Topical medications are only absorbed in small amounts by the body as skin is a barrier. Therefore, a topical formula is less likely to cause side effects or an increase in non-scalp hairs.
Oral medications are easier to use and do not cause scalp irritation. While they may yield better results, there is the potential for increased side effects as they are more readily absorbed by your body. It is important to note that not everyone can take oral medication for hair loss. Your Software practitioner will work with you and assess your medical history to determine a safe and appropriate course of treatment.
