Description
A normal hair cycle includes the following stages, a growth stage (anagen), a degenerative stage (catagen), a resting stage (telogen), and a shedding stage (exogen). Hair shedding/fall occurs naturally daily, but when the shedding becomes excessive, the situation becomes concerning (1).
Topical treatments are not always effective as the problem requires an internal solution. Research suggests that many underlying factors within the body can impact the hair growth cycle. But if the root cause gets addressed then one can manage the hair thinning (2).
Several factors can influence hair health. Here are some key factors and their impact on hair:
- Nutrition: Inadequate intake of protein, vitamins, minerals, and other nutrients can lead to hair thinning, dryness, and brittle hair (2).
- Hormonal Imbalances: Hormonal changes, such as those that occur during pregnancy, menopause, or certain medical conditions, can affect the hair growth cycle. Imbalances in hormones like estrogen, testosterone, and thyroid hormones may contribute to hair loss or thinning (2).
- Stress: Chronic stress can disrupt the normal hair growth cycle, leading to excessive shedding or hair loss (2).
- Genetics: Genetic factors can influence hair texture, density, and susceptibility to conditions like pattern hair loss (androgenetic alopecia) (2).
- Environmental Factors: Exposure to pollutants, UV radiation, harsh chemicals, and extreme weather conditions can damage the hair cuticle, leading to dryness, brittleness, and breakage (2).
- Medical Conditions: Certain medical conditions, such as alopecia areata, scalp infections, autoimmune disorders, and nutritional deficiencies, can impact hair health and lead to hair loss or thinning (2).
