Cradle Cap: Symptoms, Causes, Treatment & Prevention

Cradle Cap is a type of skin condition that develops in infants and is almost similar to seborrheic dermatitis seen in adults.  In its milder form Cradle Cap causes little flaking of the scalp skin especially on the vertex part. Usually the condition is considered to be harmless and its gets cured by itself over time. However, when severe it can cause thick scaling and formation of crusts that can distress the babies. In this article you can learn about the causes, symptoms that help to spot Cradle Cap, and ways to prevent Cradle Cap in infants.

What is Cradle Cap?

Cradle Cap is a skin rash characterised by scaly, yellowish patches or crusts that develops on scalp of infants. It usually develops within the first few months after birth and is common in infants aged one to three months. It is similar to seborrheic dermatitis seen in adults. However, it does not cause much itching as with adult seborrheic dermatitis. Although Cradle Cap is not a very serious condition, the thick white or yellow scales are often difficult to remove from the infants scalp. Cradle Cap mainly affects the scalp but can also occasionally spread to other body parts such as face and diaper area.

What Causes Cradle Cap?

The causes of Cradle Cap are not completely understood yet. However, experts believe that Cradle Cap could be caused due to following reasons

  1. Excess activity of sebaceous gland on scalp skin: The hormones that are passed from the mother to the baby before it is born can contribute to development of Cradle Scalp. The hormones increase the production of sebum and so cause the rash on scalp. Excess of greasy sebum production on the scalp causes old skin cells to stay adherent to the scalp instead of falling off. Presence of fatty acids also causes excess turnover of scalp cells leading to the flakes.
  2. Fungal growth: Another cause of Cradle Cap is the fungus called Malassezia which is present in the normal bacterial flora of the skin. The fungus degrades sebum to release fatty acids. The fungus consumes only the saturated fatty acids as a food source and leaves behind the unsaturated fatty acids. However, the presence of fungus is a cause of Cradle Cap only in infants who show more susceptibility to it.

Should you be Worried About Cradle Cap?

The straight answer to this is No. Cradle Cap is generally a harmless skin condition and resolves on its own. And, so there is no need for much concern about the condition. It is not a contagious skin condition; it does not spread on close contact or on sharing items such as hair brushes, hats, caps bedding, towels, or other clothing items. The condition in infants may be caused due to hormones that increase sebum production or due to yeast or fungus present in the skin. Cradle Cap is not caused due to poor hygiene. However, the scaling on the scalp cannot be washed away easily from an infant’s head. Also, constant thick scaling and formation of yellow crusts can make the baby uncomfortable.

How Common is Cradle Cap?

Cradle Cap is a common skin condition in infants and the incidence is reported to be around 10 % in   infants up to the ages of 1 month. Cradle Cap shows higher prevalence by 3 months of age affecting about 70 % of infants. The condition generally clears up by age 1 year and responds to some simple treatments. In infants aged 1 to 2 years, the prevalence is only 7%.

How to Treat Baby's Cradle Cap?

Cradle Cap usually clears over time by itself. However, since the constant scaling of scalp skin can be a cause of distress to the baby or even the caretakers, simple treatment for Cradle Cap may be recommended.

  1. Massaging with mineral oils
    Massage with baby mineral oil on the scalp helps to loosen up the scales and crusts. The oil should be left on the scalp only for 10 to 15 minutes followed by head bath using baby shampoo. After washing hair the scales can be brushed off using fingers or brush with soft bristle. The oil massage on scalp can be performed few times in a week. It is important to use only a mild and baby certified oils or shampoos for washing the scalp.

  2. Topical steroids
    If the scaling does not loosen up with oil massage or washing, simple steroid lotions can be applied to the scalp. It is necessary to use the steroidal lotion on baby’s scalp only after doctor consultation. Topical steroids also help to reduce the scalp inflammation caused in Cradle Cap.

  3. Medicated shampoos
    At times doctor may allow use of anti-dandruff shampoos. However, these can be extremely irritating to the eyes and hence needs to be used with care. Anti-fungal shampoo containing ketoconazole may be recommended in case of yeast or fungus being the cause of Cradle Cap.
