Mostly in animal products.
I believe the answer is c. nuts and seeds.
People are generally slaves to thinking about the past or future. The past is poorly remembered. The present is new reality moment by moment and thought is the enemy of present moment awareness. The present can’t be thought about but only experienced as it happens.
The chemicals used only last for a short time, usually about 6 months, although this varies from person to person. So colour or curl will 'fall' out after a while.
Even if the process was permanent, your hair continues to grow, so the colour or curl will not be in the hair coming out of your scalp.
The term, 'permanent' was invented because this treatment lasts a lot longer than a rinse or hair curlers.
Be more specific so I can help you
