Is my hair suitable for PRP? (Photo)

There are many patients with moderate to severe androgenetic hair loss who wonder whether it's worth it to do PRP or go straight to a hair transplant procedure. Each situation is different and likely depends on several factors. Consider your goals and where you are starting. PRP might improve hair density and quality, but results would depend on concentration and dose of platelets in the PRP, age and overall health, type of PRP system used, and whether you are combining with other treatmetns at home such as microneedling, topical growth factors or medications (e.g. minoxidil, finasteride), low-level laser therapy (LLLT), Vit D, massage, etc. In general when considering moderate to severe hair loss, transplantation will have better results, however there are important considerations and even transplanted hair will not last forever.
For a hair transplant procedure to work well, you need enough healthy donor hair to transplant to the balding area. PRP used before, during and after the transplant procedure can improve results as more donor hairs will survive the transplant process. Like PRP, the other supporting treatments could help to improve the blood flow to the scalp and thus the hair itself. Without support, the donor hairs will eventually suffer the same fate as the hairs that were in those areas in the first place (miniturization, shortened growing phase and eventually hair loss).
As for the interval of PRP treatments, a recent meta-analysis by Georgescu et al in the Journal of Personalized Medicine showed that closer intervals are associated with better outcomes, so you might be advised to have the treatments every 2 weeks instead of every month. You could also consider other adjuvant treatments with PRP such as Acellular matrix (Acell), or at the very least microneedling.
In summary, PRP and other regenerative treatments can help whether or not you are going to do hair transplant. It's important to support your hair growth at home using other treatments as well. Transplanted hair also needs to be supported for long-term survival.
