Argan oil is good stuff. It's 'light' and doesn't weigh the hair down. Also, itching can be the result of leaving the unit on too long and not washing the scalp. I know that Hair Club does what's called a 'hard bond.' It is tape and a super strong glue combined and it lasts about 6 weeks. This allows 'crud' to build up on the scalp and cause itching. To counteract the itching Hair Club sells you a product called 'Alive' to apply through the mesh while the unit is on your head. The 'Alive' is an enzyme that dissolves the crud--not a good substitute for removing the unit and washing your scalp.
