The answer is Topographical Model. Sigmund Freud’s Theory has
complexities though his writings, it was one of his overall theory of
personality out of five parts. Freud
studied that most of what we experience in our lives, the underlying emotions,
beliefs, feelings, and impulses are not available to us at a conscious level. He
also understand that different driving forces develop during these stages which
play a significant role in how we interact with the world.
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.
Bipolar disorder and depression are Mood Disorders.
This means that they are both mental health conditions that affect your mood in a chronic way, it is more than just being sad or happy. Depression is chronic (meaning long lasting), persistent, debilitating sadness/misery/despair. It creates extreme low mood. Bipolar disorder is a mixture of depression and mania. Depression would be the low mood and mania would be the exact opposite which is extreme high mood and happiness which leads to irrational and sometimes destructive behavior.
