Acell + PRP for Hairloss?

ACell is not something that I use currently in my practice. There are more and more studies recently showing the benefits of PRP alone. I often use PRP in conjunction with other hair loss treatments or in conjunction with a hair transplant session. 
PRP injections are not FDA approved, like many other treatments in medicine that work. This should not be a discouraging factor as this simply means that there has not been adequate scientific study (usually by a specific pharmaceutical or device company) to go through the processes required by the FDA. There are many treatments for various ailments and cosmetic concerns whose efficacy is clearly established, yet there is no FDA approval.
PRP injection prices will vary widely from one provider to another.
PRP is a great option for many patients. See a fellowship-trained hair restoration surgeon to discuss all of your hair restoration options in detail.
All the best,

Platelet-rich plasma has been utilized for years in wound healing and orthopedic conditions, but more recently it has gained traction in aesthetic medicine, especially with respect to hair loss. Several clinicians have had some success in treating alopecia of various etiologies (lichen planopilaris, alopecia areata, etc), but most of the limited data have been focused on PRP use for male- and female-pattern hair loss.
The mechanism of action involves platelets’ ability to aggregate together, activate, and release alpha-granules containing various growth factors, such as platelet derived growth factor, transforming growth factor beta, vascular endothelial growth factor, epidermal growth factor, fibroblast growth factor, and insulin like growth factor-1 (IGF-1). Their release increases angiogenesis and vascularization, providing resting telogen hairs the signal that they need to enter the anagen phase. This increased vascularization and mix of growth factors also fosters the proliferation of dermal papilla cells and inhibits apoptosis, helping to prolong the anagen phase.More specific to androgenetic alopecia, PRP may help to counteract certain effects of dihydrotestosterone (DHT). In a mouse model of androgenetic alopecia, DHT was shown to block IGF-1 contributing to hair loss and PRP is a known source of IGF-1.
Platelet-rich plasma is fully autologous and thus provides patients a more “natural” treatment, with side effects limited to procedural discomfort and bruising.
There is no standard system, quantity, or interval of treatment regarding PRP for hair loss, which is why we currently utilize a proprietary hyperconcentrated platelet rich plasma concentration and treat patients monthly 4 times, then reevaluate after 8 to 12 months. If a patient has a response, then retreatment at follow-up may result in continued efficacy if performed at a 6- to 12-month basis.

Although there are those who feel the combination of A Cell with their PRP injections adds to their patient's hair restoration results, I have not seen any clinical studies that prove that there truly is a benefit.  I have seen significatn results using PRP treatments alone which are backed by some clinical studies.  A Cell is very expensive and I don't see the value of the added cost to the patient.  If some studies come out proving A Cell's  added benefit vs. PRP alone I would consider adding this to my PRP treatments especially if it can enhance and prolong the PRP results- requiring less treatments over a long period time = cost savings.
