Question

There is a treatment known as PRP (platelet rich plasma). In this treatment, blood is drawn from the patient and then inserted into a machine where it is spun for approximately 30 min until all the components of the blood separate. It is then the plasma portion of the blood, which is rich in platelets and other proteins that promote healing and growth, that is re-injected into the affected site of the body e.g. an injured muscle, etc. Generally, PRP is used to promote hair growth, assist with healing tendons and ligaments that are injured, assist with osteoarthritis, assist with healing brain damage, etc. Is PRP permissible in Islam for hair growth and healing?
