Hi Could someone make my hair darker like the girl's standing next to me? Thank you for any replies.

@Rich54 did a great job as always.
Just a try on my part. Also got rid of the thermostat, toned down the highlight on the forehead.
Had to stop since I ran out of time...heading out to my daughter's wedding ceremony...finally...
