Keloid Formation and Skin Complications in Patients Treated With Isotretinoin and Undergoing Skin-Related Procedures

The conversation discusses using isotretinoin (Accutane) to reduce scalp oiliness and manage scalp issues like seborrheic dermatitis, inflammation, and chronic itch. A user shares that taking 20mg of Accutane every other day effectively reduces oily hair and skin.

The user experienced hair shedding and follicle shrinkage when using retinoic acid, despite trying different concentrations and frequencies. The hair loss persisted for six months but regrew after stopping the treatment.

The user is using a topical routine of finasteride and minoxidil, noticing increased hair growth, and is considering adding tretinoin for skin issues. Tretinoin may enhance minoxidil's effectiveness, but care should be taken to allow proper absorption to avoid unintended facial hair growth.

OP injured their temple using derma rolling and tretinoin, causing peeling and potential hair follicle damage. Users suggest the injury might be permanent, possibly resulting in scar tissue where hair won't grow.

Isotretinoin and tretinoin are different; isotretinoin can cause hair loss and has more side effects. Tretinoin may affect minoxidil absorption, and users suggest waiting before applying minoxidil.

Isotretinoin may cause hair loss by increasing DHT through a precursor androgen, DHEAS. Treatments like topical antiandrogens (RU58841, pyrilutamide) and drugs increasing PPAR-y expression (pioglitazone) might prevent this hair loss.
