Bubble hair deformity is damage of the hair shaft, resulting in patches of short weak brittle hair, that feels rough.[1]

It is typically caused by chemicals and heat; temperatures greater than 125 °C on wet hair, such as with the use of hair dryers, hair straighteners and curling tongs.[2]

Definition

Bubble hair deformity is damage of the hair shaft, resulting in patches of short weak brittle hair, that feels rough.[1]

Cause

It is typically caused by chemicals and heat; temperatures greater than 125 °C on wet hair, such as with the use of hair dryers, hair straighteners and curling tongs.[2]

Mechanism

Bubble hair is characterized by rows of bubbles seen microscopically within localized areas of the brittle hair.[3] These air-filled spaces occur in the cortex of the hair shaft that correspond to the breakdown of keratin and local air expansion triggered by hot water passing through the shaft.[2] There may be an inherited predisposition.[4] It can be associated with trichorrhexis nodosa and trichoptilosis.[2]

Diagnosis

Diagnosis can be confirmed by microscopy.[3]

Prevention

Avoiding excessive heat and chemicals can prevent the condition.[2]

Epidemiology

Bubble hair is more common in females.[2]
