Hi Cric,
Those are all good questions. And congratulations on ‘taking the plunge.’ You’ll be surprised at how this is going to change your life. You’re right about the density--it’s heavy. Order about 80-85% density. The hair is not perfectly straight as there’s a little bend in the hair. Body wave is way to go. When you first receive your unit it will look very wavy and you’ll think the factory made a mistake and didn’t do a body wave. But that wave comes out when the hair is combed and washed so please don’t be concerned. If you have normal side hair there’s no need to draw arrow for hair direction on the template. However if your own hair does not go up as far as the guy in the photo then you would need to draw arrows downward. The factory will follow whatever you put on the template and if there’s no arrows going downward then they’ll vent everything backward. The style is comeback. This will give you the ‘lift’ you want. It’s different than flatback venting which vents the hair at a steeper angle that puts the hair closer to the scalp--hence the name ‘flatback.’ Got 2 Be Glued is a good product. It’s simple and easy to use. The best part about it is that it’s water soluble. You only need to rinse it off your head and the hair system to clean it off. The downside of G2BG is that it is not a strong adhesive. But that’s not necessarily a bad thing as many hair wearers like to frequently remove there units to clean their scalps. Going longer than 2 weeks without removing your hair system can cause the scalp to itch. G2BG original purpose is to spike up hair. I get about a 5-7 day hold with it and I consider myself to be moderately active. Of course mileage will vary according to driving conditions. Hope this helps.
Regards,
John
