Is there a way to improve retreating forehead?

Without photos , its difficult to provide much information.See my previous answer on receding hairlines.   Surgery,  hair implants and IGrow along with medications can all help

Thank you for your question.  If you have a hairline that starts sloping backwards on your forehead, hairstyling should hide it or an implant can be placed under the skin to give a more rounded look to your forehead.  If you do not have hair, then hair transplants can also work.  Again, it is difficult to assess without a photo.
