I used a hair system for 17 days and I had to call it quits. I hated not being able to enjoy a nice shower while wearing the hairpiece. It was a struggle sleeping with it. It also itched like crazy sometimes. I had to limit my activities like not playing a lot of basketball, cutting my grass outside or running. The hair stylist used glue and tape which was an ugly combination in the hot humid summer months. You are supposed to use a sulfate free shampoo with conditioner when you shower. GOOD LUCK SIR!
Unless you are a professional and can clean and re-attach your own hairpiece every week its not worth it.
You are also suppose to learn how to lift the front of the hair system only to do a quick front hair line cleaning or else you will experience a dirty gray line that forms on your forehead due to sweat and dirt that accumulates daily. There are really good YouTube videos.
Search for a "mg ford" on youtube. He has really good videos on how to do self maintenance on your hair system. Here is the link.
