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.
1 You can use them either when your hair is damp or dry, but I feel like you get better results when your hair is a bit damp. After putting the product in your hair starting from the ends, twist and scrunch your hair to get nice curls.  Repair the damage from the perm! You can save your hair maybe up to 75% in my opinion.
