Scalp itching associated with seborrheic hair loss can arise from two possible scenarios. One is that the itching is due to seborrheic dermatitis accompanying the hair loss. The other possibility is that the scalp, being greasy, provides a conducive environment for the proliferation of microbes, leading to a fungal infection of the scalp, which then results in itching and increased dandruff. In cases of seborrheic dermatitis, the affected area may show erythema and papules with oily scales or crusts, and there may even be exudation, crusting, and erosion, resembling eczema. The local treatment should primarily focus on degreasing, anti-inflammation, and itch relief. When fungal infection is also present, antifungal treatment becomes the priority. Ketoconazole shampoo can be used in such cases, applied three times a week for a period of 6-8 weeks.

Hair loss is divided into several types.

There are many types of hair loss, mainly including androgenic alopecia, neurogenic alopecia, endocrine alopecia, nutritional alopecia, and physical alopecia. Androgenic alopecia is clinically known as seborrheic alopecia, while neurogenic alopecia is also called alopecia areata. Therefore, if you notice a significant amount of hair loss, it is essential to promptly identify the cause. In addition to the types of hair loss mentioned above, there may also be chemical-induced hair loss, infectious hair loss, symptomatic hair loss, congenital hair loss, seasonal hair loss, and other types.

Is supplementing with zinc useful for seborrheic hair loss?

Patients with seborrheic alopecia can appropriately supplement with zinc-rich preparations and foods, which have certain auxiliary effects on the hair. Seborrheic alopecia, also known as androgenic alopecia, is a type of hair loss characterized by genetic factors and dependent on androgen action. It can occur in both men and women, though it is more common in men. Treatment mainly targets the hair follicles, and there is no particularly effective cure. Treatments can include topical application of 2% or 5% minoxidil solution, oral administration of finasteride, and for women, oral spironolactone can be used. If necessary, treatment can be supplemented with traditional Chinese medicine and scalp acupuncture, including plum blossom needle therapy. For cases of seborrheic alopecia where the hair follicles have significantly atrophied, scalp transplantation and hair transplantation may also be options. Patients with seborrheic alopecia should also pay attention to their diet by consuming light, nutritious foods and avoiding spicy and irritating substances. It is beneficial to consume foods containing high-quality complex proteins and various vitamins, including vitamins, trace elements, zinc, copper, calcium, etc., all of which assist in hair growth.

Difference between seborrheic dermatitis and seborrheic hair loss

Seborrheic dermatitis, also known as seborrheic eczema, is a chronic inflammatory skin disease that occurs in areas with excessive sebum secretion, such as the face, chest, and back. Seborrheic dermatitis is not the same as seborrheic hair loss, although some patients with seborrheic dermatitis may also experience hair loss. Generally, seborrheic dermatitis starts on the face and then spreads downwards to other areas, accompanied by varying degrees of itching, and is commonly seen in adults and newborns. Seborrheic dermatitis is associated with factors such as psychological stress, dietary habits, deficiencies in B vitamins, alcohol consumption, and sleep deprivation. As it often starts or is primarily localized on the scalp, symptoms can worsen and spread to other areas. The disease tends to occur in areas that are oily, hairy, and sweaty. As the sebaceous glands open into the hair follicles, the initial skin lesions of seborrheic dermatitis are usually small, red papules around the hair follicles. As the condition progresses, these papules can develop into red patches. Some patients may also have oily scales or crusts, as well as varying degrees of hair loss.

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.
