Mario Lacouture: How Do I Treat a Patient with Dermatologic Toxicities to EGFR Inhibitors?

Use tretinoin three times a week, dermaroll once a week, and apply minoxidil daily, but avoid using all three on the same day. Tretinoin is preferred over hydrocortisone and should not be used immediately after dermarolling.

The user has been using minoxidil for over a year with little success, added tretinoin cream, and is considering adding red light therapy. They are advised to use moisturizer to counteract skin sensitivity from tretinoin.

Minoxidil may cause dark circles and affect collagen, and Tretinoin might help counteract these effects. Users suggest caution with Tretinoin due to potential Vitamin A toxicity and recommend using it sparingly with sunscreen and moisturizer.

Oral minoxidil and finasteride are the main treatments for hair loss, with microneedling as an additional method. Tretinoin gel is not necessary with oral minoxidil but can be used for skincare.

Using retinol with minoxidil may not be as effective as tretinoin, but retinaldehyde or adapalene could be alternatives. A micro-roller with minoxidil is suggested for better results.

Tazarotene may be more effective than tretinoin when combined with topical minoxidil for hair loss due to its selective binding to RAR-beta and gamma, though it can cause irritation. Tazarotene's potency can lead to indirect inflammatory reactions despite potentially causing less irritation than tretinoin.
