Retinoids: New Uses and New Synthetic Agents

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.

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.

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.

Pyrilutamide's effect on sebum production and scalp inflammation is unclear, with users noting no significant changes. Isotretinoin is mentioned as effective for reducing sebum, while Dutasteride and various shampoos have limited impact on oiliness and seborrheic dermatitis.
