pH measurement testifies to the good quality of a shampoo or soap.
pH is an indicator of the acidity of an environment, which is measured on a scale of 1 to 14.
A product with a pH of 7 is considered neutral, while a product with a pH below 7 is acidic and a product with a pH above 7 is alkaline.
To have healthy hair, it is important to maintain an appropriate pH. A healthy scalp has a pH between 5.4 and 5.9, and hair has a more acidic pH of 3.67. For comparison: classic soaps have a pH around 10.
Using a slightly acidic shampoo, between 4 and 6, can help maintain the natural balance. Homnès shampoos have a pH between 5.5 and 6.5.
If you have problems with dry or irritated scalp, or your hair is damaged, using a shampoo with an acidic pH can help nourish and protect it. Homnès nourishing shampoo designed for this purpose has a pH of 6.25, to gently cleanse the scalp while respecting the hair.
It is also important to consider factors that can increase the pH of the hair and damage it, such as straightening, heat, mechanical treatments and the use of alkaline solutions.
Finally, if you have dandruff, using a Homnès purifying shampoo with a pH around 5.9 will help relieve the problem.
