The thickness or thinness of hair strands is related to the structure of the hair follicles.
Hair strands can become weak and fall out due to factors such as underlying illnesses, medication use, improper hair
care practices, and severe stress. However, this condition is usually temporary. With proper care and appropriate
treatments, hair can easily recover.
Hair strands do not structurally thin out or become thin on their own, unless they are naturally thin or temporarily
affected by negative factors.
