Should I continue to wait after no progress from PRP hair injections?

Visible results with PRP scalp treatments are typically seen as early as 8-10 weeks but can be longer depending on thinning conditions. I highly suggest monthly treatments to stimulate growth for miniaturized hair follicles. Best, Dr. Anil Shah

You don’t need to worry, two months is still considered slightly early to see results. Consistency is key, however. The general consensus among reputable PRP physicians is that receiving treatments every three to six months on a long-term basis are optimal for continuing to stimulate the growth factors and stem cells that are associated with regrowth and stopping hair fallout. It's also important to keep in mind that PRP can, and should, be a part of a multifaceted program to treat hair thinning and loss. I personally prescribe finasteride or spironolactone as well as hair regrowth products like groMD to help promote hair regrowth, as well as other topical treatments like over-the-counter minoxidil (Rogaine). 

It can take 3-6 months to see results. Prp is effective, but I have a very specific protocol, every 3-4 weeks for 6 months with prp therapy. I also add in progesterone to speed the healing process.  After that the injections are tailored down. You should also be on viviscal and other growth promoting ingredients. See an expert for a formal evaluation. Best, Dr. Emer
 

On average, scalp hair grows about 1 cm/month or about 1/3 of an inch. Hair growth is a slow and usually frustrating process that requires a lot of patience and perseverance. Whether you are using minoxidil, PRP, Spironolactone or other treatments, you must simply wait for 3-6 months of growth at a minimum before knowing if it a therapy is helping. For our male patients who are taking finasteride (Propecia) we often don't see the full effect of the medication for up to 2 years after they've starting taking it.   We encourage our patients to commit to three PRP treatments and then come in for a follow up visit no sooner than 3 months after the last treatment to determine how well they are responding. We also utilize the Hair Check device to measure smaller increases in growth that can’t be see easily through photos.  Be patient and don't give up, this is a lifelong commitment.  

It takes 3-4 months to see results from PRP for hair. Most injectors use a very low concentration PRP and results aren't nearly as good with this. I use a 6x PRP which is what gives the maximum results. I also add ACell or amniotic membrane to improve the results. Microneedling at the end will also help. The problem is that machines which yield high concentrations of PRP are expensive and that makes the cost more to the patient. Females should need only 1-2 treatments to see results which last 12-18 months.

Although some see results after a couple of months, it typically takes much longer to see progress from PRP injections.
