Keratin hair treatment is becoming increasingly popular due to its ability to smooth even the curliest and most damaged hair, giving it long-lasting shine and smoothness. If you’re a hair master, it’s important to get the treatment right to give your client the best results. Before proceeding to the procedure, it is important to consider not only the type of hair, but also to conduct a thorough diagnosis of the condition of the client’s hair. Further on the results of the diagnosis to select the right compositions and proceed to the procedure of keratin equalization.

Diagnosis of hair before starting keratin treatment

Before selecting for the client composition for the procedure, it is necessary to clarify the history of hair, what procedures he performed, whether there were coloring, lightening, than, how long ago. After that, it is necessary to conduct a diagnosis of the hair, in order to correctly select the composition and deep cleansing shampoo.

• Hair thickness

The key point when choosing a keratin straightening procedure is the thickness of the hair. Thick hair, which contains a large amount of sulfur, requires more intensive treatment. For them, it is recommended to use keratin with a higher concentration of active components, which will provide a longer effect and a high degree of straightening. In the case of medium and fine hair, the choice of composition and methodology of the procedure may differ.

• Hair elasticity

One of the methods of hair diagnostics is the hair elasticity test. The elasticity of hair is important to determine its condition and ability to withstand the effects of chemical compounds. The test involves stretching wet hair and assessing its ability to return to its original shape without damage.

• Hair porosity

It is also important to assess the porosity of the hair, which can be low, medium or high. Low porosity is characterized by a dense, scaly layer of hair, making it less amenable to chemical attack. Medium porosity usually corresponds to healthy hair, while high porosity indicates damage to the hair structure. The porosity test is performed on dry hair by twisting the strands and assessing their condition.

Selection of shampoo before Keratin Smoothing procedure

Before undergoing a keratin smoothing treatment, it is essential to choose the right shampoo to deep cleanse your hair. Technical shampoo, or deep-cleaning shampoo, plays a key role in preparing the hair for the procedure. It has a high level of alkalinity, which allows you to open the cuticular layer of the hair and ensure deep penetration of the active components of the keratin composition. When choosing a shampoo, it is necessary to take into account not only the type of hair, but also the degree of damage.

Recommendations for choosing a deep cleansing shampoo:

• For stiff, ethnic, dense hair, take a deep-cleaning shampoo with a pH of 8-9. If the hair is as thick as possible, you can even leave the shampoo in for a few minutes after application.
• For medium-thick hair, use pH 6.5-8.0.
• For maximally damaged hair, use a shampoo with a pH of 5.5-6.5.
