Synthetic sheitels are very low maintenance. You buy them in a preset style and you wash them yourself and it will just set back into the style. There is no styling.
They don't last as long as real hair does-be prepared for them to last 6 months - year of daily wear before they start looking like mop heads.
But they are a much cheaper option. I love how you don't need to worry about getting caught in the rain as they won't go frizzy, and that they are just cheaper in price.
Of synthetic? I didn't know you could. I thought it was whatever style it was, that's the style it will stay. I mean you can pin it back etc, but I didn't think you could use hot styling tools like curling tongs on them. Heat will kill it.
If you want to do it properly, it may be worth it to take a course on this. There are sheitelmachers in bp and kj that do 3 hour classes to teach just what you're looking for. I know some sm even give private session to teach this
