Premature hair loss is becoming increasingly prevalent among younger men and women today. While thinning hair is not unusual for men over the age of 30 and women over 50, early hair loss may be an indication of other health conditions. Thinning hair in younger people may also affect their confidence and become a source of stress, which in turn can exacerbate hair loss.
Research has shown that hair has a “metabolism” characteristic. An animal study published in the journal Molecules highlighted that hair contains functional metabolomes, including amino acids and lipids. By analyzing hair segments based on their growth rate, researchers can gain insights into metabolic changes occurring over time. Generally, we lose and regrow some hair daily—shedding up to 100 strands a day is considered normal.
