Accutane, or isotretinoin, is commonly known for reducing oil production in the skin, which is why it is effective for treating acne. However, experiencing oily hair while on Accutane is unusual, as the medication typically decreases oil production in the sebaceous glands of both the skin and scalp. Here are a few considerations that might explain this experience: Hormonal Changes: Accutane can sometimes influence hormonal balance, which might lead to unexpected changes in oil production in some individuals. Product Residue: Ensure that hair care products, such as shampoos and conditioners, are thoroughly rinsed out, as residue can sometimes make hair appear greasy. Scalp Adjustment: Your scalp might be adjusting to the changes in oil production, which could temporarily result in increased oiliness as it finds a new balance. Diet and Lifestyle: Changes in diet or lifestyle while on Accutane can also impact oil production. Consider if there have been any recent changes in these areas. Medication Interaction: If you are taking other medications or supplements, they might interact with Accutane in a way that affects oil production. If the oily hair is bothersome or persists, it would be advisable to discuss this with your dermatologist. They can provide tailored advice or consider adjustments to your treatment plan if necessary.
