Frizzy Hair! Help!!

Emily

Long story short, my MIL cut my SO and my hair about a week or two ago, and since my hair has lost its extreme straightness and has turned into a frizzy mess that I can’t let down 😭

Same with my SO, but his hair used to be SUPER curly 🤷🏼‍♀️

Is there any products that we could use to help with this?! I’ve tried looking but I’m absolutely dumbfounded...
