Looking for hair advice.

My bf has chest-length, semi curly hair that's a bit on the dry side. Somewhere between 2b and 2c. His roots stick up a bit giving his hair a puffy appearance, and he has these frizzy-looking flyaways on top of his hair which exaggerate that.

How can he fix this? Will adding moisture help? Rn he uses Pureology hydrating shampoo+conditioner. No other products or heat.

Basically trying to get his hair to have a relaxed, loose, and neat look like this pic.
