Your baby's hair growing upwards could be due to a few reasons, the most common being uncombable hair syndrome (UHS).
Uncombable Hair Syndrome (UHS)
Uncombable Hair Syndrome, also known as spun-glass hair, is a genetic condition that affects the structure of the hair shaft. This structural abnormality prevents the hair from lying flat, causing it to stick out in multiple directions, often upwards.
Key Characteristics of UHS:
- Appearance: Hair is typically dry, frizzy, and has a silvery-blond or straw-colored appearance.
- Direction: Hair grows outwards from the scalp in different directions, making it difficult to comb flat.
- Texture: The hair shaft may have triangular or heart-shaped cross-sections, contributing to its unmanageability.
- Onset: UHS usually becomes noticeable between infancy and early childhood, often around 3 months to 12 years of age.
- Improvement: In many cases, UHS improves or resolves spontaneously as the child grows older.
Causes of UHS:
UHS is usually caused by mutations in one of three genes:
- PADI3: This gene provides instructions for making an enzyme involved in hair shaft formation.
- TGM3: This gene also provides instructions for making an enzyme involved in hair shaft formation.
- TCHH: This gene provides instructions for making a protein that helps give hair its shape.
Diagnosis and Management:
-
Diagnosis: A doctor can diagnose UHS based on the appearance of the hair and sometimes by examining a hair sample under a microscope.
-
Management: There is no cure for UHS, but gentle hair care practices can help improve the appearance and manageability of the hair. These include:
- Using a soft brush
- Avoiding harsh shampoos and styling products
- Conditioning the hair regularly
- Gently detangling the hair
- Avoiding excessive heat styling
Other Possible Reasons
While UHS is the most likely cause, other factors can contribute to hair growing upwards:
- Natural Hair Texture: Some babies naturally have hair that is more prone to sticking up, especially if it is fine or curly.
- Hair Growth Cycle: The angle at which hair emerges from the scalp can vary, potentially causing some hairs to point upwards.
- Static Electricity: Dry air can cause static electricity, making hair stand on end.
When to Consult a Doctor
While usually harmless, consult a doctor if you are concerned about your baby's hair growth, especially if:
- The hair is extremely brittle or breaks easily.
- There are other unusual symptoms, such as skin abnormalities.
- You have a family history of hair disorders.
