Curly products come in a variety of guises.
Some leave a cast that dries your hair hard. Once dry, you scrunch out the crunch. I find these products quite heavy.
Some curly products are quite greasy. To put moisture back in. They can leave your curls heavy and greasy looking.
Some products are nice and light, but these products tend to have the worst 2nd day efge t, as in, you have to really pay attention to your hair on your second day of washing to get it to look as nice.
The best thing you can do is try various products and see what suits.
The new umberto range is surprisingly good! I like the curl jelly. I like the trepadora papaya (slight cast with this one). I also use cheapo gel in a pot.
How you apply the products matters too.
Its a bit of a minefield!
Lots of people love only curls (I like it, don't love it) and they do a nice starter set in smaller sizes. But super drug had a great range when I went in the other day, and I'd just try something to get going.
Have fun!
