Please avoid gels and mousses containing alcohol. Most do contain alcohol and they will rapidly dry out and age your hairpiece hair. Hair serums are great for hairpiece hair and so are some creams and pomades, but avoid product buildup by using a clarifying shampoo occasionally.

Try one product at a time, but don't mix, for example, a silicone based substance like a serum with an oil based substance like hair cream. You might end up with strange feeling hair and have to wash it all out and start over.
