I am also researching SMP. I mainly want to cover up a scar from a regretful hair transplant. It is very hard to find enough information on SMP. I have researched and got quotes from good look inc, his hair clinic, & scalp aesthetics. The reviews on this companies are all over the map and they only guarantee their work for a year. That is ok i guess considering my hair transplant didn't guarantee anything except leaving me scared however what I don't get is how they determine the number of sessions you require because each one gave me different number of sessions. I wanted to do the front of my head too but I am worried just like you on what it would look like long term. I haven't even seen pictures of people over a year let alone 5 years. oh I am so frustrated I wish I can go back in time to undo my worst decision.
