The beauty of hair depends not only on fashionable haircuts and coloring, but also on the shampoo that you use most often. When choosing hair cosmetics, be sure to pay attention to pH. Why do this and what does this indicator affect?
What does shampoo pH mean?
Surely you have noticed that when choosing a shampoo recommended by friends or advertising, you are faced with the fact that it does not suit you. For example, the hair roots become oily the next day, hair dye is washed off quickly or dandruff appears. If so, then it's time to figure out what acid and alkaline shampoos are.
Normal pH
It is important to know that an indicator such as pH affects not only the hair, but also the scalp. The fact is that normal pH healthy skin - 4.5-5.5. And shampoos with this indicator are suitable only for normal and sensitive hair. Their "trick" - they allow you to normalize the acid-base balance of the hair. For example, the Natura Siberica line.
Alkaline pH
If the number exceeds the 7 mark, the pH balance of the scalp is shifted to the alkaline side. This contributes to the opening of the hair cuticle, they become porous and fluffy. Dandruff may also appear due to the growth of fungi.
Most often, the shift to the alkaline side occurs after dyeing, hair straightening and perm.
Alkaline shampoos are recommended for oily hair, in addition, they are used for the procedure detox - deep cleansing. Again, due to the fact that they contribute to the disclosure of hair cuticle scales. Hair detox is a recently popular procedure that can be performed at home (once a month). It not only cleanses the scalp, removes styling residues from the hair, but also facilitates the absorption of nutrients. Therefore, detox shampoos tend to have a pH above 7, but are not suitable for continuous use.
Acidic pH
Why do you need acid shampoo or acid shampoo? If we talk about acidic agents, then they contribute tosmoothing cuticle scales. Therefore, acidic shampoos are used after dyeing the hair, which allows you to close the color inside the hair. As a result of using "acidic" shampoos, hair looks healthy, smooth and shiny.

- Most often, acidic pH shampoos work well for those with damaged and dry hair.
- After a radical change of image. For example, the transition from dark to light is very aggressive, the pH balance becomes higher than normal.
- After unsuccessful chemical exposure.
- It is equally important to choose the right shampoo for those with curly / wavy hair.
- They will also come in handy after highlighting and staining.
- If you have dandruff. In this case, it is worth using products with an acidic acidity level - less than 7.
How to find out the specific pH of a shampoo
Unfortunately, in the Russian Federation this task is not an easy one. The point is that it is not necessary. But there are manufacturers who indicate the pH on the packaging. For example, Subtil, Bonacure line, care level 4.5.
There is a way out: purchase indicator test strips. They are sold in pharmacies and even on AliExpress. Such litmus tests are useful not only for shampoos. They are indispensable when checking the pH-level of balm, hair masks and even facial cosmetics. Output: it is advisable to know the pH level in order to correctly choose cosmetics for yourself, to maintain the color of the staining longer and not to suffer from brittle ends.
