This drug is more effective than minoxidil and no effect on testosterone levels in the body.

Hair transplants performed by lifting a small bunch of hair from areas where hair is still growing and placing it in the bald areas. This can cause scarring in the donor area with a low risk of infection. This procedure may be performed repeatedly and is expensive.
