How many PRP injections (hair loss/thinning) to maintain/improve results?

Thank you for your question. Usually we recommend to have 4 treatments every 4-6 weeks during first year , and then 1-2 treatments per year following years for maintenance.

We generally suggest PRP treatment 4 times per year. After the first year you can do it twice a year.

Unfortunately, there is no wide consensus on scalp PRP injections for hair loss in regards to frequency of sessions due to lack of landmark studies researching this topic. However, some institutions have created recommendations that may offer most hair loss patients a general timeline/frequency of sessions during the first year and subsequent years where the outcome may be optimal. This should be discussed with your specialist to optimize your outcome. As with most remedies/solutions for hair loss, the therapy should be continued in order to have the ongoing benefit of the hair loss treatment otherwise the hair loss may resume. Additionally, when choosing the right physician for this, make sure they are comfortable and experienced with scalp PRP injections as the depth of injections, frequency, and overall understanding of hair loss pathology is very important.
