Scalp itching?


Hello: I have never had a problem with an itchy scalp until recently.
Last month, I moved into an old, humid house, and the drainage pipes from my neighbor's bathroom run through my walls and ceiling.
They seem to be in disrepair and emit a very foul odor.
Ever since I moved in, my scalp has started to itch, but it only happens when I spend a long time indoors.
When I go outside or visit someone else's house, my scalp doesn't itch.
Could there be bacteria in the air? Is my scalp sick? Sometimes my face also feels a bit itchy.
Should I see a dermatologist? Thank you!

Kao: A damp house can indeed lead to an increase in mold and bacteria in the air, which is harmful to the skin and scalp.
It is recommended to ventilate and dehumidify the house first.
If the problem persists, please consult a dermatologist.

More Info


It sounds like you're experiencing some discomfort that may be linked to your living environment, particularly since you've noticed that your scalp itchiness began after moving into a damp, older house with unpleasant odors. This situation raises several important considerations regarding the potential impact of your living conditions on your health, particularly your skin and scalp.

Firstly, it's essential to understand that environmental factors can significantly affect skin health. In your case, the dampness and potential mold growth in an older building can lead to various skin issues, including scalp irritation. Mold spores and other allergens can thrive in humid conditions, and exposure to these irritants can cause allergic reactions or exacerbate existing skin conditions. If your scalp itchiness is accompanied by redness, flaking, or any unusual changes in your scalp or hair, it may indicate a dermatological issue that requires professional attention.

Moreover, the unpleasant odors you mentioned, which may stem from plumbing issues, can also contribute to an unhealthy living environment. Foul smells often indicate the presence of bacteria or mold, which can lead to respiratory issues or skin irritations. If the air quality in your home is compromised, it could indeed lead to symptoms like scalp itchiness, especially if you have a sensitivity to mold or other allergens.

You mentioned that your scalp does not itch when you are outside or in other people's homes, which further suggests that the issue may be environmental rather than a direct skin condition. This pattern indicates that your living space may be a significant factor in your discomfort.
Given these considerations, it would be wise to take a few steps:
1. Consult a Dermatologist: Since your symptoms are persistent and have a clear onset related to your living environment, seeing a dermatologist would be a good first step. They can assess your scalp condition and determine whether you have a specific skin issue, such as seborrheic dermatitis, eczema, or a fungal infection.

2. Improve Air Quality: Consider improving the air quality in your home. This could involve using a dehumidifier to reduce moisture levels, ensuring proper ventilation, and possibly using air purifiers to filter out allergens and irritants.

3. Inspect for Mold: If you suspect mold is present, it may be beneficial to have a professional inspection. Mold can cause various health issues, and addressing it promptly can help alleviate your symptoms.

4. Maintain Hygiene: Regularly washing your hair and scalp with a gentle, hypoallergenic shampoo can help remove any irritants. Avoiding harsh chemicals and fragrances in hair products may also reduce irritation.

5. Monitor Symptoms: Keep track of when your symptoms worsen and any other accompanying signs, such as changes in your skin or hair. This information can be helpful for your healthcare provider.

In conclusion, while your living environment may be contributing to your scalp itchiness, it's essential to seek professional advice to rule out any underlying skin conditions and to address the environmental factors at play. Taking these steps can help you find relief and improve your overall well-being.
