Scalp Issues: Causes and Solutions for Painful Bumps - Dermatology

When it comes to scalp issues, particularly the appearance of painful bumps, there are several potential causes and solutions to consider. Based on your description of having developed 3-5 hard bumps on your scalp, which have become painful over time, it is essential to explore various factors that could be contributing to this condition.

Firstly, the bumps you are experiencing could be folliculitis, which is an inflammation of the hair follicles. This condition can be caused by bacterial or fungal infections, irritation from hair products, or even friction from hats or helmets. Given that you have recently changed your shampoo to one containing zinc pyrithione (ZPT), which is commonly used for dandruff treatment, it is possible that your scalp is reacting to this new product. Some individuals may develop sensitivity or allergic reactions to certain ingredients in hair care products, leading to inflammation and the formation of bumps.

Additionally, the frequency of washing your hair has increased from once or twice a week to three to five times a week. While maintaining scalp hygiene is important, over-washing can strip the scalp of its natural oils, potentially leading to irritation and dryness. This could exacerbate any existing conditions or sensitivities, resulting in painful bumps.

Regarding the supplements you mentioned—biotin (甲鈷胺) and ginkgo biloba (銀杏葉)—these are generally considered safe for most individuals. However, any supplement can have side effects or interact with other medications, leading to unexpected reactions. While it is less likely that these supplements are directly causing your scalp issues, it is worth considering if you have recently increased their dosage or if you are experiencing any other side effects.

To address your concerns, here are some recommendations:
1. Consult a Dermatologist: Given that the bumps have become painful and have increased in number, it is advisable to seek professional medical advice. A dermatologist can provide a thorough examination and may perform tests to determine the exact cause of the bumps.

2. Review Hair Care Products: Consider discontinuing the use of the new shampoo containing ZPT for a short period to see if your scalp improves. You may want to switch to a gentle, sulfate-free shampoo that is less likely to irritate your scalp.

3. Scalp Hygiene: While it is important to keep your scalp clean, try to find a balance in washing frequency. Washing your hair too often can lead to dryness and irritation. Aim for a frequency that keeps your scalp clean without over-drying it.

4. Avoid Irritants: Be mindful of other hair products you use, such as styling gels, sprays, or oils, as these can also contribute to scalp irritation. Look for products labeled as hypoallergenic or designed for sensitive skin.

5. Monitor Symptoms: Keep track of any changes in your scalp condition, including the size, number, and pain level of the bumps. This information will be helpful for your healthcare provider.

6. Consider Allergies: If you suspect that you may have developed an allergy to a product or ingredient, consider conducting a patch test or consulting with an allergist.

In summary, the painful bumps on your scalp could be due to a variety of factors, including changes in hair care products, increased washing frequency, or even underlying skin conditions. Consulting with a dermatologist will provide you with the best course of action to diagnose and treat your scalp issues effectively.
