What to put on low porous hair to equalize the porosity during a coloring service?
When dealing with low porous hair during a coloring service, it is important to use a porosity equalizer or a pre-color treatment. These products help to temporarily raise the cuticle layer of the hair, allowing the color to penetrate more effectively.
An example of a product that can be used is a pre-color treatment that contains acidic ingredients, such as citric acid or vinegar. These acids can help to slightly open the cuticle layer, making it easier for the color to penetrate.
It is important to note that these products should be used in moderation and according to the manufacturer's instructions, as excessive use can damage the hair.
