Seborrheic dermatitis of the scalp

I recently noticed that my hair falls out easily when I wash it, about three to five strands each time.
The doctor said this is normal because hair is naturally shedding, and washing it just accelerates the process.
However, the lengths of the strands vary; some are quite short, and I'm worried about balding.
The doctor mentioned that my scalp is red and swollen, which is diagnosed as seborrheic dermatitis, and prescribed a medicated shampoo (which I bought for over a hundred dollars for a small bottle).
Is this not covered by health insurance? I'm just curious because I don't know.
After using it, should I return for a follow-up? Do I need to keep washing my hair with it, or is it unnecessary?
I read in foreign reports that rinsing hair with water is better than using shampoo.
I also asked my friends in beauty and hairdressing, and they advised me not to use white, lotion-like shampoos, but rather transparent ones.
Should I use transparent shampoo or just water? Is it best not to use the same brand all the time, or can I use different formulas from the same brand? Since I've experienced hair loss when washing, I listened to my friends' recommendations and used Brand X, while I previously used Brand Y.
Is it really better, or does it depend on individual constitution (I have allergies)? I wash my hair every two days, but sometimes my scalp itches or feels damp from rain.
How often should I wash my hair normally? I'm a bit anxious about premature balding.
The doctor said a few days ago that it won't happen and that I have a lot of hair, but I have a high forehead.
I read an article stating that if the hairline is more than three finger widths from the eyebrow tip, it could indicate future balding.
Mine is dangerously four finger widths wide, and I'm worried (no one in my family is bald).
Sorry for the lengthy message, and thank you for your help!

Hello: There are several types of shampoos for seborrheic dermatitis, and it depends on the specific ingredients; most of them are not covered by health insurance.
If hair loss is caused by seborrheic dermatitis, you may consider using shampoos that contain ingredients such as coal tar or zinc pyrithione.
Typically, washing your hair two to three times a week is sufficient.
Additionally, you can use medicated shampoos containing ketoconazole to reduce the quantity of Malassezia yeast on the scalp.
When shampooing, apply a sufficient amount of shampoo to your hair and lather it up, gently massaging the scalp with your fingertips.
Do not rinse it off too soon; allow the shampoo to remain on the scalp for 5 to 10 minutes before rinsing thoroughly with water below 40°C to avoid excessive irritation to the scalp.
Thank you!

More Info

Seborrheic dermatitis is a common skin condition that can significantly affect the scalp and lead to symptoms such as redness, itching, and flaking. It is often associated with hair loss, which can be distressing, especially for young adults. Understanding this condition and how to manage it effectively is crucial for maintaining both scalp health and hair density.

Understanding Seborrheic Dermatitis
Seborrheic dermatitis is characterized by an overproduction of oil and the presence of a yeast called Malassezia on the skin. This condition can lead to inflammation, which manifests as red, scaly patches on the scalp and other oily areas of the body, such as the face and chest. The inflammation can disrupt the hair growth cycle, leading to hair shedding. While it is normal to lose some hair daily (about 50 to 100 strands), excessive shedding can be alarming, especially when it appears to be linked to scalp irritation.

Hair Loss and Scalp Care
1. Consultation with a Dermatologist: If you notice increased hair loss or scalp irritation, it is essential to consult a dermatologist. They can provide a proper diagnosis and recommend appropriate treatments. In your case, the diagnosis of seborrheic dermatitis is significant, as it can be managed effectively with the right approach.

2. Medicated Shampoos: Your doctor may prescribe or recommend medicated shampoos containing active ingredients like ketoconazole, zinc pyrithione, selenium sulfide, or coal tar. These ingredients help reduce inflammation, control the yeast overgrowth, and alleviate itching. It is essential to follow your dermatologist's instructions on how often to use these shampoos, as overuse can sometimes lead to further irritation.

3. Washing Frequency: The frequency of washing your hair can vary based on individual needs. For seborrheic dermatitis, washing your hair every 1-3 days with a medicated shampoo is often recommended. If you experience increased oiliness or itching, you may need to wash more frequently. However, if your scalp is dry or irritated, less frequent washing may be beneficial.

4. Choosing the Right Shampoo: While some people prefer clear shampoos over creamy ones, the effectiveness of a shampoo depends more on its active ingredients than its appearance. It is essential to choose a shampoo that suits your scalp condition. If you have sensitive skin or are prone to allergies, opt for gentle, hypoallergenic formulations. Switching between different brands or types of shampoos can sometimes help, but it’s best to consult with your dermatologist before making changes.

5. Lifestyle Factors: Stress, sleep quality, and diet can all impact the severity of seborrheic dermatitis. Managing stress through relaxation techniques, ensuring adequate sleep, and maintaining a balanced diet can contribute to overall skin health. If you have a history of allergies or sensitivities, be mindful of the products you use on your scalp and skin.

6. Monitoring Symptoms: Keep track of your symptoms and any changes you notice. If your condition worsens or does not improve with treatment, follow up with your dermatologist. They may need to adjust your treatment plan or explore other underlying causes of your symptoms.

Conclusion
Seborrheic dermatitis can be a challenging condition, particularly when it leads to hair loss. However, with proper diagnosis and treatment, it is manageable. Regular consultations with a dermatologist, adherence to prescribed treatments, and attention to lifestyle factors can help you maintain a healthy scalp and minimize hair loss. Remember, it’s essential to be patient, as improvements may take time. If you have concerns about your hair loss or scalp health, do not hesitate to seek professional advice.
