Question: 1 / 400

What is the primary effect of malnutrition on hair?

Increased shine and volume

Hair thickening

Hair thinning or hair loss

Malnutrition significantly impacts the health of hair, chiefly leading to hair thinning or hair loss. This occurs because hair is a non-essential tissue, and during periods of nutritional deficiency, the body prioritizes vital organs and functions over hair growth. Essential nutrients such as proteins, vitamins, and minerals are crucial for maintaining the structure and vitality of hair. When these nutrients are lacking, hair follicles may enter a state of rest, which can lead to reduced hair production and eventual shedding. Prolonged malnutrition can result in more severe hair loss, as the body struggles to sustain healthy hair growth. The other options, which suggest improvements in shine, volume, thickness, or elasticity, contradict the effects of malnutrition, emphasizing the negative consequences of inadequate nutrition on hair health.
