Ten Pearls Every Dermatologist Should Know About the Appropriate Use of Relaxers

A user experienced burning, itching, and soreness on their scalp after a perm in 2021, despite using oral finasteride, oral minoxidil, and ketoconazole shampoo. They are seeking advice on whether to pursue further medical tests or consult a neurologist for nerve pain.

Shampoos are unlikely to cause permanent hair loss; hair loss is more likely due to male pattern baldness (MPB). The user is advised that losing hair in the shower is normal, and to avoid shampoos with sodium sulfate.

Selenium sulfide shampoo helped with a sore scalp but may cause hair root damage. Users experienced hair loss with selenium sulfide and ketoconazole, suggesting reducing use if hair loss occurs.

A user experienced hair thinning and scalp issues after using a sebum-regulating shampoo and perm treatments. They are advised to consider potential allergies, try a simple shampoo, and research treatments like finasteride for possible male pattern baldness.

The conversation is about identifying the cause of a burning red scalp from a topical hair loss formula. Retinoic acid and ethyl alcohol are suspected irritants, with retinoic acid being considered for removal.

Mixing retinol, rosemary oil, and minoxidil on the scalp may cause burning but no significant damage is mentioned. Another user plans to use peppermint oil instead of minoxidil due to its side effects.
