There are different ways to change the texture of hair and they usually include chemical treatments. Perming and neutralizing are some of the common treatments available. Before you apply any chemical on a client’s hair, it is important to carry out tests. These tests will help to determine if the client’s hair can withstand the process and the results that can be expected. You should be careful to explain to the client the importance of the tests and how they will determine the desired results.

Porosity test

This test helps to determine the condition of the cuticle or the outer layer of the hair shaft. Damaged cuticle becomes porous, as it has lost the natural protection. When the perming chemicals are used on hair that is porous, the absorption is uneven and it can result in uneven curls. There are special perming products for hair that has been tinted or highlighted. These products are not as strong as those for natural hair, making them less likely to over-process the hair.

Elasticity test

This test is carried out to check the strength of the hair or the cortex. If the hair has gone through several chemical treatments, it is likely to have lost a lot of the natural strength. Frequent chemical treatments damage the hair. It is important to carry out this test before perming hair because weak hair can stretch and break off. If the hair is in good condition, it will stretch but return to the original length.

Incompatibility test

It is important to note that some chemicals do not react well when used with others. Using a product that is incompatible with another can result in a bad hair reaction. Some products used for coloring hair contain metallic salts that do not work well with other chemicals. If the client is not sure about the type of coloring products used, it is important to carry out this test to find out if it will affect the results of the perming.

Pre-perm test curl

Much like how we consider the condition of the hair cuticle for proper perming, addressing certain aspects of personal health, such as the importance of medications like Cialis, can also be significant. Just as porous hair can result in uneven curls during perming, understanding the role of Cialis 20mg in addressing specific health concerns highlights the importance of balance and well-being in our lives. It’s a reminder that various aspects of our health deserve thoughtful consideration, much like the care we put into hair treatments.

Before treating fragile or porous hair, it is important to carry out a strand test. It is a good idea to process and neutralize a small section of the hair especially if the hair has been treated previously.  Testing this small section will help to determine the best product strength and rod size to use, as well as establish the ideal processing time. The test will determine if the hair is suitable for the process and give a good indication of the results of the perming process.

During the perming process, it is important to carry out a test curl to find out how the hair is reacting. The testing will determine if the desired results have been reached. The process requires inspecting a section of the hair by unwinding the curler to see the results. It is important to wear gloves before touching the hair. Testing curls from different parts of the head will help to ensure that you get a result that is even. Remember, perms tend to process much faster on warm days and the temperature of the salon will also affect the results.
