Treatment of Severe Cradle Cap
For severe cradle cap, a combination approach using medicated shampoos containing antifungal agents such as ketoconazole 2% is the most effective treatment, applied 2-3 times weekly until improvement is seen.
Understanding Cradle Cap
Cradle cap (infantile seborrheic dermatitis) is a common, benign, self-limiting condition characterized by:
- Greasy, yellowish scales and crusts on the scalp 1
- Possible mild erythema underneath the scales 1
- Colonization with Malassezia fungi and sometimes Staphylococcus aureus 1
First-Line Treatment Options
Medicated Shampoos
Ketoconazole 2% shampoo: Apply twice weekly for 2-4 weeks, then reduce to once weekly for maintenance 2
Selenium sulfide 1% shampoo: Apply 2-3 times weekly
- Effective in reducing spore transmission and scaling 3
Zinc pyrithione 1% shampoo: Apply at least twice weekly
- Effective against Malassezia, though slightly less effective than ketoconazole (67% vs 73% improvement) 4
Application Technique
- Apply the medicated shampoo to the affected area
- Allow to remain on scalp for 5-10 minutes before rinsing 5
- Gently brush or comb the softened scales after washing 1
For More Resistant Cases
Oil Application Before Shampooing
- Apply mineral oil or olive oil to the scalp
- Leave on for 15-30 minutes to soften thick crusts
- Follow with medicated shampoo 1
Non-Steroidal Topical Products
- Gel creams containing combinations of:
- Piroctone olamine (antifungal)
- Biosaccharide gum-2 (antifungal)
- Zinc compounds (antiseborrheic)
- Can significantly reduce erythema and desquamation within 15-30 days 1
For Severe, Resistant Cases
Topical Corticosteroids (Short-Term Use Only)
- Fluocinolone acetonide 0.01% shampoo: Approved for seborrheic dermatitis 6
- Clobetasol propionate 0.05% shampoo:
Treatment Algorithm
- Initial approach: Ketoconazole 2% shampoo twice weekly for 2-4 weeks 2
- If thick crusts present: Pre-treat with oil application before shampooing
- If inadequate response after 2 weeks: Consider adding a non-steroidal gel cream containing antifungal and anti-inflammatory ingredients 1
- For severe, resistant cases: Short-term use of topical corticosteroid shampoo (limit to 2-4 weeks) 5
- Maintenance therapy: Once improved, reduce ketoconazole shampoo to once weekly to prevent recurrence 2
Important Considerations
- Cradle cap is generally self-limiting but can be distressing for parents 1
- Avoid prolonged use of topical corticosteroids on the infant scalp due to potential for systemic absorption
- Regular gentle brushing of the scalp can help prevent buildup of scales 1
- Treatment should continue until clinical and mycological clearance is achieved 3
