Be aware that there are non-surgical hair restoration options. There are medications such as topical Minoxidil for male and female balding which can be purchased over the counter. For men with balding there is a medication called Propecia (Finasteride 1mg) which is a tablet that can be obtained on a private prescription. It may also be possible to obtain this topically.
There are some side effects in some people and a careful assessment of health needs to take place before this medication is prescribed.
How people respond to these medications is likely to be genetically programmed. There is a genetic test called TrichoTest which can be used to work out which medications are more likely to work based on your genetic profile.
