I think yes in 20 years probably because my opinion is that in 20 or 30 years they will be growing organs and hair will just be one of them. Multiply a ton of them cheaply and implant back into your head its just a matter of time before that happens. It avoids most of risks like cancer which are always there if your injecting or doing other internal methods. Its just really hard to pin a time on it because its so unpredictable.
So anyone saying male pattern baldness will never be cured I think is completely wrong, and I think there is a good chance we will see a cure for male pattern baldness in our lifetimes.
