Down the side of the audiogram, there is a measure of loudness. At the top of the graph are the very. quiet sounds, going down to moderate, and then very loud sounds. The points (red circles and blue. crosses) marked on the graph represent the quietest sound which can be just heard.
Steps. 1  1. Wait at least 3 days to wash newly permed hair, or your perm would not last as long. 2  2. Use hair care products that are safe for permed hair 3  . 3. Wash your hair gently (don't scrub too hard or your hair will tangle up)(your hair is very porous and fragile). 4  4. Gently rinse your hair.
don't ever dye your hair right after perming you must wait two weeks after or dye it two weeks before, you must remember perming and colouring hair are the two most damaging tâ¦hings to do to your hair especially if it isn't done correctly, so you must give your hair time to adjust to its new state before doing it any more damage. hope this helps.
