What Are the Causes of Severe Hair Loss at Age 18?

Possible causes of severe hair loss at the age of 18 may include the following: 1. **Hormonal Imbalance**: Staying up late, irregular lifestyle habits, and high academic stress can lead to hormonal imbalances, which may disrupt the hair growth cycle and result in hair loss. 2. **Malnutrition**: A lack of essential vitamins and minerals can deprive hair follicles of necessary nutrients, leading to hair loss. 3. **Genetic Factors**: If parents experience hair loss, their children may inherit the genetic predisposition for hair loss, particularly androgenetic alopecia. 4. **Psychological Stress**: Prolonged mental stress or excessive anxiety can trigger a physical stress response in the body, affecting the normal function of hair follicles. 5. **Scalp Conditions**: Scalp diseases such as seborrheic dermatitis and folliculitis can exacerbate hair loss. To effectively address hair loss, it is recommended to maintain healthy lifestyle habits and seek timely medical consultation for professional treatment.
