Which of the following factors can influence hair growth?

1. Climate change

2. Genetics, health, and nutrition

3. Use of hair products

4. Hair styling techniques

The correct answer is: Genetics, health, and nutrition

The influence of genetics, health, and nutrition on hair growth is well-documented and significant. Genetics plays a crucial role in determining the hair growth cycle, density, texture, and overall hair health of an individual. Certain genetic predispositions can affect conditions like androgenetic alopecia (pattern hair loss), which is common among both men and women. Health is equally important; underlying medical conditions such as hormonal imbalances, skin disorders, or chronic illnesses can negatively impact hair growth. Hormones, particularly androgens, can either promote or inhibit hair growth depending on an individual's health status and hormonal profile. Nutrition is another essential factor, as hair follicles require a variety of nutrients to function optimally. Proteins, vitamins (such as biotin and vitamin D), and minerals (like iron and zinc) are critical for hair strength and growth. A well-balanced diet that supports overall health directly correlates with the condition and growth rate of hair. In contrast, while climate change, the use of hair products, and hair styling techniques can have some effect on the appearance and condition of hair, they do not fundamentally alter the biological processes that govern hair growth in the same way that genetics, health, and nutrition do. Thus, the interplay of these three factors
