Hair loss (alopecia)

Definition: The phenomenon of hair loss is normal and natural. On average, we lose up to 150 hairs per day. However, this phenomenon can be considered abnormal if the loss exceeds more than 150 hairs.
Internal and external causes: Genetic factors, the action of dihydrotestosterone or androgens, hormonal status, iron deficiencies in the diet, diseases (poor functioning of the thyroid gland, hyperandrogenism, certain cancers, syndrome), medical treatments (certain contraceptive pills, androgen-based drugs, anabolic steroids, certain treatments for epilepsy, hypertension or cholesterol problems).
How to reduce or eliminate: Supplementing one's diet with dietary supplements (such as iron, etc...) in case of deficiency; prescription of a treatment (minoxidil, finasteride); consulting a health professional.
Preventative steps to take: Maintaining a balanced diet to prevent mineral deficiencies; reducing or quitting smoking; avoiding stress; refraining from using a hairdryer at high temperatures; avoiding overly harsh shampoos; reducing the use of hair dyes, relaxers, and perms; avoiding the use of overly tight hair clips or bands, and not always placing them in the same spot.
