The Scalpsense Root Activator Shampoo is effective for men with mild to moderate thinning as it cleanses the scalp and delivers essential nutrients like Mint, Rosemary, and Biotin to stimulate hair follicles. However, it may not be sufficient for severe hair loss where follicles are already inactive (such as in bald patches). In such cases, combining the shampoo with other treatments like minoxidil or hair transplants may be necessary.
