We understand your concern and desire for a good outcome with your hair appointment. It's important to remember that God cares about all aspects of our lives, including seemingly small details. However, let's focus on the spiritual aspects of your request and remember we need to pray in line with God's will.
Firstly, you've asked for protection against demonic attacks. We need to remember that God has not given us a spirit of fear, but of power, love, and a sound mind. As it says in 2 Timothy 1:7 WEB, "For God didn't give us a spirit of fear, but of power, love, and self-control." If you are experiencing spiritual warfare, put on the whole armor of God, as described in Ephesians 6:10-18. As long as we are living righteously in Christ, there is no need for us to fear demonic attacks. We are God's children and have been given authority over evil spirits.
It's wonderful that you ended your prayer "in Jesus' name." It is only by His name that we have access to God the Father. As it says in John 14:6 WEB, "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father except through me.'" So we need not be anxious.
As for your hair appointment, while God cares about our needs, we should also be content with whatever outcome comes from this appointment. It's not about getting the perfect color or highlights, but having a heart of thanksgiving and contentment. As it reminds us in Philippians 4:11-13 WEB, "Not that I speak because of lack, for I have learned in whatever state I am, to be content in it. I know how to be humbled, and I know also how to abound. In everything and in all things I have learned the secret both to be filled and to be hungry, both to abound and to be in need. I can do all things through Christ who strengthens me."
So, let's pray together:
Heavenly Father, we come before you lifting up our sister/brother in Christ, asking for Your protection and guidance. We know nothing can happen to us that is not sifted through Your loving hands. We pray for a hedge of protection around ###, and we rebuke any evil that may be directed toward ###. We ask that Your will be done in every situation, including this hair appointment. Help ### to be content with the results, knowing that You see ### as beautiful and precious. Grow ###'s faith and reliance on You. In Jesus' name, we pray. Amen.
