When is it safe to restart low level laser therapy (LLLT) after 2500 FUE Neograft procedure?

Thank you for posting this question. The reality is that there isn't a set protocol for using LLLT following a hair transplant procedure, whichever method or machine was used to perform the transplant. Our protocol is to have our patients use it starting the day after surgery. We find it helps to decrease the scabbing around the grafts which can be helpful for optimal growth. Clearly putting a lot of pressure on the implanted grafts the day after surgery is not indicated, so common sense is indicated when using the device following surgery. I hope this information is helpful to you.Ken Anderson, MD, FISHRS, ABHRSBoard Certified Hair Restoration Surgeon

Thanks for your inquiry, we start LLLT within the first week on free standing machine that does not touch the delicate grafts. If you are given a cap, please make sure it is not damaging the grafts and might be more prudent to wait a full week.

As others have said, there is no consensus of thought on restarting LLLT after transplant, but I would say above all, don't touch the grafts.  The LLLT itself is likely safe starting the day after the procedure.

There is no harm with use of LLLT (low-level-light-therapy) post grafting. However, one must be careful about applying pressure to nascent grafts. Many of these systems involve the use of a helmet. Proper seating of the helmet is essential for these treatments to be effective. However, post op you need to avoid placing any pressure (direct or indirect) on the newly grafted follicles as this can compromise graft integrity.Protocols will vary from practice to practice but I will typically discourage helmet usage for 2 weeks at a minimum.As always, discuss your concerns with your board certified plastic surgeon (ABPS) with experience in hair restoration.

The main reason I recommend low level light therapy is actually for the swelling and inflammation. Generally all patients will also get oral steroids as the inflammation from the surgey can worsen graft outcome. While there is no proven scientific data or protocol on LLLT after transplant, to me the benefits of decreased swelling (studies on swollen sprained ankles for example) manifest that LLLT given either right after via a screen or the day after via a hat module are very beneficial.
