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.

Can hair loss be inherited?

Hair loss generally has two common types: alopecia areata and seborrheic alopecia. Seborrheic alopecia has a certain hereditary nature, whereas alopecia areata does not have a hereditary aspect. Most cases are related to deficiencies in vitamins, trace elements, or low immunity. Seborrheic alopecia has some hereditary factors and is a genetic disease carried by males in the family. Once this disease occurs, it is not easy to completely eradicate and tends to worsen with age. Generally, one can take oral medications to reduce oil secretion, avoid spicy and stimulating foods, and avoid staying up late and stress. It is advisable to wash hair with lukewarm or cold water, and avoid using very hot water. After recovery, it is important to exercise more, consume more vegetables and fruits, and supplement vitamins and trace elements.

Can sulfur soap be used to wash hair for seborrheic alopecia?

If you are experiencing seborrheic hair loss, it is not recommended to use sulfur soap for shampooing. This is because sulfur has a degreasing effect and can treat seborrheic dermatitis, but sulfur is irritating to the scalp. Its strong degreasing effect on the scalp can alter the scalp's microecological environment, which is not conducive to the normal growth and recovery of hair. Therefore, it is not advisable to use sulfur soap for shampooing when experiencing seborrheic hair loss. With the advancement of science, many dandruff treatment and hair growth promoting skincare products can be used for shampooing. We can choose these types of products which cause less damage to the scalp barrier and are more gentle in degreasing, avoiding major irritation and facilitating the recovery of the scalp.

Is it good to wash your hair frequently if you have seborrheic hair loss?

Frequent shampooing is not good for those experiencing seborrheic hair loss. This is because frequent washing does not alleviate symptoms of seborrheic hair loss. For oily scalps, shampooing temporarily reduces oiliness, but washing too often can lead to a buildup of chemical residues, causing scalp inflammation and worsening hair loss. Frequent shampooing also damages the scalp's lipid barrier, leading to temporary dryness and scalp dermatitis, further exacerbating hair loss. Therefore, frequent shampooing is not recommended for those with seborrheic hair loss. For individuals experiencing seborrheic hair loss, it is advisable to visit a dermatologist at a reputable hospital promptly. Under the guidance of a doctor, appropriate medication and lifestyle advice can effectively cure the condition.

How to treat hair loss?

There are many types of hair loss, such as sudden localized patchy hair loss known as alopecia areata, androgenetic alopecia which is related to genetic factors and dependent on the action of androgens, also known as seborrheic alopecia, as well as postpartum hair loss due to insufficient qi and blood after childbirth, and telogen effluvium caused by rapid weight loss or dieting. The specific treatment of hair loss should be based on the corresponding cause. The cause of alopecia areata is not completely clear, and it is related to factors such as emotions, stress, endocrine disruption, and autoimmunity. Treatment generally includes oral intake of compound glycyrrhizin tablets and topical application of minoxidil. If the skin lesions are widespread or severe, the combination of corticosteroid treatment may be considered, and treatment generally lasts several months or even longer. Androgenetic alopecia often occurs between the ages of 20 and 30 and is related to familial genetics. The treatment of this condition lacks very effective remedies. Treatment options include topical minoxidil, and oral intake of finasteride. Traditional Chinese medicine has relatively good effects in treating androgenetic alopecia, including the oral intake of Chinese herbal medicine and local acupuncture treatment. Attention should be paid to avoiding staying up late and maintaining a light diet. When the hair follicles have already closed, local hair transplantation can be carried out, transferring hair from the occipital region of the scalp to the top. If the area of androgenetic alopecia is too large without sufficient follicles for transplantation, then the use of a wig should be considered. (Note: Medications should be used under the guidance of a physician.)

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.
