The pH scale ranges from 1 to Acidic substances have a pH lower than 7. You must be logged in to post a comment. But first, What is pH? However, t he pH of the scalp is more alkaline than the hair strands, sitting around 5.
Products with an alkaline pH increase the negative electrical charge of the hair and cause friction between the fibres. In the shower, hair with an alkaline pH absorbs water right down to the cuticles, hydrating the fibres and breaking the down keratin molecules. This causes hair to loose its shape and curl, and also causes breakage. Ideally the pH of hair products should be less than 5.
Wait for a minute as it changes colors until it gets to the final measurement. If your shampoo is of a creamier consistency, you might need to apply a coating of the shampoo to the strip and wait a few extra minutes as it measures the pH. You probably remember learning about pH in school.
Maybe you even remember doing a few experiments on it. Knowing how pH comes into play can help you better understand the needs of your hair and what you can do to help it.
So if your shampoo says its pH level, then great! But if not, take matters into your own hands and test it for yourself. We are not looking to solicit fake reviews. Many companies choose to collect five star reviews from those who have never even used their products. We are not one of those companies. Limit 1 promotion per household.

Permanent hair colors — Permanent colors that use an oxidative process usually contain a pH range from 9. Shampoo — All shampoo pH values ranged from 3. Straighteners — Straighteners are very high in alkalinity, with their position on the pH scale anywhere from Acid Permanent Solution — Acid perms, gentler on the hair, contains a value of approximately 6.
When the hair is at its peak of health, the pH ranges on the slightly acid side between 4. The disruption eventually causes the cuticles to lift, promoting frizz issues, breakage, and overall substandard hair health.
This also includes knowing the pH level of the products you use on clients. When doing chemical services such as bleaching and coloring, you leave the cuticle scales exposed and in an alkaline state. A cosmetologist should contain the knowledge of the products that assist in closing the cuticles, bringing the hair back to an acid state.
Understanding chemistry, including pH talk, is vital for a cosmetologist. It is just as important to know how the right pH in a product or service improves the hair as it is to know how the wrong pH damages the hair. The first step in getting familiar with the world of pH is knowing the correct terminology.
Alkaline solution — an alkaline solution contains a pH above 7. Alkalis bases — the hydroxides of a compound that neutralizes acids to form salts. Logarithm — the pH scale is logarithmic, meaning each tik mark on the scale is a tenfold increase in alkalinity or acidity.
