Hi everyone I just did a keratin treatment, so the hairdresser washed my hair, applied the product using a brush, then waited for 40 mnts, then WASHED IT OUT with water and then dried it with the blow drier and then hair straightner. I'm afraid that the treatment would not work because he washed out the product before applying any heat to my hair. Unfortunately I didn't pay attention to the brand of keratin but it does not contain formalin it is the type that smoothens the hair without straightening it.. anyone has any idea whether the treatment might work or my hairdresser did it wrong??
