Solid conditioner and shampoo bars (syndet) are becoming very popular in upscale soap boutiques with a hefty price tag. They are great to use when traveling and easy to store. Many shampoo bar formulas have a high ph, however, we have developed one using mild surfactants for a ph between 6 and 7. This is a completely hands-on workshop. No sodium hydroxide is used in this class.
Participants will also learn how to test the PH in the shampoo bars and what it means to have a good range.
We ask participants to be on time to respect all other attendees
We welcome teens from 15 years of age onwards.
Option available for unscented or scented with essential oils or fragrances.
According to the US National Institutes of Health, alkaline pH may increase the negative electrical charge of the hair fiber surface and, therefore, increase friction between the fibers. This may lead to cuticle damage and fiber breakage. It is a reality and not a myth that lower pH of shampoos may cause less frizzing for generating less negative static electricity on the fiber surface. Interestingly, only 38% of the popular brand shampoos against 75% of the salons' shampoos presented a pH ≤ 5.0. Pediatric shampoos had the pH of 7.0 because of the “no-tear” concept. There is no standardized value for the final pH. The authors believe that it is important to reveal the pH value on the shampoo label, but studies are needed to establish the best pH range for both the scalp and the hair fiber's health.
