How Often Can You Use Semi-Permanaent Hair Color?

Every 6 to 12 shampoos

According to Hair Styles Cut, semi-permanent hair color "washes out in 6 to 12 shampoos, contains no potentially damaging peroxide or ammonia, and, once its gone, leaves your hair the same color as it was before being colored." Semi-permanent hair color "is safe for weekly use as there are no harmful ingredients which affect the natural melanin present in the hair fiber" as the website Hair Dressing states.

Only as needed

The Food and Drug Administration states semi-permanent hair color uses petroleum to attach onto the hair shaft, which is responsible for leaving behind color. Using semi-permanent hair color less frequently has been linked to fewer reactions of irritated skin, burning and hair loss.

Bottom Line

Semi-permanent hair color is approved for use as frequent as desired, and as needed. Although the dye can cause damaging reactions, using the hair color every six to 12 shampoos with caution can be applied without damaging the hair and the included conditioning treatments may actually leave hair in better condition than before being dyed.
