There's a variety (as listed by previous posts) but in general you could use the following (and not limited to):
1. Wax: if you want a stronger hold and plan to keep a particular style for a longer amount of time (products from Hanz De Fuko :love: and By Vilain are awesome and keeps your hair consistently in place plus you can choose different types of finishes = a.k.a. semi-matte, matte etc. pricey but imo worth it)
2. Mousse: for a very light hold plus these products usually come with extra benefits like moisturizing properties if you desire 
they're pretty easy to use and usually doesn't weigh your hair (just feels natural but depending on product)
Have fun experimenting
