Hair loss can cause us many troubles, not only affecting our life and work, but also bringing us significant mental stress. So, what are the general causes of hair loss? 1. Endocrine disorders: Hair growth is affected by various hormonal influences. The pressure from routine work, life, and studies can cause disruptions in physical functions, as well as conditions like postpartum and menopause, leading to endocrine disorders. 2. Nutritional deficiencies: Nutritional deficiencies and abnormal metabolism can lead to hair loss, with severe malnutrition even causing diffuse hair loss. 3. Genetic factors: Typically, males are more prone to hair loss due to genetic traits that manifest under the influence of androgens. 4. Physical illness: Some medications taken for diseases can cause side effects, including hair loss. 5. Physical and chemical hair loss: Frequent perming and hair dyeing, long hours in front of computers, and frequent use of mobile phones can all lead to hair loss.

What is hair loss lacking?

Hair loss is often related to deficiencies in vitamins such as vitamin A, vitamin B, and trace elements including iron, zinc, and calcium. It is also related to the lack of nutritional factors, such as a deficiency in high-quality protein, which can lead to hair loss. Hair loss can be associated with many factors, including nutrition, diet, neurological and mental factors, as well as certain diseases including endocrine disorders and immune system diseases that can cause hair loss. Therefore, when experiencing hair loss, it's important to carefully analyze the reasons, and visit a hospital to determine the specific causes. If the cause is a deficiency in trace elements and vitamins, appropriate supplements should be provided. If it is caused by diseases, timely treatment of the primary disease is necessary. In terms of diet, it is also important to consume foods rich in protein and vitamins.

How long will postpartum hair loss last?

Postpartum hair loss is a common physiological phenomenon among women after giving birth, but it is unpredictable how long the hair loss will last. For most women, postpartum hair loss can persist for six months to a year, after which hair growth gradually returns to normal. It is important to prevent hair loss after childbirth. For example, it is advisable not to wash hair too frequently; washing every three days is generally sufficient. Additionally, it is important to enhance nutrition and maintain a balanced diet, as the most important source for hair is protein. Therefore, consuming more protein-rich foods is recommended.

Can seborrheic hair loss grow back?

Seborrheic alopecia, also medically known as androgenic alopecia, is generally more common in men, with a relatively lower incidence rate in women. The occurrence of this disease is mostly related to vigorous secretion of sebaceous glands, or it can be said to have a certain relation to family genetics. The condition can be improved with standard treatment, but it may not fully recover, especially for patients with severe symptoms, such as receding hairlines or baldness, who find treatment rather challenging. Generally, standard treatment at a dermatology department of a formal hospital can restore about 80% of the original condition, which is considered quite effective. Complete recovery is generally difficult to achieve clinically. Treatment can include oral and topical medications, and can also be complemented with long-term conditioning using traditional Chinese medicine.

When does postpartum hair loss begin?

Postpartum hair loss generally begins three months after childbirth and is a normal physiological phenomenon. In medicine, it is also known as telogen effluvium postpartum. The main reason for hair loss is related to changes in estrogen levels in the body after pregnancy. During pregnancy, the increased levels of estrogen slow down the rate of hair loss and extend the life of hair. However, after giving birth, hormone levels gradually decrease and the hair loses hormonal support, leading to hair loss. This condition typically starts around three months postpartum and can gradually improve around six months after childbirth.

How to treat seborrheic hair loss?

Seborrheic alopecia, also medically known as androgenetic alopecia, is associated with excessive secretion of sebum by the sebaceous glands, consumption of spicy and stimulating foods, or frequent staying up late. Most patients have a certain genetic predisposition, with parents also displaying similar hair loss. Upon encountering this condition, it is necessary to treat it with medication. The most commonly used medications include Vitamin B6 tablets, finasteride tablets, and anti-grease hair growth tablets. These medications require long-term usage, and the treatment period is relatively long, lasting at least one to three months or more, to potentially control the condition. Topical medications can include the use of minoxidil solution. It is important to maintain a proper diet and lifestyle, strengthened exercise, avoiding spicy and stimulating foods, and persisting long-term to possibly prevent the recurrence of the condition.
