Clinical Toxicity of Retinoids

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.

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.

Topical retinol does not affect hair loss and may help hair regrowth. It is different from isotretinoin, which can cause hair loss due to its systemic effects.

Tazarotene may outperform tretinoin for hairline treatment with minoxidil, but lacks evidence. Tretinoin is recommended for the scalp, while tazarotene can be used on the face.

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.

Tretinoin can irritate seborrheic dermatitis, but using it with a moisturizer on calm skin may help. Parallel Health's skin microbiome testing and phage therapy are suggested for persistent issues.
