Hair loss can be due to a variety of medical conditions. Hair loss might manifest itself as receding hairline, thinning hair, or the hair falling out in patches. Possible causes include genetics, malnutrition, hormone imbalances, stress, parasites, medical treatment, or certain hairstyles.
Genetic hair loss
Women can also lose hair, although it is slightly less common. Female pattern hair loss is also often less obvious, as the hair loss is spread out over the head. Therefore, the patient experiences a gradual thinning of the hair, especially later in life, which is less obvious than male pattern baldness.
The science of hair loss and malnutrition is not well developed. There are many nutritional products which promise to restore or promote hair growth, but few of them are scientifically proven.
All these medicines should be discussed with a doctor before taking and should only be taken on prescription. Luckily, most medical treatment-related hair loss is reversible and should cease when the drugs are no longer being taken.
For example, tight braids, cornrows or dreadlocks can eventually lead to hair falling out if the hairs are tied too tightly. A similar effect might be observed in people with long hair who have tightly pulled buns or ponytails.
