Fixing doll hair with fabric conditioner.
I used Marks and Spencer own brand cruelty-free fabric conditioner with warm water in a small water spray bottle that I bought in Boots.
I rinsed the dolls hair with hot water and re-applied solution where needed.
Each treatment should be left on the doll for 4 hours minimum and hair should be left to air dry. Use a tall glass to put the doll in so they can stand up.
