It looks like you have enough hair to get good results with concealer. Have you ever thought about trying a good quality concealer such as Dermmatch?
Some hair replacement systems can make your hair loss worse and can prevent you from being able to treat your hair loss. In my own struggle with hair loss, I have worn hair. It wasn't the best way to go - but I originally did not have much choice. However when I first started to wear wigs I had a few rules. First and foremost it was not allowed to make my hair loss worse, many systems do just that. Second it was not allowed to prevent me from being able to treat my hair loss. Third it had to be something that I could put on and take off myself without any help.
There is nothing wrong with wearing hair if it helps you feel better about yourself. I just want you to know that you probably have more options available to you than you think you do.
