- Can stem cell factor be combined with other topical hair loss solutions? No published human trial has tested topical stem cell factor alongside minoxidil or other established treatments, so neither the safety nor the benefit of the combination has been established. Community users report layering these products, but that is anecdote rather than clinical evidence.
- Is it safe to combine caffeine with other topical treatments? Only one small trial has tested caffeine together with another hair-loss topical (minoxidil 2.5%), and it favoured the combination; caffeine with topical finasteride, ketoconazole or plant oils has never been studied, so no source can call those combinations safe.
