Don't use surf hair without a drop of a silicone based product. It can dry the hair out. I used it in the past but I haven't touched in in over a year.

For that look I doubt you want a matte product. Probably a light wax. Pastes and heavy waxes can really gunk the hair up, and that looks like the opposite of what you are trying to achieve.

Styling products are tough. Not too much on the market that was developed specifically for hairpieces.

Keep in mind that the absence of alcohol doesn't mean that it will work well for processed hair. It's kind of a trial and error thing. I'm actually getting pretty close to starting R&D on some styling products that are formulated specifically for processed hair, so hopefully sometime next year there will be more options.
