My hair type is similar to yours, it’s quite fine in texture and with the added colour has lost its bounce. I use L’Oréal professional shampoo for coloured hair which does make my hair less frizzy but it was the color wow dream coat for curly hair that was a total game changer - I can spray it and leave it to dry now without it ending up looking like a frizzy mess. It softens but gives definition too. No hold to it so you could add something else for if needed, they do a purple mouse for blonde hair that I might try but at the mo for everyday I’m happy with just the spray on its own. Great for 2nd day refresh too.
