Hello Mr. Chen,
Thank you for reaching out regarding your mother's scalp blisters. Scalp blisters can be caused by a variety of factors, and understanding the underlying cause is crucial for effective treatment. Based on your description, it seems that the blisters may be related to chemical burns from hair treatments, such as perming or straightening, especially if the hair was subjected to heat or harsh chemicals for an extended period.

Causes of Scalp Blisters:
1. Chemical Burns: Hair treatments often involve the use of strong chemicals that can irritate the scalp, leading to blisters. This is particularly common with products that contain ammonium thioglycolate or sodium hydroxide.

2. Heat Burns: If the hair styling tools (like curling irons or straighteners) come into direct contact with the scalp, they can cause burns, resulting in blisters.

3. Allergic Reactions: Some individuals may have allergic reactions to hair products, which can manifest as blisters or rashes on the scalp.

4. Infections: Conditions like herpes simplex virus can also cause blisters on the scalp, although this is less common.

5. Dermatological Conditions: Skin conditions such as eczema or psoriasis can lead to blistering on the scalp.

Treatment Options:
1. Immediate Care: If the blisters are a result of burns, it is essential to cool the area immediately with cold water or a cold compress. Avoid popping the blisters, as this can lead to infection.

2. Topical Treatments: Over-the-counter hydrocortisone cream can help reduce inflammation and itching. If the blisters are painful, a topical anesthetic may provide relief.

3. Antibiotic Ointments: If there is any sign of infection (such as increased redness, warmth, or pus), applying an antibiotic ointment may be necessary.

4. Oral Medications: In cases of severe pain or inflammation, your mother may benefit from oral pain relievers such as ibuprofen or acetaminophen.

5. Avoidance of Irritants: It is crucial to avoid further exposure to the chemicals or heat that caused the blisters. This may mean temporarily avoiding hair treatments until the scalp heals.

6. Consultation with a Dermatologist: If the blisters persist or worsen, it is advisable to consult a dermatologist. They can provide a more accurate diagnosis and may prescribe stronger medications or treatments, such as corticosteroids or other topical therapies.

Home Remedies:
- Aloe Vera: Applying aloe vera gel can soothe the skin and promote healing.

- Oatmeal Baths: If the scalp is itchy, an oatmeal bath can help alleviate discomfort.

- Avoid Tight Hairstyles: Keeping hair loose can prevent further irritation to the scalp.

In conclusion, while scalp blisters can be distressing, understanding their cause is the first step toward effective treatment. If your mother's condition does not improve with home care or over-the-counter treatments, please seek professional medical advice. A dermatologist can provide tailored recommendations based on her specific situation.

Best wishes for your mother's recovery, and I hope she finds relief soon.

Sincerely,
