community How important are Retinoic and Hydrocortisone in topical serum?
The conversation is about using a topical serum for hair loss with ingredients like finasteride and minoxidil, and the option to exclude retinoic acid and hydrocortisone due to concerns about long-term effects. One user prefers using only finasteride, avoiding minoxidil and retinoic acid, and plans to remove hydrocortisone in future orders.
