I am recovering from a broken wrist and needed my husbands help in washing my hair. Well not an easy feat, I have long thick hair. Lucky for the showr chair. It was a bit of a nightmare to say the least but we got it done, now on to drying it. Wish me luck
Hi @I am still oxox ,
I'm glad that your husband was able to help you wash your hair. 
As @JeanLouiseFinch mentioned in her comments, shampoo shower caps can be really helpful when you're recovering from an injury or illness.
I used them in the hospital and then have used then at home during surgery recovery.
I am currently using them again now.
You--or if someone is helping you--can wash your hair wherever it's convenient for you to do so, like sitting in a chair on on the bed, for example.
They're shower caps pre-filled with a pre-measured amount of shampoo and conditioner.
You can gently warm the cap up in the microwave for several seconds before placing it on your head.
You then bundle all of your hair up into the cap, and then massage your head and scalp through the shower cap for a few minutes. This wets your hair, and this is how it gets washed.
I keep a towel handy when I'm massaging my head and scalp to catch any water that drips from the cap.
When the time is up for you to stop the massaging, you then remove the cap and have your towel ready because some excess water will come out of the cap.
You would then dry your hair and style it like you normally do.
