Control ZeroTM

Safe - Long Lasting - Effective - Formaldehyde Free

The Control Zero and Cynectin Synergy


Stage 1: Straighten the Hair Safely and Efficiently

The curl pattern or characteristic shape of hair is due to the fact that different parts of the hair have different protein levels, making it a virtual patchwork of harder and softer “bridge” areas. Control Zero straightener uses an edible food grade active ingredient to open the disulfide bridge that gives the hair its characteristic shape, allowing it to be styled or straightened. Other chemicals have been used in the past to do this job, ranging from thioglycolates (which smell like cat urine) to formaldehyde (which is banned in many parts of the world because it is environmentally harmful and a known carcinogen). There are no paraben preservatives in Control Zero. We use a highly effective yogurt based enzyme instead.

Stage 2: Repair Any Damage to the Hair

No matter how the straightening is done, when the cuticles of the hair (which encase the long keratin strands) reform after straightening, the infrastructure has been weakened by the broken disulfide. Laboratory tests have shown that after a lye “relaxing” treatment, hair strength is only 20% of what it was before the treatment and after a formaldehyde treatment hair is only 75% of its pre-treatment, strength. The multi-Cynectin keratin protein blend used in Control Zero Masque -- an integral part of the Control Zero system -- has been laboratory proven to restore hair to its pre-treatment strength. In many cases, where hair has been compromised by overtreatment in the past, the hair is left "better than new".

Stage 3: Leave the Hair Better than New!




SMOOTHING IS NOT HAIR STRAIGHTENING because the underlying structure of the hair remains unchanged. SMOOTHING CHEMISTRY is a process in which positively charged molecules called "cationic surfactants" (they have an extra proton, making them positively charged) are allowed to attach themselves to the negatively charged keratins that form the hair cuticle (a high percentage of those negatively charged proteins are actually sticking out, like the spines on a cactus). Smoothing surfactants have two parts, one that loves water (hydrophilic) and another oily part that hates it (hydrophobic). The water loving part attaches to the hair, while the oily ends "stick out" and that is what gives the hair its smoothness and weight. It lasts only until it is washed out with the detergents (the surfactants in shampoo). The best keratins, like those used in Cynectin, will benefit the hair, but they will not keep it straight without breaking the disulfide bonds first.

Control Zero Masque acidity "protonates" the hair and adds more hydrogen bonds between the keratins in the hair. Other products often use oily surfactants to "glue" frizz and split ends together for a washing or two.



Rebuilding Bridges

While we know that the curliness or straightness of hair depends on the shape of the hair bulb in the skin, the stability of that shape – the reason it stays curly or straight – is caused by a chemical bond in the protein cysteine, often called the disulfide bridge. These bridges make the hair stable and the geometric shape (the helix) is angled depending upon bonds between the amino acids. These bridges make the hair stable and the curliness or straightness depends upon them.

Hair proteins are stretched when the bridges are broken and can be reshaped because the bonds that hold them together in the shafts of the hair have been broken (also called, reduced), When the breaking process ends after styling, new disulfide bridges are formed between the neighboring cysteine proteins. It is good to wait a day or two before wetting the hair by washing, because bridge building take some time. That is real straightening and not just smoothing.

How to break the bonds is the key question

The reducing agent used in so-called Brazilian keratin treatments is formaldehyde (often mislabeled in the US under a variety of names). It is very effective and doesn’t smell much, but it is an environmental hazard and has been proven to cause cancer. It is forbidden in most of the world in quantities large enough to be effective for bridge breaking. Another popular chemical are the “thios” which are used in traditional permanent waves, but which smell terrible because of the large amount of sulfur they contain and release. Control Zero's reducing agent is so safe that you could eat it safely!

According to Dr. Paul McAndrews, a Beverly Hills dermatologist and hair restoration expert (quoted in The Los Angeles Times), was asked "Why put formaldehyde in a hair-straightening product at all?" His answer: Hair is first shampooed to make it more porous so the keratin solution can bond with the hair shaft effectively. When the keratin is applied, McAndrews says, it "fills in the natural defects of the hair shaft, which makes the hair look smoother and silkier, but it does not actually straighten the hair." After the hair is blown dry, a stylist uses a flat iron to activate the formaldehyde, temporarily altering the structure of the hair. "The straightening occurs from the heating process combined with the formaldehyde, causing it to appear straighter," McAndrews says.
As beauty expert Nancy Lichtenstein reported in 2007 (in Yahoo), "While keratin is indeed an ingredient in the formulas used to perform Brazilian Hair Straightening, the true active ingredient is formaldehyde (as in embalming fluid).”
BKT/FORMALDEHYDE – THE ONLY CHOICE IS STRAIGHT, aggressive flat ironing to activate the formaldehyde tends to leave hair pin straight (with Control Zero you have much more control over the style and "softening" of the curl pattern). The high temperature needed for formaldehyde activation with BKT can actually "fry" hair keratins. Control Zero flat ironing can be at a much lower temperature.

BKT LEAVES HAIR FEELING HEAVY because silicone, waxes and other products are left in the hair and not rinsed out (with Control Zero, rinse-out is part of the process, leaving hair feeling more natural)
BKT LEAVES HAIR LOOKING SHINY because you have just flat-ironed wax and silicone onto the outer surface of the hair.
THERE HAS BEEN AT LEAST ONE DOCUMENTED death from a BKT treatment. In March 2007, a 33-year old Brazilian woman actually died from the process. Anvisa, Brazil's National Health Surveillance Agency, states that an excess of noxious fumes were released from the heat when she took a shower after leaving the solution in her hair for 4 days.
