Platelet Rich Plasma (PRP) and ACell Dallas

For more information, please watch our videos on Platelet Rich Plasma (PRP)

In our office, Platelet-Rich Plasma (PRP) and ACell are always used during a surgical hair transplant to improve graft survival and thereby the overall result. However, in some selected candidates, Dr. Lam performs standalone PRP and ACell injections to the scalp for hair loss without concurrent surgery. These injections can help stimulate balding hair follicles in both men and women to slow down and partially reverse the hair-loss process. PRP is composed of the active portion of platelets purified and concentrated through a centrifugation and distillation process. These concentrated platelets contain a high percentage of growth factors that act to stimulate hairs into a growth phase. They must be activated to achieve their purpose in restoring hair through either a mechanical or chemical process. Dr. Lam uses both methods of activation in order to ensure the effectiveness of the PRP. All PRP “formulas are not the same. Dr. Lamhas worked with the lead scientific officer of the company to develop the ideal platelet titration for optimal results. ACell is an abbreviated way to refer to ACellMatristemMicromatrix which is a fine, granular powder consisting of acellular (cells removed) portion of porcine bladder matrix. This acellular scaffold has been used to rebuild lost tissue in plastic surgery and in this case is used to enhance the effects of the PRP and to stimulate further hair growth. The combined effects of both products are synergistic in their potentiating ability to regrow hair.


Platelet-rich plasma (PRP) can be used to improve hair loss, as shown in this example. However, PRP does not always work without surgery and can have variable results. Dr. Lam does believe that PRP is an essential component to hair transplant surgery and can truly improve clinical results.

It is important to point out that PRP/ACell treatments are not a substitute for a surgical hair transplant but instead can act as an additional (or alternative) method to other medical therapies like finasteride (Propecia) in men, low-level laser therapy (LLLT) in men and women, and minoxidil (Rogaine) in men and women. Like these other treatments, they are more effective when hairs are miniaturizing, i.e., are in the earlier phases of loss and are ineffective when the scalp is bald (or mainly devoid of hair).

If you are considering PRP and ACell treatment, you should know that it is difficult to predict how effective this standalone treatment would be for you. Dr. Lam has found that there is almost always improvement in the right candidate but the result can be small to large in scale and there is not as consistent an outcome as compared with surgical therapies. Those who respond well (which should be evident in a few months) should continue these treatments. Those who respond less ideally should most likely abandon this method of intervention. The frequency of treatment is also tailored to the individual. Someone with progressive hair loss should have more frequent treatments like every few months to twice a year. Those with slow hair loss most likely could have sessions between once a year to once every other year depending on the nature of one’s hair-loss progression. The session itself is typically a very simple office procedure with perhaps a few days of mild to moderate (and rarely significant) swelling. You should be able to drive home afterward.A consultation with Dr. Lam and his team will help you determine whether you are a suitable candidate for PRP/ACell and recommend the best course of action for you.
