# Does the health of the hair affect the processing time or temperature of heat needed? Is this process safe to use on damaged hair?

## Checking the hair prior to full application with a STRIKE4 test-strand is the best way to determine if STRIKE4 will maintain the integrity of the hair.

As with all color services, if the hair is compromised, a test strand must be taken to ensure  
superior color results. The beauty of framesi STRIKE4 is that the test strand can be done in 20  
seconds. The test strand will determine if the hair is able to take another color service, what flat  
iron temperature the hair needs, and how many passes are sufficient. Proceed with caution if  
hair is compromised…
