Zada shampoo: Is a homemade technique for lightening wires safe?

What is shampoo?

 

The shampooing , also called cap soap, in English, is a technique created with the intention of removing synthetic dye from strands (whether it is a toner or a toner). Generally, you use a mixture of hydrogen peroxide, bleaching powder, and shampoo to lighten the hair.

 

Due to the promise of changing the tone of the locks in a simple and fast way, the method has spread widely on the Internet. However, professionals such as hairdressers and trichologists do not consider shampooing safe and advise against doing it at home.

 

How is shampoo made?

 

The hair is washed with shampoo in the same way as bleaching, but with a mixture of hydrogen peroxide, one sachet (40 g) of bleaching powder and a tablespoon of shampoo. According to the most popular recipes, the method is usually used as hydrogen peroxide volume 10 or volume 20 .

 

“Hydrogen peroxide with volume 10 does not have lightening power, it is only intended for deposition of pigment, that is, coloring. To lighten the color, we use more than 20 volumes,” highlights hairstylist Patti Cherry, who specializes in hair coloring. wires.

 

In practice, the result of Zada ​​shampoo leads to less lightening than the mixture used in professional beauty salons for hair bleaching. But, according to Patty Sherry, this happens because Zada ​​shampoo uses ineffective product selection .

 

“Bleaching powder was not developed in order for the surfactants in the shampoo to react, causing a loss of hair pigmentation effect, making the proposal to remove the dye ineffective,” the professional explains.

On the Internet it is believed that due to shampooing with hydrogen peroxide up to 20 vol., it will be less harmful to the hair than discoloration. However, according to Patti Sherry, this is not true.

 

Bleaching literally “malnourishes” the locks and removes the dye for lighter shades. For this purpose, professionals use hydrogen peroxide over 10 volumes and bleaching powder.

 

“Many think that using hydrogen peroxide at a volume of 20 will be less aggressive than a 40. However, what really changes is time. The damage is the same,” says the hairstylist.

 

Thus, Zada ​​shampoo interferes with the health of wires in the same way as discoloration. The difference is that, in shampoo, the presence of the shampoo will prevent the bleaching action . “By diluting the bleaching powder with shampoo, we lose time and money. The bleaching process will be much slower and less effective,” explains Patti.

 

When the wires are fragile, it is not recommended to shampoo and change the color. “Whoever allows or does not allow a procedure is the hair, so a strand test is essential. If that hair can no longer receive any chemical, there is a great way to risk chemical cutting, ” ponders Pat.

 

The dangers of shampooing hair

 

Trichologist Ademir Leite Júnior warns that in shampooing there may be an incompatibility between shampoo, hydrogen peroxide and bleaching powder when mixing. “The three products, when found in the same bottle, can generate harmful chemical reactions for the scalp ,” he says.

 

According to the specialist, there is also a greater risk of damage to the wires due to the fact that there are two steps (bleaching and wire cleaning) performed in one. Thus, neither the bleaching nor the cleaning promoted by the shampoo will work safely and efficiently.

 

The doctor also tells that shampooing is not a method recognized and promoted by the cosmetics and professional hair coloring industry – which may pose more risks for those who decide to do this method at home.

 

It is also worth noting that shampooing has the same contraindications as bleaching. That is, people with severe diseases or injuries of the scalp should not do it. The same is true for pregnant women and anyone with sensitive, weak, thinning, or chemically saturated hair.
