El champú ¿es de naturaleza básica o acida? ¿Como puedes saberlo?

Is the shampoo basic or acidic in nature? How can you know?

The shampoo by nature is of basic pH.

Explanation:

Since the basic shampoo weakens the hair by breaking the disulfide bonds of the keratin of the hair, it is sought to slightly acidify adding small flakes of various materials, for example, glycol distearate.  

The shampoos hardly have the pH indicated, the most common is to see shampoo with balanced or neutral pH (pH 7). To know the pH of the shampoo you can buy pH measuring strips. A pH between 5.5 and 7 is correct.
