nobody can firmly say MacCujo works to any certain extent without some volunteer at-home science tests by forum members. Of course, I know that nobody around here actually guarantees results, but I'm just saying that would be the only way to prove how much more effective it is than sobriety. I'll run the T-tests

I offer myself as a control patient: 90-95 days stone sobriety.

Think I'm going to pass with a 1.5" haircut? Can I get it cut to 1.25" without anyone being upset? Will that help?

It has been tested by MacCujo and several others. Read the Results Thread.

Default acid vs. base...... or both?

Interesting information you've dug up about opening the cuticle. As I have thick hair and have been a fairly regular smoker (except for the last 33 days), I think I've heard enough to make me want to slightly modify my approach for my upcoming test

I'm thinking about a morning treatment consisting of standard macujo (vinegar, C&C, tide in the mornings) and an evening treatment of a baking soda paste rub 'n soak followed by a deep cleansing shampoo (Paul Mithcell 3 cos I can't find deep cleansing aloe rid). Did my first 'evening treatment just a short while ago. Shit, even the baking soda paste burns like hell. I figure something useful must be happening up there (fingers crossed).

No pain no gain, right?
